Most growers tend not to mix them. In theory there's no reason saying you can't. It may stress your plants though. If you have a look at lighting experiments on yt. You may find your answer.

Please help me understand LEDs as mains. Same amount of money I can run double the plants and produce larger sticky buds with hps/mhl combo. I was always under impression LEDS are a just a better florescent.

Should I dim my TS1000? Ts1000
When using two lights in a small space should I be worried about to much light? The plant is mature and is about to transition to flower, I’m just curious what is too much if any. The TS 1000 is dimmable the sf1000d is not. Lights are 18” at the moment

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?

Upgrade from 300w mars hydro TS to FC/FCE?
Will I get noticeably better quality results like denser heavier buds and more resin if I upgrade my light from mars hydro TS series to a bar light with higher red spectrum?

HLG 550 V2 RSpec power/height in flower
I’m using an HLG 550 V2 RSpec in a 3x3 tent over one Universal Kush plant. Anyone have experience growing with this light in a similar setup? What’s the best height from plant and intensity level should I set the light to? Don’t want to stress her, just want ideal light levels.

Bloom light on heat goes too high?
When turning on the bloom setting the temps seem to be getting up to 84 on the very top of my tent and around 80-82 by the bud sites. Is this too high? Is there any problem turning the bloom high power switch off to let it cool down for a half hour once or 2 a day if too hot?

Veg or Bloom mode for Autoflower?
Hiya Folks 😊 As I'm growing an autoflower should I be using the bloom setting on my LED light instead of veg setting? It's only a 200w system and I'm growing in a 3'x3'x6' tent. My plant has just done 28 days from seed!! Cheers 😉
