Is there a recommended next step after doing BRF tek? Monotub? If so, what tek should I try?
I continue to research this topic and here is one of the popular teks for monotub that was compiled by wharfrat a few years ago.
Beware that some have found that the coffee in this tek can promote contaminates and from what I have read you can just leave it out.
More to follow as I find them.
The next step after PF cakes would likely be dubtubs or similar.
Monotubs are big. They yield a lot but one failure wipes out lots of spawn and substrate. Not only that but you're left with a large pile of just one variety, that's fine if your selling, host mushroom orgies, or just dont mind monotony. With dubtubs you can cheaply grow medium size crops of a range of mushroom varieties. Dubtubs also use the same size pressure cooker most people buy for doing PF cakes [large enough to hold 4 pint jars or 6 cake jars], people can spawn monos with pint jars, but most seem to prefer quarts.
As someone who never sells, likes variety, and sadly doesnt host mushroom orgies I doubt I'll ever do a mono.
Maybe this will help if you're a visual person (minus the heat pad, 9:38 for results). PE prefers mono/dubtubs, expect slower colonization and fruiting times. Also expect approximately 2x the potency compared to other cubes like GT and B+. Good luck!
Thank you all for your help. I'm somewhat limited on acquiring new resources at the moment but I want to follow in the spirit of what has been suggested--so I ended up experimenting yesterday when I went to dunk my PE on BRF cakes for a second flush.
My first flush yielded just under 2 ounces of cracker dry fruit, the most potent I've ever had. So I'm not experimenting out of desperation, but because I can see the PE-on-BRF moisture retention issues with my own eyes even as I harvest a more-than-expected amount.
I had twelve healthy cakes. I dunked them for 22 hours. Placed eight back into the fruiting chamber to follow the same protocol as before. I broke up the remaining four as gently as possible for use in a mini mono tub. I made pasteurized substrate from verm, sphagnum moss, and gypsum, layered the substrate, then crumbled PE cakes, then substrate, then cakes, then substrate. Set it up to colonize. I decided against adding a casing layer. If I have issues with the mini mono tub, I'll try a casing layer (and maybe replace peat moss with coir) using four more cakes when I dunk for the third flush.
I understand that PE and APE do well on grain, which is what I'll be using the next time I grow either. Is grain optimal for others too, such as Golden Teacher or B+? I like to keep things as simple as I can, so using grains for a lot of my psilocybe grows is appealing.
Pictures of the mini mono tub experiment will be forthcoming in about a week.
I've peeked and white mycelium is visible in patches across the entire substrate surface of the mini mono tub that I set up with pasteurized substrate and four of my PE on BRF cakes crumbled. The tek I'm following says allow 7-10 days for colonization BUT it calls for spawn on whole grain. Also, my four BRF cakes have already been through one flush. Will 10 days likely be sufficient for colonization considering the difference in my grow? How do I know it's ready for fruiting? I'll have photos posted on Saturday, so if it's a matter of knowing what to look for, the evidence will be on display in a couple of days.
With the eight remaining cakes, I've started dunking every other day at least, using the most sterile conditions I can manage. No signs of contamination and it's addressing the moisture problem that misting can't touch. Some of these PE's are getting huge, so the new problem has become supporting them so they don't break off from sheer weight. Needless to say, I'll be pursuing a mono tub set up for those cakes as well.
