ok, the humidity is low we all agree. I have
had success casing once(third try) and here is how...
cool mist(kaz) with 2 hoses
some h202 in the kaz (10% to 20%)
also perlite in bottom
a wire rack on perlite(more evaporation surface)from the perlite
I also used a drip shield to super-humidify the chamber for when i wouldnt be around for a day.I would spray the shield with a fine mist, this mist humidifies the air. Make sure you have proper water level in the perlite (about 50% but all must be wet at least(i stir it with my hand) the beauty of the clumps of b+ were absolutely awesome and large, i feel they enjoyed the high humidity (3 sources although not always at same time)the birdseed substrate also contributed to their health.
I need to get pics developed soon, 30 shrooms coming out of a single clump, it was hard to remove the cluster,oh well, I dealt with the problem...
