  1. may be on to something

    overview: 1) vacuum is useful in mycology 2) vacuum is easy to produce I came across an old window ac unit and scrapped it for parts. The compressor worked so I made a vacuum pump out of it. I put 1 cup of grain in a jar with 2 cup water and hydrated it in less than 3 min. I am on my first day of trials but it looks all good for grain hydration. When the pump turns on the grain is evacuated of air and when normal atmospheric pressure is returned to the jar the empty air space is replaced with water. My vacuum hydrated grain is 100% larger than dry grain. If I put 1 cup of oats in I get 2 cups out. I am working on a grain hydration tek using vacuum. I would like to know of any issues with grain prep that may be overlooked as of yet. (I am a nooob here but no stranger to hi vac) where can this lead to???? 71% alcohol wil sterilize grain and vape off leaving 29% water - if enough is used it could leave grain at the correct water capacity. -not tested evap of water off substrate is a great pinning trigger. vacuum evaps water. -can we just put sub in hi vac for a few seconds and induce pinning? -not tested ************************************** this is my firs attempt at an open source project to benefit my people (mushroom people). input and open trials welcome. So far I am mostly excited about hydration. I have a quick and easy way to turn your pressure cooker into a vac chamber. you only need to not be too cheep to buy a thick piece of acrylic and be handy with common tools. I know that excludes a lot of people but it could be worth it to the rest of us. the acrylic sets on top of the pressure cooker (with out the pc lid) but still has the lid gasket between the pc and the acrylic. all the vent and vac lines go through this acrylic so you don't need to modify the pc at all. more to come on this .... if its welcome. ******************************************* Hit me back with ideas or things that are important - like known conditions that must be met. I will be working on this as a side project for some time and am willing to help anyone get there free/cheep vac pump set up going if they wanna help get results. ps. rt now is when you will see window ac units free or cheap. any appliance that makes "cold" will have a compressor. If you see an ac or fridge cheep/free get it for the compressor. that is a vac pump. alternatively you can buy a vacuum pump but it may be too strong to use with jars.?.?.? a side note... if you are really concerned with safety don't get involved till a tek is perfected. hi vac is just as dangerous as hi voltage or hi temps.
  2. Hey, all. So, I am doing WBS in quart size jars. When I first made them I put verm on the bottom and didn't do any particular field test for moisture, just kind of eye-balled it and compared it to videos I have seen. The moisture seemed good. For the first half of the incubation period I was holding a relatively constant temperature of 78F. The last half I fluctuated quite a bit. For a couple days I had temps into the low 90s then others days I had temps as low as 69F. Out of 22 jars only 7 were fully colonized by the month mark. The rest ranging from about 60-90% colonized. I left them in for another week to give them some more time but growth seems to have halted. I attribute it to the high temps and not as accurate moisture content of the WBS, but I see a lot of people not being super specific as well as a lot that are insanely specific on what to do when preparing their grain. Now my question; I went ahead and spawned 4 of those 7 fully colonized jars to bulk, they still had some visible moisture in the jar but they just looked a little dry. Is there a temperature and moisture content that the jars could get to that would kill the myc. or are they pretty resilient. Since I added them into my hydrated coco coir substrate will they just use that moisture and start growing again? How does that process take place? I understand the importance of changing temps when going to fruiting but I want to know if I fucked myself by having these varied temps during incubation. Thanks.
  3. This is my first time trying. I innoced my jars on 8/29/17 and 4 days later I have my first sign of progress! Super excited hopefully they don't stall out because I over filled them.. not filled all the way though. I might put them in an incubator for a little help. We will see how I do as the progress goes on. It's not much but all 10 jars started today.
  4. When prepping oats, do I need to take out the floaters like wbs? It has little prices of hay in it too. Or just soak and simmer and dry and load?
  5. Im a completely new grower and I am going to try the Rez Effect technique that i found on here. Once everything is in the bin should I leave the lid on or off the bin?
  6. I recently prepping some grain spawn made from WBS using MushZombie's "NO FAIL wbs tek". However, the tyvek envelope shrunk while PCing, exposing the entirety of the jar. I pressure cook using the minimum amount of water, and only barely PCed for an hour and a half at 15psi. Has anyone else had this problem starting out? Thanks for any suggestions in advance!
  7. Did I screw up?

