That’s a great idea. You can always move it out once they level up a bit. I’ve had the same issues but I’m doing 5 gallon buckets DWC and I was able to prop them up.
I leveled up my lights and with 2 @ 480w HYPHOTONFLUX HLG4000’s, 4 80w far red LEDs and 1 100w UVA led. I took clones from two mothers and blew up my tent with GSC extreme clones. Keeps the canopy somewhat level.
