Not really it is a good way too learn different things about different strains. Like some grow into tree’s some are bushes. Some take more Cal-Meg than others. My first LED grow was crazy I had 7 different plants giving me hell and is still one of my best crops…
I was dealing with mold too. A lot of people in my neighborhood got a little mold.
My 1st grow with LED. Guy at the store told me I didn’t need an air flow. I went up there and they already got rid of him…
