If your in the US and still need seeds send a private message and I'll send you some I got a few extras

Usa, thanks for another great opportunity @Spiderfarmerled @Tracker

I'm hoping in the near future uvb diodes will be more readily available and cheaper, the price is outrageous. The only way to figure these things out is thru testing, and unfortunately this market has been tainted with companies selling a dream and only showing test results that benefits what...

I have noticed an increase in trichomes with the pure uv tubes they are 75% uvb 25% uva but there is no way I could run them constantly unless I was up like 4 foot and slowly broke it in, I guess that's my biggest issue with them, I've seen so much controversy over the whole uva vs uvb maybe it...

I've been using the agromax t5 it'll roast a plant fast lol I've been looking at those solacure tubes I will need some soon I'm on my last bulb

Lol I was stoned looking up diodes and data sheets I didn't even realize those were In Germany I gotta find a good American distributor I've had real good luck finding cool led shit at flashlight stores online.

They're. Actually 3.7 volt at 1400 ma so technically they are just over 5 watt max but typical is 1 amp running at 3.7 volts so let's say I'll run these at 3 watts each. What your reading is the spectral output which is how color leds are measured Instead of lumens.

I've been using t5 for uv lightly throughout flower and a Lil heavier towards the end, I want to build a led fixture to replace this. From what I've researched, nichia is the best option for uv, I've been looking at a few other options as well but here's what I'm looking at purchasing it'll...

I don't think you could possibly hurt the plants with that light. I'd try to get closer to the 12" %100 range I've seen em almost touch and still be fine at that low of power, the par maps are exaggerated and under perfect conditions, 20" away to far

Wish they would sell these lol

I would like to get the Gerber file for the qb96 and have a newer one built, as far as the 5050 diodes go without an electricaly isolated thermal pad nichia has the best thermal conductivity, I would like to try those diodes and a copper plate instead of aluminum to increase thermal...

The first one I ever bought same thing lol.

I've been using the new cmu2287 cree cobs, 82 watt typical 240 watt max decent efficiency. I've not given up on cobs like most

I've also made my own heatsink at work on a lathe, I work in a cnc machine shop. Super simple I used like 2 1/2" aluminum round and put a million grooves in it I used to have ebay cob mounted to it, I should write a program to do this to like 4 foot long bars then cut them in half so I can mount...

I hit the aluminum jackpot at a yard sale he gave me everything he had along with a couple hundred feet of copper tubing, for smoke ive been slapping sunboards to 1.5" x 1/8" aluminum angle iron. I been thinking about how hard it would be to melt some down and make some heatsink molds

Citridelic sunset ethos

I have one that was completely odorless I swear it's a frosty mofucker too? After some cure the citrus smells are coming thru though. Lemme find my camera this shit looks amazing

Have yall done any testing swith those cree jb2835 g class 3.13 ppf and 1.5w max are attractive #s wish I had access to some of that testing equipment. Nichia is awesome they're responsible for major advancements in the past, led wouldn't be what it is today without them.

I have to use flourecents for uv and diy for ir, or nir all that adds up definitely

With the new advancements in high power whites at cree and nichia that efficiency gap between high and mid power is closing, regardless do you remember the old qb96 boards (I shouldnt mention other company's in your post, apologies. ) anyways just for reference, they weren't the most efficient...
