I currently have 2 mycobags colonizing... and in about 3 or 4 weeks when my "other" grow is complete I will have two 100w blackstar led's sitting around doing nothing... would one of these be a suitable source of ambient light to induce fruiting???
Actually they like the blue end of the spectrum. Your 100 watts are overkill, if you really really want to use them, then expose your ready to fruit substrate to about a minute a day.
