I am looking to set up another set of quantum boards. I’m trying to keep it under 200$. So I guess I’m wondering is it possible to hook four (4) of the 288qb to a LRS-350-36 ??? Or should I just get a 4 pack of the qb132v2 ? Any ideas would be appreciated. I’m trying to figure out a way to get...

I was doing some measurements for a second 4x4x8 tent in my basement to house a QB to finish flowering in. Ive currently got one whole room dedicated to vegging plants with two 4x48" t8s (6500k), as well as a 4x4x8 tent with an aircooled 600 watt HPS. I wanted to use the leds to give the plants...

Good day growers! A while back I purchased a QB-70 4000k specifically to reduce electrical costs, so far great results after a period of 2 months vegetative.However upon looking around on the site for another QB to replace my 600HPS, I came across a review: "450g from 320w of COBs is just...

I think a lot of people want these. Has anyone have the info as to when they will be available ? Has anyone settled for something different? If so...what? Is the difference between 3000k and 4000k that big ? Gratefully growing 3000

I just got two of the new RSpec HLG 260s delivered and I'm replacing my single HID thouie. I've always loved my Gualala Robotics 3.5 mover. It left the factory in 2004 and has gone though a few rebuild kits. I also have an extra trolley. I'd like to mount the LEDs side by side on the light mover...

Looking for most affordable yet efficient led cob strips. Any ideas ? Thank you I Wana build something out of the cob strips but looking for a decent price on them. I figure people on here would know about strips that came out two years ago or a year ago that are still really good to use even...

Hi all I’m looking into purchasing some cob led strips. What is a good spectrum to buy for veg/flower together ? I think I heard 3500k but I’m not sure. Also what are some affordable options for these strips ? Besides cutter led... thank you for your time

Hey guys, so decided to try the Kingbrite equivalent of the HLG 320W XL QB V2 R SPEC LED KIT. Figured I would give it a shot and have something to report back to the group on. Only question I have left is the option of installing the driver in a different location. On all these kits it looks...

Looking to get my first set of quantum boards, actually first LEDs for a longtime traditional HPS grower. Gonna go Chinese (kingbrite) for budget purposes and trying to decide between these 2 boards. Both are 3000K, : QB288 LM301B with Epistar 660nm - So 36 of the 288 (12.5%) LEDs on each...

What Happened? I bought 2×800 FOTOP V1 full kits from Meijiu and received them in July 2018. In March 2019, I purchased 1×800 FOTOP V2 kit and 2×25W Supplement Red Bars Important to note that I drive my boards at only around 50% of max power. With heatsinks no less. So they should last longer...

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...

Hi everyone and thank you for your time! Looking for some help on how to limit flowering stretch with quantum boards. Using (4) QB132v2 3500kspectrum in a 2.5ft by2.5 ft tent that’s is just a tad over 5ft in height. I have done a lot of LST from the beginning bending and tieing down branches...
