i run a qb600h. just used it for the first time and am impressed for sure. it's over a 4x4 area so i dial it down to ~510-550w or so at the most. i just finished flowering a cookies n chem female which you can find pictures of by going through my post history.I hate to change the subject and possibly end an exhausted argument, but is there anyone growing out any GPS with HLG QB’s?
Curious how they grow/stretch under those LED’s.
it's 3000k so the plants weren't super compact, but they weren't lanky by any means. was my first time growing the cookies n chem so i don't have a comparison on that one, but the rainbow jones cuts i had in there with it i have grown a few times before and they stretched a bit less than under hps, but not by a lot.
pros:
- efficiency
- great PAR
- versatile (potentiometer)
- lower power (than hid)
- lower heat as a result
cons:
- requires a lot of headroom to really crank up (had foxtailing from a plant at ~20 inches)
- requires a lot of headroom to achieve proper coverage (this light is literally the reason i bought a gorilla tent. needed as much height as i could fit in the room which is 9 ft with about 10 inches to the ceiling after that)
- expensive(i had mine assembled and tested and also had a potentiometer added. was ~$800USD after shipping to canada)
- not really a 'con' but it's quite heavy
