@DeepWaterGrower,these are TLEDs for flower from Secret jardin, actually just borrowed them of a friend, thatβs why they are so long, each has 42 watts (95cm), but you can get them in 54cm and then they would have 26 watts.
From what I read plants can do photosynthesis also with the lower side of the leave, therefore that should already be a plus and I have realized that it helps with the swelling and ripening of the lower canopy, meaning the budsites on the top and lower canopy get closer from a trichomes a appearance perspective. Be mindful of the heat though, as you are introducing a heat source under your canopy, so you might want additional ventilation under the canopy
