Light distance for seedlings

Autogrowzstarted grow question 4 years ago

I have a 300W Mars Hydro light LED. My plant just crawled out of the dirt a few hours ago? Is 23 inches a good distance away for the light? Thanks!

according to mars hydro website.. 24" is what they recommend for seedlings so I'd say that's perfect in week or so once you get some foliage going lower down to mars hydro recommended veg height of 18".. I'd consider running a bit closer like 16".. Then anyway for flower you wanna keep it a bit closer Mars hydro recommends 12".. With a light of that power I might even try 10-11" to maximize yield output from light source...

Hey Growmie, I would say yes, the company suggests 24"-30" inches for seedlings so I don't think the one inch will matter too much. If you notice any signs of stress just back it off a few inches. Hopefully, I answered your question and remember ..."Happy Growing" and "Free your mind one puff at a time".

Which of the two options do you choose and why: Option 1: 1440w over 40sqft giving 36w per sqft Option 2: 1440w over 48sqft giving 30w per sqft. The difference is an extra 2x4 of grow space. Do i go for more lumens or more plants? This is my first LED setup

Grow lights I'm currently looking for a new grow light. But it's crazy how many choices there are. Since my grow area is very small, 40x40cm or 1x1', I don't need a lot of wattage. So would prefer to invest in quality over quantity. Any suggestions?

Seedlings Woke up this morning and she’s grown a bit from yesterday. 4cm tall now. HLG 135 was dimmed (to a level that was comfortable to look at, I have no way of measuring output right now) and is 26” away. I know it’s early but I have no experience!

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

If humans took weed to grow on another planet where the sun was up for 28 hours and down for 10 hours, how well would it grow? Would the plants adapt to the different light / dark times? Or maybe 24 of hours light, 6 hours of dark? Theories? Earthly Proof? Comments? 👽

My grow tent is sitting in my basement, which normally sits at 10C in the winter, so I set the heat in the room to 18C and the LED and 2 fans heat it to 20.4C in the tent. Anyone have a similar setup but using their grow lights as a heat source? Heating a basement is expensive.
