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.

PAR/PPFD and light height
PAR/PPFD: does light height matter if your PPFD is in the right range? Another way to ask: is 300 PPFD @ 2 feet the same as 300 PPFD @ 20 feet, or are there other factors involved? (assuming heat, C02, all other non light inputs equal)

UV LED slowing down growth? Sorry previous question without the question!
The plant has a rectangular area in the middle where it is not growing as quickly. The difference is almost 10cm. I suspect the lamp. Could it be that the centrally installed UV LEDs are causing this? They should grow more inside because of more light.
