I have heard of wharehouse grows. Have you heard of them?
1000 plants are not uncommon my friend.
Your on the internet now, Google it!!
Peace
Maybe for flowers but who is doing this just to select a few good plants?
You think the plants grown in these grows you speak of are top quality or do you think they are beaster grade buds?
You also think these grows you speak of are popping 1000 plants from seed? Nobody paying production cost on a warehouse grow is going to run a commercial grow from seed, a few herms in the crowd and the whole harvest value just dropped.
