You don't NEED one but it's ideal to have one for sure. If you're going totally sealed, meaning no intake or exhaust except in the closed circuit of air cooled lights and using A/C, you can use just about any Co2 controller. If you were going to run intake and exhaust for the room with a Co2 tank, you're best off with a controller that has fuzzy logic. I just think that you're possibly wasting a fair amount of Co2 with out going completely sealed or at least in fuzzy logic mode.so warlock to run co2 i dont need a controller? i was under the impression i needed the tank a regulator and a controller? this impression was given to me by the hydro store owner so not sure if $ is the reason
No there isn't a real need for the monitor. But it is best to have one. I ether waste co2 or run it light. My aim wasnt to stay at 1500ppm yet. Just to keep it above 800. So I use the co2 calculator and found the best I could. And used the co2 test kit. So when time is just about to turn off I'm around 2200ppm. But 15 min later I'm at 800. This is working well for me but I will be getting one in the futur. A bottle lasts me 8 days. But if I had a monitor I could get 9-10. So right now it's cheeper for me to run with this then getting even a ppm-4.so warlock to run co2 i dont need a controller? i was under the impression i needed the tank a regulator and a controller? this impression was given to me by the hydro store owner so not sure if $ is the reason
I am a first time grower. I don't indulge, but I am attempting to grow for my spouse, who is a patient. I'm a tight wad and dont want to spend the gas and money to drive 90 miles to the pharmacy all the time. Anyway, I have 6 girls under a 4X4 florescent grow light. What can I expect as far as yield goes?I totally dig it. Nice clean garden. Hydro is fun but expensive. I have been teaching patients to grow their own meds and setting up micro and closet grows for patients for years. People need to know they don't need the million dollar high tech toys to grow top shelf meds, just advice and a little knowledge. I have been providing meds for the same handful of patients for free for a while and only am flowering 4 to 6 plants at any given time, not including my outdoor girls, but still manage to pull on average of a pound and a half every 8 weeks roughly 8 to 12 ozs every 4 weeks. Not to shabby considering My flowering area is 5ft wide and 2.5 ft deep and 8 ft tall. and am only running a 400 watt hps. I took down 2 Dairy Queens 2 weeks ago and after hanging for 7 days yielded just under 10.5 ounces dried.
