Go deep young sir, they lie when they say it doesn't matter.

But 2 1/2 ' good job.
tlranger Reviewed by tlranger on . What's a good depth to make my outdoor patch? Hi, I was just wondering if anybody had any good tips or ideas of how deep I should go, or rather, what the minimum is to have a good depth. I'm trying to get all my plants in the ground by Friday. So far I have a patch about 10' x 6' and about 2 and a half feet deep, and my clones are about 15" tall. The strain is Jack Herer. Any advice would be greatly appreciated. Thank You, Mohammad Rating: 5
