Good luck, it could be very informative if done right What medium? Clones?

I used these bulbs (or the rebranded equivalent), IME they seem more prone to failure than Philips bulbs over time. I haven't had a philips bulb burn out and become unusable. I'm sure it happens, but with these it happened twice to me. maybe it was just bad luck. One of them burnt out after only...

Well, the bulbs they sell are available on alibaba I'm sure the rest is too ;)

Indeed, in that case I stand corrected

Are those CXB really >190 lm/w at that current? hard to believe from an 'old' cob. Maybe I am mistaken. If you decide to use a strip / midpower led build I think you can gain about 20% light for the same power. That's my experience going from cobs to strips. That said I agree with @OLD MOTHER...

To me the hydrofarm meters look like overpriced lux meters. Big white circle, available for $15-20. Does hydrofarm use different technology or is it just a lux meter with a conversion rate?

I find that I consistently get the best results from clones that are left in normal humidity conditions. Only the stem needs high humidity. I think the clone can get water more easily if you peel off the outer green layer off the bottom of the cutting, but I'm not sure Some plants get unhealthy...

Very interesting. I'd be interested to see the difference between a normal 12/12 from seed and this lighting regimen. 28 days?! edit: ok I get it, that's critical mass X big bud lol.

You should be able to take it way farther than 13/11. That has been my schedule forever. Doesn't need FR

2 rules of LED: Everybody loves to talk about spectrum and nobody wants to do a side-by-side. Well, except researchers at Utah state university, whose work so far is showing that there is no difference in yield between plants grown under 4% or 20% blue. I would just go with 2700K. it's a full...

Yeah I was shocked when I saw that. I dont know the guy but he wrote a lot of interesting stuff, definitely worth checkin out via a web search on his name. Cheers

There is this guy on reddit who seems to be a master of short internodes. He puts blue light on the stem and calls it selective light training. Google for "SuperAngryGuy" all credit to him. I don't like reddit, but it seems that he only hangs out there Pea plant: Jack herer: Mystery skunk...

Gotta love the anger of noobs Keep rinsing and using armchair bro science, I'll keep testing (Noob mentality, not noob at growing)

Dude put the cover on your filter you are reducing its lifespan.

Yea another +1 for this. Just test what you buy and dont waste your time "rinsing" lol... "Just bought a 50L bag of premium coco, now before I use it let me run 400L of water through it" Hahaha.. lord listen guys if you have such little trust in your medium there are plenty of options that are...

Between those 2, the mars

Well, you have to differentiate yourself somehow, but even if the lowered B:R ratio made no difference the reds would increase efficacy. What's better, who knows. This is better, that is better. WHatever. you could probably grow it hydroponically in tomato soup and still win the high times cup...

Scientists are scrambling for explanations after the theoretical maximum drama per joule has been achieved by a hitherto unknown party

Mate the DIY led rabbit hole goes so deep that the rabbits just fall into the earth's core and burn up. I understand you are getting a migraine. Maybe its best to start with something simple. Sellers like HLG didn't get their reputation with red diodes, they got it by making good lights that...

Well, earlier on it truly seemed like you were on the HGL payroll with some things you were writing. I'm sure this plot twist has surprised many. Of course the honesty is appreciated. I look forward to reading Cameron's delusional excuses when I need a laugh.
