yes thats what I was thinking. Would these work best for soil or 100% perlite, use it as a hempy bucket?Yes they would work. The best part is you could bottom feed which could help prevent overwatering.
A mix of coco and perlite or perlite on the bottom then coco on top?I am biased, but coco and perlite for the win!
And still water from the bottom or top till res fills up?80/20 coco perlite mix.
ok, so would I refill the bottom every time it dries out or let it dry out then wait a day and refill?It depends how much you let it dry out. Probably bottom.
so top feed to get runoff into the bottom. Then when it dries up. Top feed again. Or top feed then drain the bottom and refill with fresh water/nutes?I would top feed to get saturation, then bottom feed to maintain. If you let coco dry out too much between waterings it can be tough to get it to re absorb. Thats where the bottom feed on that pot would kick ass!
