Hey @Joe!
Glad to hear we are on the same page :)

1) Yes, you're right! Moving from pf-tek cakes to Spawn2Bulk + top layer (casing or pseudo casing) is a game changer in increasing yield.

2) When picking clusters, small shrooms/pins come together with the whole cluster, it's fine.

3) Regarding the height of your mushroom cake (grain spawn + bulk substrate + top layer) it should be within 5-10 cm (2-4 inches). +/- 1 cm is not critical. You don't need a tower, at the same time cake should be thick enough.

There is also one more recommendation. Your cake should take up no more than 1/3 of the volume of the fruiting chamber (shoebox, bottle, monotub). For instance, if your plastic box = 24 cm in height, then your mushroom cake should be up to 8 cm (24/3=8).

So, all the options you've listed above are right.

Don't afraid to make different cakes (different S2B ratio, different height etc.) and compare results.

Good luck! Waiting for good news from you 🤞

Hi Shroomok!

yeah you got me right It's like you suggested: I have 440ml (sorry metric here) cakes based on rye berries. At the beginning of my growing approaches I directly growed from the cakes, currently I switched to slicing the cakes and putting them into coco coir mix - my rye berry based bags (~2 KG) unicorns look great and should be ready soon. Bags seem to colonize very well and I am about to quit the cake business :)

So: I will try a 1:2.5 and 1:3 ratio and MIX the stuff. The top coco layer sounds great.

A little negative side effect I currently experience from using the "sliced-cake" method is that the shroom clusters are pretty tough sticking together and I "accidentally" supercarefull-harvest "small bystanders". I was a little bit more flexible and could be more selective when harvesting from the cakes directly.

I have one additional question:

Whats the ideal filling height of the 1:2, 1:3 mix + the coco topping ?

I wanted to try, please correct me if dead wrong:

4 cm MIX + 1cm coco topping
5 cm MIX + 1cm coco topping
6 cm MIX + 1cm coco topping

have a nice day!

Hi @Joe! Could you please clarify? Do you mean you cut BRF (brown rice flour) cakes for slices and then cover with bulk substrate (coco coir mix). If so, yes it works great and much better for fruiting than PF-tek cakes.

After full colonization wait a few days more to make sure grain totally covered with mycelium from all the sides.
1:2 or 1:3 ratio is up to you.

You can use "substrate-layering", no problem. I prefer to break up grains to separate sticked grains and MIX with bulk substrate (coco coir mix). In this way we create more points of growth. Therefore, the speed of bulk substrate colonization is faster. Also I highly recommend to add 1/2-1/3 inch (~1-1.5cm) of bulk substrate (coco coir mix) on top of your cake after mixing.

Let me know if you have any additional questions.

P.S. Hope I've got you right :)

Hi, I am just switching from cakes to bags. I had quite success with cutting the cakes (2-3 cm slices) and placing them on coco bulk and cover the slices also with coco (40 x 60 x 7 cm). Looks great and smells great so far, 0 contamination etc.

So my bags are ready in a couple of weeks and I was asking myself if I should "mix" the bags 1:2, 1:3 with substrate or if I should try to cut the bag-blocks similar to the way I proceed with the cakes.

Does anyone have experience or recommendations with "substrate-layer" instead of "substrate-mix" ?

Делаю Spawn to Bulk в монотуб. В период колонизации (когда все отверстия закрыты и нет воздуха) нужно монотуб држать в темноте? И какую температуру держать и влажность в этот момент?

Hey @Dude we have 2 main periods in mushroom cultivation: colonization and fruiting.

We use styrofoam box as an incubator for COLONIZATION period (to boost and speed up mycelium growth on grain substrate in jars/bags). We don't need FAE here. We need FAE for FRUITING period in fruiting chamber (i.g. growbox or monotub).

You can learn the difference between an incubator and a fruiting chamber on this page at the very beginning ;)
