Boy, I'm glad you guys started before me. Based on some of these Pineapple Poison grows, I'm thinking of topping my 2 plants. Seems like these girls like to stretch like crazy.
I've noticed my young seedlings are probably some of the tallest seedlings I've ever grown. And, I even hammered them with my cob less than ~18" from the tops, without negative results.
Keep up the great grows, growers. I enjoy all your posts.
