Grow tent Temperature

Newbiegrower420started grow question 4 years ago

I have a 90cmx90cmx60cm grow tent with a VIPARSPECTRA 300W LED Grow Light inside.. How much will an extraction fan and carbon filter bring down the temp inside? In this heatwave my tent is running at 33 deg C, no plants seeded yet. Will the fan be enough or should I get a cooler?

Hey there ! So the optimal max temp is 25/26C Basically the main idea is that it will be hotter inside than outside. So what you need is fresher air outside for the intake this means that it's difficult to reach the correct temp if the outside temps over 25C ... My point is that the fan won't be enough . Beyond that you just have to tinker to get it right. One thing you can do is to get a small "evaporative cooler" which stabilises the humidity on 50% and the temps at 25C . Hope this helps ! 🚀

It really depends on what the temperature is outside of your tent. If your temp outside of the tent is in the acceptable range, an inline fan should save you! It's still a good idea to have one either way though. Terrabloom makes some really nice ones on the cheaper side. I recommend a 6".

Do I really need a exhaust fan ?If my 2x2 grow tent sits at 26c and 68% humidity without an exhaust fan do I actually need one ? The top of my tent, the vent is open and I’ve opened the observation window at bottom to allow air in. I’ve two fans, one at canopy level and one in top corner opposite the top vent ?

Humidity issues near flowering So I installed an intraction (145 m3/h speed1) and aluminium foil on the pots but humidity is still hight like 75% when nightime and the lowest is 65%. Probably the water evaporates by the pots (drip, clay pebbles). I have no more ideas. Do I have to buy a deshumidifier? Thx !

Ventilation Setup for Smell Attenuation Is this setup ok? Since the air tent will be recirculating i think the smell will be atenuated. I haven't seen other growers with this setup (I'm a newbie though), so I wonder if there's something wrong with it.

is this dehumidifier bad?Hello! I'm just wondering if this sort of dehumidifier is somehow harmful to our plants. The fact it has a tablet and that it claims to remove 70% of smell let me suspicious.

Humidity won't go down because of clay pebbles ?Though my extractor is at high speed, I have a hard time with controlling humidity, I hardly go under 68%, specially during the night. Probably it's the clay pebbles since the pots don't have a lid. I placed the temp/humidity probe near the tallest leaves. what do you think ?

Ventilation setup Do I need more than just carbon filters and 2 fans in my 18"×18"×48" grow tent? I bought 6 inch round carbon filters that are about 1/2" thick. And put them in the vent holes for odor control and I have a hanging fan at the top of tent and a small fan for exhaust. Is it enough?

Anyone tried a plasma filter instead of a carbon filter?Supposedly superior odor elimination over carbon filters Look here. https://www.youtube.com/watch?v=kwiNUkjL1Dk As you can see they resemble carbon filters (they're part carbon filter actually). The only question is...can they run 24 hours a day for 3 weeks? Anyone tried them?

Can a carbon filter be too "big" for an exhaust duct fan?Is it fine to use a carbon filter that can handle twice the capacity of the airflow my fan can produce? Or will the fan have trouble ventilating the tent then?
