Hi @Skybound I was wondering if you can assist me with a homemade calmag recipe that can be used instantly for plants with about 6 weeks left in flower, in soil, indoors. @InTheShed mentioned that you have a Epsom salt and gypsum recipe.
Hello I was told to get ahold of you as I'am a rookie lol I'm trying to do simple grow first time. I have outdoor green house with hydroponic tomatoes. I want to do weed in pots then buckets in green house. I have a natural spring in my property and would love to use that water or that water threw the house drinking water filtration. The spring is high in iron I'm guessing? My question is what should I buy for water tester on budget. I bought basic top soil no miracle grow stuff. I guess basic info for dummies? I read your mixing your own nutrients post with that other guy and I was lost lol or if you've already done a post for dummies if you could direct me? This my first day
Hey Sky, I should have said I already have a (expensive for what it is) Sentinel environmental controller. I would love to switch to a Pi when funds allow. I have temp and rH perfect after a week of fiddling. My A/C doesn't have a thermostat readout; it's just a knob.
Adding CO2 is my next goal. Those controllers are pricey too. Have you worked on that? I know OpenAG uses off the shelf CO2 sensors, and I'm sure the code is available.
