Coco in a greenhouse

I will be growing in a 12x26 poly tunnel six pot plants and about 30+ other tomatoes,peppers,etc... Smart pots, drip irrigation, and I'm thinking of trying the KISS method. Originally I had planned to do a tlo soil but I went over budget on my truck and am low on play money. Coco seems like a cheaper option. I've never used coco and would like some input on whether this is a good choice of growing medium for my setup.

Also, if using the kiss method, alternating water, flora, water, flora. This drip setup will only be for water, I will have to hand water nutes. My water is ph 7.3 I won't be able to adjust the ph, just a chlorine filter before it goes into the drip system. Can I add anything to the coco to help my ph?

Get another reservoir for fertilizer and T it into your drip line, just use clogless drip stakes. Ph neutral water between feedings is fine. Hand feeding is not KISS because it's not easy. You can definitely afford worm casting and dr earth to mix in so i recommend that. Coco is great for indoor gardening because it gives you total control and it's clean, but that doesn't really do you a lot of favors in a greenhouse. I've used coco in the greenhouse and it works great, like really great! But it definitely wasn't as simple as soil. Not to mention liquid feeding is more expensive in the long run than soil, tea, and finally liquid fertilizer near the end of your run.

Also if coco goes bone dry once you have roots growing it's pH is shot, so god help you if you miss watering on a hot day. I recommend mulching.

Hey thanks man, I'm going to be putting a lot of time and effort into this season and don't want it ruined by overlooking small details that matter. Like forgetting to water and your ph swings....maybe I'll looking into an organic soil. Thanks for the heads up.