    Hey Guys, So I set up to start another set of grain spawn, but I missed a step and I don't know if I ruined this whole set of not. I'll walk you through what I did and where I went wrong. Rinsed the sunflowers out of my WBS. Added boiling water to WBS in 5 gallon bucket and snapped on the lid, allowed to sit for 90 minutes. Strained WBS and rinsed thoroughly with cold water, didn't really let it dry at all. (Which after speaking with everyone last night I now know I should let it dry for about an hour) Added 1/4 coarse verm to bottom of mason jar, and then filled jar up to the 3cup line on the jar with my prepared WBS. PC'd for 90 minutes at 15 psi and then allowed to cool overnight. Now here's where I went wrong, I knew I was going to have to work late so I wanted to noc my jars before I left for work. Did all of my sanitation prep just fine but I forgot to shake the jars! slipped my mind in my haste. so I basically pulled straight from the PC and noc'd. I realized my mistake as I was putting them in my incubator (a closet that stays around 78-80*). Realizing my mistake I decided I screwed up anyway and wanted to see what would happen. I had prepared 5 jars in total, so I took 2 of the jars and did the normal shake being careful not to disturb the verm. I left the other 3 jars as they were, so they have had no shaking what so ever. How do you think it will come out? Advice for how to handle the situation in the future? Also side question, This closet that I'm using for an incubator naturally doesn't get any light except for the glow from the lights of my computer tower. What do you guys recommend for this stage? No light? Natural light? Comp tower light bad or no difference? They are just sitting on the shelf should I put them in a box? I'm a nooby full of questions and I love you guys for your patience and wisdom.
  8. If you grains are sitting in liquid, then obviously they are too wet. This could cause contamination, but contamination itself is not a sign that they were too wet. I am more inserted in there in any observable properties by the mycellium itself. --------------------------------- After loading your Grain into Jars/Bags, then inoculating them: What are some signs/symptoms that can be observed with Grain that was too Wet? What are some signs/symptoms that can be observed when your Grain that was too Dry?
  9. How does this jar look to you

    i would like an opinion of my jar please. this photo was taken after shaking the jar around 60% do distribute the spawn. just wanna make sure its nice and healthy.
  10. I follow the soak, simmer and pc method for preparing my wbs. my question is how long do i have to noc the jars? i prepped a little more grain than i needed and i had to order more spores.
  11. 2nd flush with these jokers! I'd say they turned out pretty good. Some of the biggest I've EVER seen!! What do the experts think??
  12. Exhausted N00b need help

    Hello noob here, and honestly too mentally exhausted to comb through all these topics. So I need some help if possible. I have follow the bulk dub tub tek to a T. Everything had gone great until the fruiting process. One tub had to be dumped because of mean green, which sucked because out of the 4 I have. That was one of my "perfect had everything going for it" tub. Along with one other. So 2 tubs that had 2 full colonized jars put into it. My other two tubs I called them "Frankensteins" because I just took clumps from multiple jars and put in the tubs. Also I ran out of casing layer so those two didn't get a full casing like the others. So here is my conundrum. My star child tub still hasn't spawned anything, been misting and fanning. Both of the Frankenstein had some cobweb, cured that. But one of them is pinning in the corner. Like a cluster. Now understand, that this one is the one i didn't think would do shhhiiit because of barely any casing layer and had not a full spread of myc. So I guess my question. How is the one in the least amount of cared condition the one pinning? Especially after I h202 the crap outta that cobweb. Here is some pics I'll take any advice, all advice, I'm just concerned that I have effed up the fruiting process. Here's my tubshere are my 3. Far left is the pinning one. Middle a Frankenstein and the last one tek followed to the Tdon't understand what is special about this corner. Wish I knew or took pics.star child not pins but has been pulling away from the walls which I read was a good sign? So do I need to just build a good FC? Should I panic? It's been 2 weeks in the fruiting process with the 50/50 casing. Thank you for your time
  13. My casing layer is like being eaten?? There's like white stuff kinda reminds me of barnacles almost. Am I dealing with a strain of mold? I have seen another post with someone having the same thing but mine is like 2x more Any advice/help is much appreciated thank you!
  14. PE.

