I have a question. I live on the very dry small Island of Aruba, and I have seen (poisonous) mushrooms here once, after prolonged rains, about 18 years ago. Since then nothing. Water is expensive here. Is there still a possibility for homegrown mushrooms without making a big 'reversed' greenhouse (do not know how else to call it, but something to keep things cool and dark, wich is hefty in price to make and maintain).
