They really don't need to be placed a lot higher than most powerful recent LEDs, just depends on ventilation/circulation and room temperature. But in that size tent, I would expect you had trouble maintaining a proper temperature. As for height above canopy, 2 feet is a good average, some people go much lower, some go up to 30" or so with them. If your plants were budding at 18/6 it is most likely genetics, not related to the light. What strain/breeder? Lots of auto genes floating around nowadays.I have a 2'x3' footprint and just over 5' tall tent with a 315w cmh lec with ballast in fixture (Sun Systems Flower Power). I was vegging some plants indoors last february as high as the fixture would go and they started budding at 18/6. I've read things about needing to place these much higher than LEDs, would the stress of being too low have caused this and how high should I be keeping these?
I tried using the search function and people have mentioned height but I didn't find anything specific, sorry if I missed it.
I highly doubt these were autos. I was also using a hygrometer to keep track of the temps. I forget since it was so long ago, but it wasn't above 90F. That said, there was no exhaust ventilation, only a clip mounted to the side poles.They really don't need to be placed a lot higher than most powerful recent LEDs, just depends on ventilation/circulation and room temperature.

@F1_Grower is that a John Wayne Gacy painting?Thank you!
I think I've done it, reached my sweet spot!
As a Systems Analyst I couldn't accept failure with my first harvest under just the two huds doing open loop and wanted to automate as much as possible/create ideal environment. Ran ICC and katsu kush first time indoors

Thanks to all RIU members for sharing in your wisdom, knowledge, and experience
Job well done sir......question, how are you drying@F1_Grower is that a John Wayne Gacy painting?
How are you getting a even spread in a 2 x 4 space with a 315. I ran one but ran it with two small 100 watt led boards and still didn't have great coverage throughout. That was in a 4 x 4 however. Plants look great!I just switched this fun from the Chilled led 300w set up to the 315 vivosun cmh and i am loving the results. I am running 4 plants in a 2x4 area of my shed, and it's about 14 inches from the tops. Just did it for fun to mix things up. Weight is definitely up substantially but frost is done at least 20% - from what my eyes can see. Not bad for a $149 light

Thank you! Honestly is not an even spread, the last two plants have to be rotated in the middle every other day. Kinda a pain in the ass lol but its working. But it seems to be working well. I might add a 65watt HLG quantum board this week to add a bit more light on the edges but we will seeHow are you getting a even spread in a 2 x 4 space with a 315.
