Hi @urbangroove! I can see your night temp is pretty cold, whereas your day temp is quite hot, the gap is impressive! It makes me think that your setup generates too much heat, mostly because of your lamp, and also a poor airflow. How do you extract the air out of the tent? Do you have an exctractor? If yes, is it connected to a thermostat? What are the settings for the thermostat? I guess the room where you did put the tent has a decent temp, but the air remains captive inside your tent, so try to improve your airflow, and put a tiny fan blowing a continuous breeze onto your lamp in order to cool it down. Another option would be to put some iced water bottles in the tent every morning, but this is time consuming and lasts only a few hours. You should also increase your relative humidity, in veg the best is around 65-75%. Finally, consider going with LED next time, the new models are pretty impressive, my QB setup generates almost no heat at all. Hope this will help, keep us up-to-date and happy growing πŸ‘Š

Eh a few things can do it like getting an ac unit to make it colder. But otherwise if your temp outside the grow room is cold your exhaust can bring that in, or itll all come in the second you turn off your lights or dont have a heater running. Id say just avoid running at 60 degrees constantly as thats where pm and others thrive and can contaminate the plant. Nice grow, happy flowering. ✌️

Your temperatures are current at 84F and that's pretty high so you will want to lower it. You can do this by adding more exhaust to cycle the air faster or by raising the light. There are other ways such as buying AC unit. You absolutely want to lower those temps tho.

for such a strong light you need a BIG fan, try a 1300m3 125W silent fan on max power through a cool tube.

Hello @urbangroove ! The absence of energy πŸ˜ŽπŸ‘Œ. If you wanted to ask how to lower the temperature then you don't have many options. An expensive option is to use an air condition and a not so expensive and what would i do is to use an air cooled reflector. If you set it correctly you can drop the temperature around 3-5 Β°C. If you can't do any of the above then just raise the humidity around 75% ( it will help you with the high temperatures by lowering the transpiration of the plants but only at veg stage ). Happy growing ! πŸ‘Š

You can do quite a few things to help reduce the amount of heat in your room , firstly you can adjust your fans to exhaust harder in order to get rid of the hot air thats around , secondly i would advice that you exhaust straight outside this way no hot air just circulates around making it stale , you could also have windows open close to your room so that fresh air can be taken in by the intake which will result in lower heat , raising your humidity will bring down your heat as well the moisture in the air will help cool it off . You can get cool tube reflectors that are air direct cooling for your lighting making it so you're light runs cooler allowing you to get it closer to the plants , you can stick an AC in the room your growing in for your intake to suck up the cold air . You have sooooooooo sooooooo many options . I would advise doing a little bit of research to see which method will work best for you . I hope this information helps you understand that you have many many choices to choose from to help cool your room down . Over all your not in terrible shape i would just raise the humidity first and see what happends from there if its not enough then start looking into other options . -Happy Growing! =

If you mean how can you lower them then there are a few things you can try: turn your lights on during the night, specially during flower; increase the exhaust fan power; use AC; use chill packs on the reservoir to keep the water cool and avoid root problems; use a cooler for DWC as they are insulated; use a cooltube with your HID. Hope that helps.

Iam not quite sure what you mean, but i think you will lower your temperature=?You can do a lot to lower . Put you tent in the coldest room in the house that you got. Give a good airflow, open the tent if the lights are on. ( if its outside cooler). change to LED lights, Get an AC...... i hope your water-nutrients solution is colder , if not you will get bacteria problems( root rotting)if that is not what youve asking for, try to formulate anew question
