I would still do co2 if you have a higher wattage light. I use exhale bags in my tent with my 600 w chilled led

Hi mate, 30 degrees is not too bad, its on the high end but still a safe temp. As long as your RH is around 55%, you should be fine without AC. Adding CO2 is a great idea. My plant has had high co2 levels from the start and the growth is amazing. She will drink more water though. Im at nearly 1.5 litres every other day. I hope this help, good luck and happy growing

Personally I would lean more to supplementing them with C02 if you are running a strong LED light especially if you are running over 800w

How do you deal with the humidifier in hydro ?So I bought a dehumidifier as advised but now the room gets hotter (Had to setup an extractor to pull the hot air and now I have no intraction) and during the day EC goes up of 0.1 or even 0.2 (from 1.8 to 1.9 or 2). I suppose there are more nutriments because of dehumidification

How do I know my filter is still running ok? can it wear off in just a month?I have a vulcan carbon filter for a tiny tent. It runs 24hrs a day for the last month. Now, the smell coming out of it is not neutral anymore (not strong cannabis), but it is a bit heavy and I'm getting paranoid. How do I know my filter still runs fine? High umidity is a factor?
