Hey Sam, there's really nothing easier than the Jack's Classic nutrients. For the Blackjack grow I just used a two gallon watering bucket with two tablespoons of Jack's per bucket. Two gallons was usually enough to water all 6 plants everyday. If the weather was really hot, I would use 3 gallons. But the amount of Jacks was always 1 tablespoon per gallon. The feeding schedule was usually once a week, but sometimes I would do it twice a week. In veg I used the 20 20 20 Jacks and in flower I used the 10 30 20 Jacks. About once a month I would give them a mid week feeding of either Superthrive or Sea Green just for the heck of it. All of the plants were grown in 5 gallon cloth bags that I bought from my local hydro store.
I kind of gave up on growing in hydro, because it's too problematic for me. The real problem is that I don't have a way to control the temp in the grow room. I have central heat, but no A/C. So when the days get really hot ( And for some reason the last few years have gotten really hot in the spring and summer.) the plants pay the price. This spring I did a grow of the same Blackjack strain and it was the worst grow ever. In mid spring we had several heat waves that lasted for several days. The water in the DWC buckets got way too warm and the roots just started dying off. Even after the heat waves were over, it was just too much for the plants. I got about 6 oz of smoke, but the rest was just dead. So for the summer grow I went back to soil. It seems to handle the stress better and the pots don't get as warm. If the days got really hot, I would only run the lights at 1/3 power. That also helped a little bit. So anyway, it's soil from now on. The soil I used was mostly Happy Frog and I added some of the soil I had from my outdoor grows as well. It's a bunch of different soil mixed together, but it seems to work OK. I've never grown in coco, but I've watched others do it, like
@gr865 He seems to do fine even with his CMH lights. But he also puts a ton of TLC into his grows. I think I've seen you commenting in his journals, so you know how much works he puts into it. But his grows are always stellar. But for me, it's just too much work to grow in coco.
