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.

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 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.

This has been my first experience growing with CMH after 5 or so years of using HPS. I have to say that at first, I was dissappointed because light coverage isn't as strong. And sometimes throughout the journey I was doubting if it was even comparable to a 400W HPS. I even made a thread.
Well, let me tell you I was wrong. I stopped looking at my plants and just watered them with some nutes when if I saw my soil dry. But I didn't look at the buds. I do this because if you stop looking at them after a few days/weeks you can get some nice surprises. And I did.
21 days without looking at them, but when I did, I saw the frostiest, best looking buds I have ever seen. These plants have only been vegged for barely 3 weeks, and some buds like the mazar i shariff strain (pic 2 and 3) are the size of my fist and literally glowing and sparkling everywhere. Pictures don't do it justice especially with my crappy old iphone, but you get the idea. The first pic from reina madre strain is totally covered in resin. It's the frostiest plant I have ever grown.
The smell, terpenes, resin production (can't speak about taste yet) is much better than my Phillips HPS.
Overall I am pleasantly surprised by the 315W CMH. I am not going to say it produces bud like a 600W HPS, but in my case it beats the 400W HPS pretty badly. I'd say it is somewhere in the middle, equivalent to about 500-550W. I have never gotten such compact, good quality buds with such little vegging time. Excited for what the future holds.
Now I am going to grow some lebanese hash plants and I can't wait to produce some top quality hash with my CMH. Could not be happier. Just wanted to share my experience.
Cheers.

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

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!

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 see
