Hi guys, I'm new here and after reading a lot before without posting it's time to get started myself as well. I'm already growing for a while under HPS and now decided to start using COBS as well on the side. So the basic thought i have is this. I usually tend to grow under 1200 watts HPS...

So I just got an HLG Scorpion Rspec 600w. I let my plants get a bit too tall for my tent. Well... more than a bit. My light needs to be like 12-15 inches above the canopy, but that puts my light pretty close to the top of the tent. So, my question is this: Will the light or the driver of an LED...

I currently have a 300w viparspectra in my stealth grow cabinet. (Dimensions: 15”w x 26.5”d x 50”h) But the efficiency is trash, and it produces a pretty good amount of heat. I used this light to veg and flower, so if possible I’d like the new to do the same. I’m sold on upgrading to a new...

I’ve posted before about my stealth grow filing cabinet. Currently using a 300w viparspectra but after hearing about new LED lights such as HLG and what not, I’m looking to upgrade. However being in a filing cabinet, there is DEFINITELY limited vertical space (I want to say the overall height is...

I’ve flipped my plants just over 2 weeks ago to 12/12 and the humidity has went pretty high in the 70s-80s, I have a small dehumidifier but it’s not really helping much any other tips to what I can do, do you think I need a better carbon filter set up??
