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.

Lower lighting at switch to 12/12?
Do you typically want to lower your lighting when you switch to 12/12? I'm a little confused about what is meant when they say to have a 12" light distance for flowering and 18" for veg. Does that mean lower to 12" at the switch to 12/12, or just maintain a min 12" distance?

Too close to the βsunβ(light).... any advice?
My plant grew close to 4x itβs original size during her stretch, 10-12β on day one of 12/12 to 46β tall. Sheβs on day 30 of flower and I set up a second ScrOG net. Other than blocking light to shorter plants, do you see any other potential problems this second net might cause?

TRUE OR FALSE!?!?
True or false?!?! LED has a longer flowering time. LED needs less nutrient. LED has a more spread light output. After reading to much about it, I would like to know what GD community thinks. πππππ

Do you lower light intensity and temps towards the end of flower?
So Iβm in mid flower, start of week 7 to be exact. Iβm curious on when you guys start pulling back light intensity and going with a little cooler temps. Iβm running a 240W S33 from AC infinity in a 3x3. Should I be going strictly off of PAR or VPD at this point.

LED light distance
Hey guys I'm kind of new to growing only been doing it for a little over a year. My girls grow really well they just don't get very tall I'm thinking it's because my lights are too close. Is this correct? Distance is 9 inches above canopy in week 6 growing critical 2.0 autos.

Is it worth adding a LED 18w 2700k strip light for last few weeks of flower?
Should I add this light for the last few weeks of flower? I have a Streetlight 18w LED strip see pics. I was thinking that if I added this strip designed for flower to my tent like a side light it may help my Viparspectra V300 in fattening those buds a little. Thoughts?
