Yes they are elevated. I might try airpots next time.
man, try SuperRoots Pots, the Zon has them. I tryed the fabs, i hated them. Got ugly lookin, then you can reuse them, but pain in the butt. The superroots pots, come apart easy and can be hosed off and used again for years.
as for Coco, u guys water it to much. The key benifit of coco coir is it holds water and O2, and when the water in the coco drys, its leaves little pockets of air, and the roots love it. If its constantly wet, the O2 in the water surrounding the roots is eatn up quickly, then just siting in stagnit water till you water again. Also, roots like to dry out a bit, and search for water, so if its always wet, they dont need to search/grow for water.
Try it on 1 pot of coco, and only water when its 75% dry by weight. You need to learn this technique of water weight. Grow boss has a video proving this also. Very little water evaporates over even days of sitting. Granted its plant free, but even for tiny vegging plants, there is no need to total saturate the pot multiple times a day.
And ive even heard very productive professionals on coco, to let them dry out to 25% of weight. and if your super scared about your coco going dry, add biochar to it. i actually think all grows should be using biochar to be honest, just as a safety net incase your watering system fails, it will give them a life line for a couple days.
I use cocoloco, and i can let them dry out almost completely, and they still dont droop. Cocoloco is more of a promix, coco/perlite/peat.
I will post an weight experiment in the near future of a plant in a solo cup.
