DWCHCanswered grow question 5 years ago For bloom, a 1+1 mix of tarantula and piranha from advanced nutrients, recommend the wettable powder as opposed to the pre mixed.. over a billion count per gram on the tarantula, and a great selection of myco in the piranha. I'd mix in dechlorinated water, but not RO, with a touch of powdered egg shells and molasses.. keep at 20 deg C or 70F until strands of visible mycelium are visible in the water. Aeration helps speedup colonization. Add appropriate amounts to your solution... Cheers!
