Ants: In Hell, where I live, there isn't a drop of water to be found, except in the plant's buckets & the plant itself. Fire ants drilled and drank deeply from 4 of my Ladies, killing them all. Spray underneath the buckets, and a LIGHT spray on the top soil, AFTER you have watered them. There is 100's of different kinds of ants, all are up to no good in or around your Ladies. Cutter Ants, Carpenter Ants, Fire Ants, Aunt Mary, ETC.,... none of which is beneficial directly on or around the Ladies. For the Guys, piss on'em, but not in the plant containers. 2 Oz's per 1 gal is OK, though. A light sprinkle of boric acid will keep ants away-kill'em, with the exception of sugar/piss ants. They, once waded through a barrier of boric acid, and killed all my Grey cricket's/farm. A Cricket farm is really cool. 2 OZ's of Orange Oil per 1 gal of water will kill'em, naturally IE: natural cause of death, so PETA don't get all hissy. Treat the solution like a plant killer, 'cause it is. Anyway, kill the ants.
WORMS. In big containers, worms is fine. Sea Maiden nailed it, the fucking black nursery bucket literally "broils" your root system, and multi-tasking, also makes Macaroni & Cheese on a good day in hell. A man named Shields wrote THE book on raising Red Wigglers. Check it out at the Public Library. Asked, How do I do it? Drop worms is soil..... Organic growers, only. Worms don't survive dropping LSD, or any Chemical based poison. If your soil is healthy in big containers, they will do you proud. Being the big Texas Rancher that I am, I run about 200,000 head, Earthworms, that is. Just order some on-line, 2 dozen per big container, the rest goes in the organic flower beds.
Wood is one of the best insulators there is. Lining with plastic invites fungi, root rot & mold. No lining needed. Tttthat's All Folks!
