    Round 2! HLG Saber vs Amare SB800 RDWC

    Took awhile but I’m back to hydro. Got 8 cuts nicely rooted and they’re all pretty even. Same setup as before with the addition of 4 UVB bulbs. Last run I didn’t post exact weights because I feel I neglected HLG’s side a little more. But Amare won that round by about .5lbs and with the whole...

    Autopot/megacrop LED run

    Alright finally made the move from dwc to coco/autopots. AN 3 part nute line has been good but so many different bottles and the PRICE is whats turning me to megacrop and the extras. Dwc is great but it’s become too much work for me now. I’m also still a pretty crappy grower but am diving in to...

    Adding UVB spectrum to COBs - opinions on this setup?

    UVB Diodes

    Does anyone have any info on UVB in LEDs? I went to a cannabis show in Oakland recently and there was a new LED company there that said they had UVB in their lights. Just curious if anyone has used or tried UVB in their LEDs. Also, what is the difference between MCOB and COB? Sorry for...

    UV, IR, How much, for how long?

    I would like to add some "terpene enhancement" to my light bars. I just don't know what chips to get and how hard to run them. I'd rather not roast my ladies in an attempt at making them stronger. I'm sure some of you have learned the hard way. Any chance I can learn from your mistakes...

    UV supplemented lighting

    Seems they where all the rage a few years ago. Then they kind of fell to the way side. Now I see they're back as supplemented additions to LED, CMH and other fixtures.. Also a big advertising feature for MH, CMH, and HPS. Solistek even came out with the 10,000K "finisher". so what is the word...