    Hey, I have PE that I probably should've harvested before I left town last week. I didn't have time and sorta forgot in the midst of getting everything ready. My question is, is there any reason why they wouldn't be ok to pick now. Well, I've already picked them.. they seemed fine. Normal smell. Just a different texture. They weren't as solid feeling as they usually are. And some bruising. I didn't take a pic!!
  15. Hello new shroomery here, question. Having a hard time finding fruiting chambers for 6qt dub tub bulk spawn. Was curious if there is one, OR a better way to environmentally control my fruiting process?
  16. Can Metabolites stain mycelium?

    Hello Everyone, Does anyone know if metabolites can stain mycelium orange? I notice that in my Blue Oyster grain jars (and them only), I have been seeing orange spots. Some of them have a wet appearance but others look dry. Are Blue Oysters known for creating a lot of metabolites? Is is possible that it is a contam? Metabolites? Both? I have included some pictures of the wet looking ones. The dry ones I already pc'd (just in case) . The grain has been fully colonized for awhile. Rye Grain w/ tsp of gypsum Pc'd 1.5 Hours 15psi
  17. First flush today!! Pretty happy with the results. Gonna make some tea in a few hours. Just dose the same amount as with all cubes? I wish I had taken a pic when I opened lid.
  18. This is my fist grow. Ive followed the WBS bulk grow tek outlined here. Ive used ZTubs as my fruiting tek. And I really wish I'd started a grow log like it was suggested to me in the beginning! Next time I will. So a week or so ago this tub appeared to possibly be contaminated. I'll try to find pics that I posted of what looked like maybe cobweb. I decided to open up tub and treat with h2o2 and try to save it. I had another tub starting to fruit, so after spraying I set it aside and honestly kinda forgot about it. Then I saw that it was starting to pin so I began nursing it. Misting and fanning. This is what I've ended up with. They smell fine, and nothing visibly different with them. So what do yall think? Safe?This last pic is what the "contamination" looked like. I know its difficult to determine much from pics, just curious about opinions. Thanks!
  19. Hi, everyone. Thanks for putting together such a great site. Great vibes from all the people here, too. Is it ok to PC karo/water pint jars for liquid culture and WBS at the same time? The WBS minimum PC time is 90 minutes, but the LC tek states 30 minutes. Will going an extra 60 minutes "hurt" the karo/water mixutre? Thanks in advance.
  20. Hello all, and Merry Christmas! i have a few wbs grain jars that are right at 100%. Im going to my folks for Christmas, is there any harm in them continuing to grow in incubator for a few extra days? If i were gonna be home I'd prolly put them in tubs tomorrow. Also, i prepped and PC my coir substrate about 4 days ago. It has stayed in PC, in oven bag (with micropore tape covering air holes.) The PC was opemed to look at bag and the remaining water was poured off, then PC was sealed back up. Do i need to PC substrate again or start over if its gonna be 7-10 days total since its been PCd? Its not a big deal to do it again, I want the lowest probability of contamination possible!
  21. Hello friends. I have sarted, inoculated jars on 12\1. I know it's not the smartest move but I've started with PE, but also some Golden Teacher. From what I understand PE can be a real pain in the ass! Lol. Anyway, I've got jars in "incubator" and temp is consistently 78-80 degrees, I have growth and excited! I feel like they're looking good. We'll see, I guess. I check them every day (I know I maybe shouldn't). My concern is when I have 100% colonized jars and transfer to my substrate. I plan to use Ztubs with the 50/50 substrate. So here's my question or concern. Up until this point, contamination is my biggest concern/enemy. How is it that when I transfer 100% colonized jars to substrate it's talked abt so much less? I'm using a closet with a heater and jars are in a cardboard box. When I transfer, I know I use sterile technique, and Lysol the air before I start.. But after its transferred, covered with foil (holes with micropore tape), and placed in my closet at incubator temps, am I still concerned with air contaminates?? Do I need to work harder to "sterilized" my closet or should I run my HEPA in there along with the heater? I know this is probably weeks away, but I like to think everything through, and I just like to talk abt with you guys. My biggest issue during that period is going at least 10 days WITHOUT LOOKING!! Are they gonna be ok? Wont they miss me and our conversations!?! Lol
  22. CaptainRabbit ZTubs

