I’m 3 weeks into flower and thinking of getting a air con .. Does anyone have any suggestions on...

Hello! I`m quite a new grower, really new actually. I have a 120cmx120cm tent with a 600w HPS bulb! But now, at summer its generating a lot of heat, even at night (when I turn on) Some days getting 30 degrees. My question is: There is a way to reduce this heat inside the tent? I use to open...

Hey guys, As the title states I'm currently having some issues with maintaining the appropriate temperature ranges. I'm a grower from Malta and we recently passed the law to be able to cultivate up to 4 plants. In summer temps are ideal but during the winter I'm having some troubles... My...

Hi, I started auto white widow a week ago. They all sprouted. The 48x48x80 grow tent is in my bedroom and my tent temperature is always 10-15°F lower than my room I'm guessing because of the humidifier. So I knew I had to get a heater since my room is getting pretty hot just to keep the warm...

First grow, plants are coming along nicely. However its freaking hot in my room, 98-100 and that is with 2 portable ac units blowing in. the ac units are not pulling air from inside the grow room, they are in the other room. I think the ac units are creating a positive pressure issue due to...

I currently have a 600w hps running in my closet but only running at 200w and heat is still an issue , I have about all the ventilation /airflow that I can rn , so am thinking to Change to LED but don’t rly wanna sacrifice yeild / quality if possible , I also don’t rly wanna bankrupt myself On a...

Ima start by saying my grow is in the Center of my house and I have got about all the ventilation I think I can have (room is about 4ft x3ft x7ft), that being said my light on temp is 29c (84f) that’s even with a cool mist humidifier in the room Which tbh idk if that actually helps , but my...

Hello all, Ive been around weed for as long as I can remember but this is my first grow fully by myself, and my first time posting on this site I learned a lot about growing on this site 5 or 6 years ago, but when i finally went at it recently, i was surprised that i'd retained no information...

My tent is 88 degrees with my new light. My plants look good besides two yellow spots on two leaves. I’m guessing they need calcium. I haven’t feed them anything besides water I’m the last week because they just recovered from nitrogen toxicity. I’d like to know if I should get a intake fan...

Ive moved them from my t5 at room temp to my growtent with my mars hydro tsl2000 with 4 inch duct, tent temp at 30-31 and i got some co2 to help them to support heat but still leaves are down ... why? Should i got an AC?

This is my 80*80*180 cm tent and this time of the year its around 27c outside. Inside the tent was 32-34. I found a temporary solution cause im nearly 3 weeks away from the harvest. I covered the tents door with some fly net . Its still around 29 inside the cabinet but its better than 34. Do...

Total newbie here. I have set up a 48”x24”x60” tent with a king plus led 1500watt light and a terrabloom 160 cfm in-line fan. My ambient temperature in the room is 22.5 - 23 degrees Celsius. The temp in the tent with the light on is staying at 26.5-27 degrees. I have the tent flaps open on...

Hey everyone, I recently came across a file cabinet for free and have overhauled it into a space closet. The dimensions are 18”x28”x60” it has intake + exhaust and an extra fan to circulate air. 300W led light, insulated walls for noise reduction. my main question is what temps are okay for my...

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...

My growroom is in the garage and im exhausting all my air conditioner heat into attic space above the growroom and out a roof vent with a commecial cooler fan. Im planning on flipping my 8x8 this summer and adding the heat from four 1000w hps cooltubes into that space above my growroom. I have...

I flipped to 12/12 yesterday and flipped the switch on my 2 LED panels for bloom... Temps quickly hit 90. I re-routed my exhaust to the outdoors and after my first 12 hours in my tent the temps seemed to have settled around 85... Is this too high for indica strains indoors? I keep the house...

Hey guys im wondering about the type of cooling needed for 560mm Bridgelux EB strips at 19.5v 700ma. I've heard from some that they require no cooling, but i would rather stay on the safe side, so what type of cooling options can be had for cheap for these strips? And remember.... Cheap. Thanks

Has anybody noticed that specific brands or types of HPS bulbs put out less heat than others? I'm running the following in a 3' x 3' x 6.5' tent (Exact measurements are: 39" x 39" x 79") with a 315 CFM exhaust fan and passive intake. I'm just using the mesh intake vent at the bottom of the...
