    Recommendations for tiny AC units? 2x2 tent and environment reaches 45+ degrees C.

Thanks to this forum my current ongoing Autoflower is absolutely flourishing but as the title suggests that's not why Im here today. Aforementioned Auto is 3 weeks away from harvest and...

    Root Zone Temp too high for LED Co2 grow in Rockwool, what to do?

    So I just switched to LED and from what I understand plants like much higher temps (85-87F, and as high as 96F with co2) because the leaf surface temperature is substantially lower with LED (lack of IR) when compared to HPS. My room is currently Phase: Week 1 Flower (Just flipped 12/12)...

    Temperature issues

    Just got my tent set up and the temperature is 18 Degrees Celsius. Is it okay to grow at this temperature? Using led lights so not much heat from the lights and don’t want to invest in a heater as they are very expensive to run, is there any other ways of raising the temperature?

    Recovering from stunted growth

    I believe due to my daytime-night temperature fluctuations in my indoor garden, I’ve stunted the growth of my two Magic Melons. I’m in the process of adjusting my ac unit to try and correct this but does anyone else know if it is to late? Can and will these plants recover? I’m on day 22 of veg...

    Exhaust fans as a means of temperature control

    I’m using an AC infinity 6” fan in a 4 x 4 tent which is a fairly high end fan with probe and controller etc and definitely an overclock for a 4 x 4 as I originally got it as a top end fan for a 5 x 5, I get the importance of an exhaust fan to control odor mainly but secondary as a means to...

    Direct Sunlight vs. Temperature

    Hey, I live in a very hot part of the world. Direct sunlight comes at a cost of 38°C (2PM - 5PM) After 10AM temps cross 30°C and don't drop to below that till 9PM. I've been giving the plants direct sunlight till about 1PM (35°C) and misting them. Then moving them inside with air conditioning...

    I live in the mountains of Colorado. Temps outside get into the single digits at night. I'm having a tough time keeping my night temps in my grow room above 60 degrees F. It has fallen to 50 a few times the last 4 days. It stays around 75 during the day. The grow rooms is in the attached garage...

    LED temps

    I’m new to growing, but am very excited. I’ve been doing a lot of research and decided to use LED but am finding some conflicting info on temps but this seems to be the most intelligent article I’ve found thus far... “When a leaf absorbs IR, it heats the leaf creating actual leaf temperatures...

    Temp fluctuations from 68f-86f in flower bad?

    okay so my plants are a little over 4 weeks into flower and i only have one plug in the room which is next to the radiator which turns on and off periodically throughout the day. (so i cant move my tent). When the radiator turns on I plug in the exhaust fan but only for about a half hour because...

    Upsizing my grow but worried about temps

    Okay so I am currently growing in a 2*4 tent and will soon be upgrading to a 4x4 or 5x5 tent. The tent I currently have is inside the house so the temps are pretty easy to control ( when it's hot the AC kicks on lol) but the big tent must go into the garage (unheated and uninsulated) now I have...
