heat

I have a pretty small tent (36x20x62) and a 600w HPS dimmable glass tube cooled hood. One 240CFM fan blows outside air through the light and exhausts out the back and another 240CFM exausting heated air from the top of the tent to outside. My outside air temp is 74°, bottom of tent air is...

Hey guys, Im growing for the second time, last year I started in March 23 and harvested June 25. Im proud of the result, it was not as strong as the stuff I bought from dealers but it was quiet good. My impatience did it. This time I started June 23 and Im running into some problems. The...

I read everywhere about air temps. And although we are heading into the heat of summer it made me consider the winter months for those of us in cold climates. For my indoor grow if the floor of my grow tent is chilly say in the 60s would that affect the plants by wicking heat out of the soil...

I have some trim I put in a closed container for a few days to make butter out of, but when I opened it I noticed a little white fuzz on maybe 5% of the whole thing of trim. My question is can I still make butter out of it, will the heat kill anything bad in it and if not the heat of melting and...

I noticed when I put my thermometer under the light on the rims of my "pots" that the temperature is way higher than if I clip it to the side of my hood. I reasoned this is because of the direct heat from the light, but the question is, is the temperature in the light more representative of the...

High everyone! I have a new grow tent (see image below). I also have a carbon ventilation system to install. Which ventilation holes do I attach the carbon fan to, and where would I put a clamp-on fan to keep the CO2 circulating? Also, as the grow tent will be kept outside in a wooden...

Hello, I'm working on my second grow. I have three bag seed plants that are half indoor, half outdoor plants. Not sure what strains they are, but they all seem different. Looks like two sativas and one indica. I put them outside to absorb as much of the natural sunlight as they can. I put...

Hi all, my two weeks old Nothern Light auto looks ill. I use a 300W dual spectrum CFL. So far I'm trying to bring down the temperature with ice and a computer fan. Still, cannot decide if it's the heat, too rich soil or overwatering that does this. Any ideas and suggestion would be appreciated!

Making a grow box, is this going to do the trick? Will have 2 MarsII Hydro 300 LED's. Hoping to trap the heat the LED's make in the winter. Gets down to 40F in the house in the winter at times, and I figure I could always have one on, and alternate between the 2 to keep the heat going. Let me...

Hey all, My grow room got warmer than normal last night and I think my plant is showing heat stress. The plant was leaning over to one side so I propped it up with stakes. Does it look like heat stress? I move the lamp (150w HPS) up a bit to 8" above the plant. Checked surface temps...
