Yeah, I've had a love affair with coco for years. Used to do soil and never produced anything stellar. Was alright product for a young grower but wasn't anything great either. I switched to coco when I turned 20 and used it till I took a break from growing a few years ago.
Still getting back into the grove but a lot of things changed in the time I wasn't active. Those are the product of my second run since being back and I've already determined I'm going to have to automate the waterings. I simply do not have the time to feed them like I would like, which with coco is a big deal.
The more you can water them, the better they'll do and more they'll produce to some extent. 5 times a day, watering for 1-3 minutes each time would be the bees knees, especially in a small environment with high plant counts. This run would've been much better if I had the ability to automate. That and not having any humic or fulvic acid around is kind of a kicker. But next time I run a sog in a space like this, it will be with different, better suited genetics and fully automated.
This solo cup run has definitely been educational for the capabilities of coco as well as the plants but I believe in my case, the tight confines have impacted overall yield as well as the lack of ability to water more frequently. As it sits, they get 2 or 3 waterings a day depending how busy I am and that alone isn't enough. 5 times a day and things would be retarded, in a good way.
Didn't mean to thread jack, just thought I would give a little perspective for coco.