    Greetings EARTHLINGS. I now present to you, for entertainment purposes only, my first grow log. I am using mycelium spawned onto rye berries. These jars were nocced from 1 quart of Treasure Coast. This set of jars is the third generation post spore syringe. Nocced date Oct 2, 2016. So that's 9 days now. Incubated at 80 F. Jars were PC at 15 psi for 60 minutes, and cooled overnight. GTG TX was accomplished inside a cardboard box GB. 1 quart to 7 quarts. Jars were covered with a single layer of Tyvek for lids. No actual lid. (I suspect this is causing the grains on the very top to dehydrate. Dehydrated grains will be discarded.) I am going to use the Zombie Tub Tek. I have drilled holes out to a half inch, placed as shown in pic. >>>>>>>Questions: 1) After spawning into these tubs (lined with small black plastic bag, thin layer vermiculite, 1 quart grain spawn, enough coir substrate to raise the level to about 3/8 inch below the vent holes) I will lay aluminium foil directly onto the sub/spawn mixture, vent holes in the foil covered by microp ore tape. Now the question! Can I put the lid on now so I can stack them in the Incubator? 2) I am planning th is substrate as 100% coir. Is that appropriate? Should I add vermiculite to the coir? Should I add any buffer (hydrated lime?) OR should I just stick with coir? 3) obviously with this tape it up and leave it tek the original moisture level is crucial. Any tips other than field capacity testing? 4) tek directions say to use 1 qt spawn per ztub... of course my jars are only about 2/3 full, so since I have 6 jars should I end up with 6 z tubs, or do I actually need 1 full quart in each, leaving me with 4 ztubs? <<<<<<<<<<< I also have enough jars of panoeleous Cyanescens for the same number of tubs. Should I just treat them exactly the same, or is this the wrong tek for pan cyan? I'm quite excited about this, and wish to thank everyone at this forum for all of the knowledge within. This group is awesome. Mush Love... Rabbit.
  23. So I inoculated my grain spawn jars about 4 weeks, and they all seem to be growing exponentially everyday except for one of them (the photo I attached). This one jar has only had growth on one side of the jar (the side the photo is of), while the other jars have multiple zones of colonization, which is obviously making them grow faster. Should I shake this jar to redistribute it, or should I just wait it out?
  24. It's been 9 days since I spawned and everything looks great but they're these black splotches I see and I'm not sure if they're random spots of uncolonized spawn or not, can anyone enlighten me?
  25. I inoculated my grain spawn jars 12 days ago, which I'm using WBS. I have noticed a little patch of growth that the mycelium has colonized but only in two of the jars (I have 4 jars total). This is my first grow, so my question is how long will it take for the jars to be completely colonized, and how much time should I give the other two jars with no growth? Also, I have them an incubator away from direct sunlight, but it is not in complete darkness. The incubator is on a heating pad that raises the temperature by about 10-15 degrees. I attached a photo of the two jars with growth. The jar on the right appears to have some condensation on the inside. Does this mean there is too much moisture? Thanks
