So, in these large 20+ gallon sips made of totes, do you ever clean the reservoir? I mixed up some super soil, it’s been cooking for two weeks. I’d like to try no till, sub irrigated, but I’m not sure if I should use large fabric pots sitting on trays of perlite, or build a tote sip. I worry...

Very helpful, thanks. Will you use the far red and uva full time, or…

Beautiful! Nice work! I’d love to know more about the components you used for the far red, uva, and their driver. Is that already posted somewhere?

Hi. I’m hoping to get some advice on a flowering light for a 3x4x7 tent. I planted a few seeds about a month ago. I have them in a 2x2 cabinet with a single qb288v2 4000k (my first LED’s!), the plants love it. I have a 3x4x7 tent (35”x51”x81” actually) that I’ll be flowering in. I’ll be...

Thanks. I’ve started LST with this vigorous gal. She’s very responsive. It’s been fun.

Any updates on these strips?

Update?

Has anyone fired up any of these strips yet? https://atreumlighting.com/collections/frontpage/products/ara-20-led-light-bar

i have a triple cheese (Barney’s) feminized. She’s working on her third set of leaves now. I’m not sure if I should LST her, or mainline, or what. She’ll flower in a 2x4x7 or 3x4x7 tent. Any advice?

Aw, c’mon! Have a nice long safety break and then fire up that bandsaw! Pics please.

I hope so. Maybe with some reds? I hadn’t heard of the gmo show. I’ll check it out.

hlg restocked their 288v2 this week after being sold out for a week or two. They also dropped the prices a few bucks. I’ll need a new light in a month. I wonder if I should get some qbs while I can, or if the price drop means that v3 or something else amazing is just about to be released?

I used 14ga copper wire. It fit the wagos and the board just fine. I think they accept up to 12ga

The qb324v2 in 3500k looks pretty awesome. https://horticulturelightinggroup.com/collections/quantum-boards/products/qb324-with-slate-2-single-combo No soldering required, just a couple of connections using wagos. You can find plenty of help matching drivers etc , both here and at ledgardener.com

I just wasn’t seeing it, until I was

Hmm. Testing…

Ok. Thanks

I just got my first qb. It’s a 288v2 4000k. I just have seedlings under it currently, they love it. I chose 4000k because when you compare the charts side by side with the 3000k, there is very little loss of red and a substantial increase in blue. To me, it just seems like extra light without...

Uhh, I don’t think so…
