Yuuup I’m late to the punch on this one lol. Thanks for the tag @cobshopgrow.
@andreav-
I just built an all purpose light using 15 bridgelux eb2 280mm strips. 3500k since I’m vegging and flowering with them. I can’t say that I have any experience vegging with leds in a 5000k spectrum though...
Id keep an eye on the sugar leaves at 6 hrs on time. The fact that you’ve spaced them apart should be sufficient but I just did a run with 6 hrs consecutive and definitely had drop in THC and sugar leaf burns. Im also running the zoomed 10.0 on the 4 ft ballasts. I’m planning on keeping it light...
Exactly, it’s a fine line to balance on of too much UV and not enough. Basically like a tanning booth, too little radiation, no effect. Too much and the plants end up like that chick on final destination
Yeah that’s a good call, that type of structuring was prevalent throughout all phenos, upper colas had a bit more of it.
I started at 2 hours a day at 18” and ramped up to 8 hours by week 8 but dropped it down to 6 for weeks 8 & 9. This coming run im going to start at 30 mins and work up to 4...
First and last time running it so I couldn’t say for sure, but the buds do look very similar to the breeder pics so I’d say the strain naturally has some fox tailing occur during flower.
I just finished up a run with the 10.0 reptisuns. Two 48” zoomed ballasts configured into my board set up. Worked great at 18” above canopy but almost too great, got quite a few brunt tips on the sugar leaves that made trimming a cunt. Frost galore though.
I ran it from week 3 to the end of...
Thanks for the mention @Rocket Soul ! I haven’t been in here much but I added in the UV T5 and so far it’s been great. Buds are very frosty. This run has been sensitive to feed, anything over 500ppm on my meter and they all get angry.
It’s definitely not a featherweight unit but I’d say probably about 35-40lb. I have it supported with 4 3/16 rope ratchets, one on each corner. No issues so far. 3rd with it and some more very happy plants.
If your light is non dimmable and is outputting 135w all the time then yeah, 18 would be too close. Seedlings can also stretch and get lanky due to heat stress like lettuce does, which you may have been experiencing with the light so close. Go to 3 feet and if you still get stretching bring it...
I would definitely raise that up. I would probably say 3 feet if you’re unable to dim the 135. I have a 4x2 for my veg space in which I use three QB288 boards on an HLG240. Currently it’s at 130w and I have it 3ft or so above the seedlings, just to give you some perspective.
I’m not sure if it’s dimmable. If it’s not then you’ll have to play with the hanging height to adjust your light output levels. How big is the veg space?
