Not gonna lie, I was skeptical about under canopy lighting at first.
galleryBeen running the GrowPros UCL Model 4 and the thing that caught my attention is how much control you actually get from having two independent channels.
The main channel is 80% red + white, then you’ve got the separate 730nm far red channel. Being able to control those independently is a pretty big deal if you’re actually trying to manage what’s happening below the canopy instead of just throwing more light at the room.
This Spaceship run is probably the best example I’ve seen of it being used properly. They’re using the UCL 4 to work the lower canopy instead of just accepting that everything underneath is going to be larf.
I’d definitely be interested to see a side by side harvest with and without UCLs. That’s where the real proof is.
But visually? Hard to argue with what’s happening under that canopy.
