Temperature (regardless of what light you grow with) affects your overall yield and growth rate. CO2 further increases the rate of photosynthesis and the difference in growth achieved at various temperatures. The higher temperature you run for a plant (to a certain point), the faster it will...

Hybrid and I have had a private discussion on this matter over the past few days. He has agreed to take new clones and start a new thread where all the variables listed by concerned members have been corrected. I applaud him for this and also for extending an olive branch to me privately. It...

Cooling passively and cooling efficiently are two completely different things. I can also make our LED lights passive cooled (in fact with X-PRO this is an option we offer); however the heat sink temp rises to 135F (57C) on X3 which causes a spectrum shift and output loss from all LEDs. The...

Sweet deal! Nice little addition for the time being considering there is so much lit area that isn't growing anything :) Our LEDs are run at 600mA last I checked. We ran them at 550mA for years and did bump the amperage to 600mA, but this had nothing to do with lens loss (as we've been...

And thus far what are your conclusions?

I wouldn't have an attitude if the guidelines had been followed and you weren't putting up so much opposition to following them (until now). I don't like having an attitude or being put in the position to make ultimatums for guidelines to be followed. You and I started off here very friendly...

I'll be sending out return labels for those lights. We will find another grower who will run this test who will show gratitude and respect for the opportunity they have been given. I'm not here to be liked, I'm here to prove my products perform better than any out there.

Any excuses seem to be rubbish but your own. I guess your opinion seems to be the only one that matters. Hmm, can't clone? You cut a stem at a 45 degree angle, dip it in rooting get and put it in a rapid rooter... which is then placed under a light. This is pretty simple stuff man, so don't...

It would be painfully obvious. There is only one position the lenses can be placed in where they are aligned with the LEDs. If the lens is misaligned it would be angled about 60 degrees offset from where it should be. The way the lights are engineered and assembled, you don’t need to worry...

If you take clones from the current plants you’ve been vegging, and then move those plants to your other spaces with all you’re other free lights (interesting how you talk about cost when almost all your equipment is free) how exactly are you losing money? And how does starting new clones...

Awesome! Thank you. I'll read up on it tomorrow. Might need to make a specialized light just for lettuce for the next round.

Do you happen to have any links for said studies? I'd love to see any research on spectral development for lettuce.

You use a night cycle on lettuce? What are you hours on vs hours off?

All of our side-by-side grow chamber testing done at the University of Washington on lettuce, was performed at a fluence rate of 300-400 umol at the canopy level. According to the professor, this was the ideal intensity for growing lettuce which is why I requested our light be used at 16.5"...

Best thing about a lettuce grow? It happens so fast! Plus who doesn't love an awesome salad? Glad to see we passed test #1.

I'm only responding because you (the OP) addressed me. I'd rather sit as a silent bystander for the majority of this test and let you (and our lights) have the spotlight. What's there to research when competitors are using white light? It doesn't matter if it's MH, CFL, LED, etc... white...

You're very welcome, although I recall things a little differently. We offered the opportunity to test our lights against whatever HLG light you wanted to choose from your own arsenal (as you have more than one). Then when Stephen found out he decided he would send you a new light, rather than...

A special thanks to @OneHitDone who is taking the time and making the space to run this grow test. I have no doubts you'll be happy with this little light for your lettuce crops. Your popularity around here (especially with lettuce) is what won you a grow light. That and I think you're a...

Stephen your reputation here is already weakening. People have already called you out on my threads... And once the grow tests are finished, you'll have very few left here who will support you or your lack of responsiveness, question dodging and complete lack of a fundamental understanding of...

Once again real information is posted by a third party this forum asked me to contact for testing, and rather than discussing the content of that company's information all anyone here is doing is trolling me and trying to change the subject because they don't want to admit I know what I'm...
