You might be. Ive seen 3-4 grows on hear that looked to compete easily with HPS. Quality of bud was to the T, and yield was also great. About a 3x3 area is what i saw, and i think theirs someone with a lamp that covers 4x4. It would be real interesting to see how the 4x4 lamp does. Totally impressed by what their all doing.
You are pretty much referring to what is called vapor pressure deficit. Its not as easy as high temps low humidty because yes, plants are sensitive to humidity, very sensitive. High temps with low humidity will likely lead to plants wilting, they can only transpire at a certain rate, you have to get as close to that rate as you can with temps/humidity. High temps, relatively high humidity. Low temps, relatively low humdity.
VPD explains why I run in the low to mid 80s for temps and seventies for RH.
I'm about to build a monster COB LED array that will prove once and for all whether LED can scale up to larger grows- or if it's still a toy for postage stamp ops.
There are plenty of folks who arent impressed but if they observed the grows done with top gear the only explanation could be denial.
I think the ability to think critically is independent of one's predilection for puffing pot pipes. I know lots of people who are good at thinking critically and nothing changes when they get high.
Good luck to you. I'd like to see this grow.
ok good points...but you must admit your not going to defend your PhD dissertation stoned or logically entertain seriously complex issues stoned. Im familiar with smoking and also with cogent thinking. Stonedness certainly does not lend itself to rigorous disciplined thought.
This is exactly the assumption I aim to put to the test. I'm not saying you're wrong, I'm saying my hypothesis is that this is incorrect and I'm going to build a test rig to prove it one way or another.
Just make sure you buy Cree products please.....
Rigorous, disciplined thought is just that- a discipline, requiring practice to achieve and maintain.
Cool. Maybe I am in denial lol. You know, maybe I will try a small led setup, for myself just to say I did it. If I ever get around to it. Not an experiment like what your doing which is more interesting. What I'd really like to do is have the terp profile analyzed compared to hps.
CXB3590, @56% efficiency, 3500k color temp. Oh yeah, the parts list is coming together!
i use that exact combo 72v
it doesnt seem like youve done much research. Shitty leds will produce decent weed and decent weight excellent leds will outperform all other technologies.
Greengenes did a side by side, LED vs enhanced HPS using the blue dream clone-only. The LED bud tested higher in cannabinoids and terpenes and yielded higher in gpw. Something I have been coming to realize, even when my ambient temp is under control, actual bud temp also depends on light intensity. That is why many people prefer the mid level nugs rather than the uppermost in the canopy. Most varieties bud's really do not like high temps, CO2 or not. So even with high efficiency COBs and low canopy temps, I have to keep an eye on bud temp.
Thanks, interesting article. Would have been nice if they gave the variation in THC content for different PPFD levels too. Still, it does show that growth increases right up to 2000 PPFD, which is sunlight at noon in summer.
