I'm doing really good this year and still have 3 weeks or so to finish swelling. I used 2 5gal buckets for 2 and the other 4 are right in the ground. I'm happy with the out come but I'm stepping up to 2 20gal kiddie pools and the other 4 I'm putting in 15gal grow bags. I'm a fan of pro-texk and kelp4less . I've been reading a lot so I think there's going to be some changing with them also or others added. Just going to step up a little . Can't wait for the out comes this year also.
