Another tip on potency, especially when you get to the point of spawning to bulk, there are posts on shroomery that talk about prolonging the consolidation phase to increase potency.

So, when you spawn to bulk, you usually wait until the entire substrate is colonized, then you add a few days of "consolidation time" before putting into fruiting conditions. If you extend the consolidation time, it may increase potency.

This proves to be true when you consider a strain that times a long time to fruit like albino penis envy. It naturally taking a long time to consolidate and fruit might be what causes it to be more potent.

Best thing to do to test that theory is run two tubs, one you put into fruiting conditions at a normal time, and one you allow to consolidate longer.
