I had a room filled with plants in 2005. It wasn’t much work at all. My epic fail was drying. Drying is the hardest part. I had 5 pounds of moldy ass weed my first harvest. Was a horrific failure. But the growing aspect is not difficult at all. I had a 1000 HPS. Had 12 huge plants that produced perfect buds. It’s a very fun thing to do. Especially when you see those white hairs pop through and you know you have females.
