The ideal temp when using co2 is 85F and co2's ppm = nutrients' ppm is recomended by most pros. For instance; this week you feed your plants at 1200 ppm of nutrients solution, you apply 1200 ppm of co2 and so on...
cnd411 Reviewed by cnd411 on . Temperature and co2 I know the ideal temp is about 80 degrees, but should you use a higher temp if using co2. And if so what would anyone suggest. I have read somewhere that 90 degrees is acceptable with co2. Rating: 5
