I thought they were 5 gal but wife remembered me saying that I ordered 3 gal lol. I put my plants one at a time on a wire mesh screen on top of a tub, then I water , let run off for about 15min then put back on its plastic saucer. I check a little later to see if there is more build up and empty if need be. I’m planning on building a 2ft extension to this tent and have lots of ideas for auto watering and gravity drain but fishing season is coming up in less than 12 days and I had to get my boat ready. I installed a floor on the front so needed a bugle pimp and drilled a hole in the wrong spot so kinda takes presidents right now unfortunately. I’m hoping I can get in the garage next Monday to start on this build. My other concern is the only store in town that sells coco coir is out of stock and has been for over 3 weeks. I have perlite waiting. I’m heading to a big city this weekend so I know I can grab some coco there. I would like to go to a bigger pot size but I thought I had more time lol.
