Transplanting 101

Hi Folks: I’m really new to this growing. I’ve got a couple of questions…I need to transplant but when? The white widows are 12" tall in medium sized plastic cups and are doing great! I don’t want to get “Root bound” but I don’t want to take them out of their environment and hurt them. I plan on transplanting them into 3 gallon plastic grow pots. They are all about 12" (1 foot) tall. Thanks for your help.

12" tall, I think most folks would tell you to go ahead and move her to the 3 gallon pot. You shouldn’t hurt her if you’re careful and prepare your hole in the new pot and whatnot.

Transplant now
-good luck

Thanks very much!
