I have to check mine every 3-4 days to mix nutrients, but I visit the girls daily most of the time. I use 18 gallon plastic totes as reservoirs . . . timers, pumps and drip lines to feed multiple times daily; platform drainage trays for runoff plumbed to the basement sump.
Personally, I use a lot of FloraFlex stuff . . .drainage, pots, caps, tubing, etc.
Nutrients are a whole new can of worms . . . first I don’t recommend organic nutrients. Fine for a soil grow but not hydro friendly in most cases . . . reservoir pH management can be a nightmare, clogged drip lines are common. Not so much an issue with the coco as with the nutrient storage and delivery systems.
Unless you want to use organics because they are sustainable and better for the environment . . . they are NOT better or healthier for your plants in any way. Plants uptake nutrients . . . they don’t care if they came from a chemical or natural organic process. In fact the stage specific NER that you can achieve with chemicals generally allows for faster growth and better yield.
I have used the same nutrient line since 1993-94 when I got interested in hydro . . . General Hydroponics Floraseries, CaliMagic, Armor Si, Rapid Start, Diamond Nectar, liquid KoolBloom, Floralicious Plus, Defguard and powdered Yucca from RAW at the moment. Started with just the base trio and Botainicare CalMag, the rest I’ve added over the last 15-20 years or so.
Plenty of nutrients to sort through out there . . . General Hydroponics has just been doing the 3-part base longer than anyone else. Jack’s has been around a long time also . . . they were well known for Peter’s Pro and a few other products before Jack’s 321 caught on.
