My feelings 100%Drip rings? They are prone to plugging up, a pump is needed, then you have to monkey around learning to adjust flow rate, timers, ..... cheaper maybe , better? Not on your life! There are enough auto pot users on here now to prove it too. And no, they don't flood. The only user here that had a flood was op error, not the product. The only fault with auto pots is the small tubing. Yet, since switching nutrients I've not had a clog, even with Megacrop's known residue! Just for giggles I ran the system for 6 months without cleaning the lines, not one clog. IMO, auto pots are superior to all but true hydro, and hydro is a fussy pain in the ass, two grows in DWC was enough for me. Auto pots keep your plants perfectly watered and and at a consistent moister content in the medium, never too wet, never to dry, impossible with a drip system! You can top water if you like, but for me, the best thing ever was to get away from top watering and hand watering.
Also, with bottom watering, the top inch of medium dries. Sprinkle some DE on that dry medium and you have a bug barrier, and from what I've seen on here, the qaulity of bagged coco has gone to hell and people are having issues with thrips and white flies, etc from contaminated coco, that would sure help!
Airdomes... i'm thoroughly unconvinced they are worth bothering with, and why complicate such a simple system. Same goes for pumps in the res, a waste of time and money, and your adding heat to a nutrient solution, that's asking for trouble.
Personally I love organic in auto pots! Just add water! What could be simpler.
I swapped to biotabs as nutes when I swapped over to autopots and have only ever put water in the system. Never had a single blockage or leak.
When I first decided I read all the reviews from people stating they could flood etc so I brought a 1.5m2 kids paddling pool and 6 autopots fit inside perfectly.
I changed over to a 200l flexi tank as well and that has a channel under it so if it breaks it floods the pool.
Really didn't want 200l coming through my upstairs ceiling
Luckily it's a precaution I haven't needed it yet
