What's wrong with my FC setup??

Recommended Posts

Samwise

Hi peeps,

Would appreciate some input on my current FC setup...I'm getting results, but they are inconsistent and not as great as they could be. I'm trying to emulate Don's "Low-Maintenance Psilocybe Mexicana Fruiting Chamber Tek" (linked below).

https://www.shroomology.org/forums/topic/16079-low-maintenance-psilocybe-mexicana-fruiting-chamber-tek/?tab=comments#comment-131652

In the FC at the present time, I have 2x trays of P. galindoi, and 2x trays of P. hoogshagenii 'Semperviva'. One tray of the P. galindoi is fruiting quite well, the other not so much. The Semperviva is a really slow fruiter, but a good amount of pins in one tray, and one single aborted pin in the other...given how hardy this species is, this has me concerned about my setup. I have some Mexicana 'Jalisco' and 'Chicon Nindo' LC standing by, but want to get my FC dialed in ready before I get round to fruiting them. For the FC I'm using a 64 litre tub, with water saturated perlite in the base, with 2x air stones connected to an air pump, two rows of holes drilled, one above the perlite, the other near the top of the tub, and there is a fan in the corner that comes on every 15 minutes at 6 hour intervals. Humidity and temperature in there are both fine. I'm not using a light currently (some growers recommend a blue LED bulb when fruiting Mexicana), but they do have a sky light above them are in a room well lit with natural light. Would it be a good move to get a light up and running to play it safe?

I've attached a pic of my setup...wondering if anyone has any observations on what the issue(s) could be here? I'm wondering if the fan could be an issue or weak spot here? Unlike Don's which is integrated into the side of the FC tub, it is not bringing in and circulating as much fresh air from outside (relying on fresh air being brought in via the holes only). The fan also being at one end in one corner of the FC could also be an issue, perhaps I would be better integrating it into the upper wall of the FC tub in the middle to give a more even distribution of fresh air. Any thought on any of this? Photo of my FC setup is attached.

Any input on this would be much appreciated! :)

I agree, looks like there is not enough fresh air, and not enough evaporation. Have you been monitoring temperature as well? Low temps, like cubes, are best for mexicana ime. also helps keep the RH up with lower temps, since the air can't hold as much water at lower temperatures.

Thanks a lot for the input guys, much appreciated, I thought it may be a fan issue. It's good to know that the aim of the game is to get stale air out of the FC (and draw in fresh air via the holes) with the fan; I figured it was more for blowing fresh air in, so I appreciate the clarification. I've just ordered a comp-USB fan off eBay so I'll get that integrated into my FC ASAP. The temps/humidity in there are both fine, so it is very likely a FAE issue I think.

your casing looks a little wet for sure.

Yeah, massive FC lid drippage deluge every time I open it, the fruiting trays and casing are a bit sodden. Hopefully with the new fan integrated into the FC and with the trays spread out more in there (rather than bunched together as they are now to make room for the current fan) it will allow for more air flow and help prevent build-up of excessive condensation and drippage.

to get rid of that, you need to figure out what the dew point is of the plastic, and keep the air inside of the fc within temperature rage of dew point, at the RH the fruiting chamber averages. the condensate reveals your air temp inside of the fc is quite a bit warmer than the plastic of the tub.

Good to know, thanks dude for your input, you're mycological gold dust. :)

Hey peeps, so I have the CPU fan and have made an appropriate sized hole for it in the lid of my FC. I just want to check something...in Don's linked "Low-Maintenance Psilocybe Mexicana Fruiting Chamber Tek" guide, he recommends having the fan blowing fresh air INTO the FC, whereas you guys seem to be saying the opposite, that the fan should blow [stale] air OUT of the FC (and draw in fresh air through the air holes). Wondering why the preferences vary here? And does either/or more or less achieve the same thing anyway? I just want to be sure on this before I fix the fan in place in the FC lid.

      The 3 Matias Romero cakes have finished their first flush and they all did great I wish I’d taken more photos Fruits are drying now in the dehydrator. Here’s one cake-

      Don’t panic. Your jars will be fine. You can actually wait till they show pins in the jar to birth them , if you have no idea when they’ve finished up.

      Those halogen lights are hot af. Are you sure it didn’t get too hot and dry out and kill the mycelium? I think anything in the mid 90’s+ can be heading for big trouble, but I’m not certain . But it still doesn’t look close to being ready to put in fruiting conditions, and has likely stalled a long time ago It shouldn’t take 3 weeks to colonize that tub though. It could be contaminated beneath the surface too. Im thinking it has just stalled out, it’s junk after almost 5 weeks, and I would start over. But maybe someone else will chime in with another idea  Sorry man, my deepest condolences.  Get a couple syringes from Source of Spores. Get some Pennington’s Wild Bird Seed from the super center,Composted cow manure and Coarse vermiculite to start , and you’re in business. Follow a tek closely,in our Bulk Grow forum for sure fire success.

      Yeah I incubated it for about 3 weeks by placing entire tub in 2 black trash bags and used halogen shop lights to maintain temp. l forgot the casing layer😬, what to do now? These are Burma strain from non-sponsor vendor, I wasted the azurescens sadly, they never even colonized the presterilized grain I paid neary 35 bucks on, they just all mushy and slimy 🤕🤧

      Wow those are awesome looking!   Blue!   Are those APE.  Had to look it up.  PE is next on my list.   What got me started on this was some Mexican but couldn't tell you if the were cubensis or cyanescens.  But it was great!   Let us know your feeling on potency comparison.
