answered grow question 4y ago
At this stage, I would go with 24 to 30 inches, as they grow you'll be able to bring the light down to 18 inches.

Hello, I am using a viparspectra par1200 which has the veg and bloom adjustment knobs on autoflowers. My question is, should I only be using veg during veg and bloom during bloom? Or can I just turn that sucker on full blast the whole time? Thanks

General question about raising lights.
Gotta question for what most of you are doing to raise your lights? Currently I've just set it static and move as needed. But I'm curious if anyone has a easier method or know of anything made to aid in the raising of the LED light fixtures ?

Plug timer running fast
My plug timeris running about 10 fast each 24hr. And is now at about 2 hours past the actual time. This causes the light cycle to shift forward slightly everyday. Should I set it back to the correct time, leave it be or buy a new one? It is plugged vertically in wall socket.

Fan vs Fanless LEDs
How effective are heatsink LEDs? I'm not sure if I should go with fanless (like Mars Hydro SP150) or with a fan (Mars Pro II Epistar 120). I struggle with heat, when the tent is closed it gets to 29-30 degrees with humidifier in full swing (HID lights) and I want to close it soon

Lights airstone c02
What light to plant distance would you set it at? The only test I've done is at 25 inches its stable at 80°f and 75% humidity. When I lower it to 18 inches, the tent read 85°f and 73 humidity. Other question I have is what's your favorite air stone(disk)? Lastly, add c02 yes/no

Should I lower the light?
So, this is her 24 hours after she first came out of the soil. I am trying to follow 18-6 light cycle. The height is two inches. Does she look a little lanky to you guys? Should I lower the light a little bit?
