Separate names with a comma.
Some folks don't want to mess with the light deprivation requirements of photoperiod plants and are willing to sacrifice some potency for the...
Hang them at the height where they register 2000 umol at center, measure the size of the light footprint where you get at least 1400 umol. Then...
We need some sort of non-profit dedicated to cannabis research. Something equivalent to what the Rodale Institute has been doing for organic ag...
They compared 22 different light systems in the study: 10 LED's, two double ended HPS, 5 single ended HPS, three ceramic metal halide, and two...
I have a friend who just started growing autoflower (you said you run 24/7, I assume you're growing auto). She uses it for sleep meds, just a few...
Could try to reach out to ag research department at U. of Utah and ask them about it. They might give you brand names, or at least give you...
No idea. Nor do I have any science to point you in the right direction on that one, other than get a PAR meter, make the rounds of your local...
Here's the video with dude showing you umol's with a meter. Check out how high the HPS are, much higher than the 3 ft recommended for optimum...
No light meter in this video. Last one they had a meter, and claim they are only getting 500-700 umol from double ended 1000 watt HPS. Appears...
Looks like I have a choice: believe a Youtube video, or believe a peer reviewed study by a state university ag department. I'm sticking with...
Still haven't seen anyone demonstrate the even, high umol coverage of a 1000 watt double ended with 1000 watts or less of LED over the same area....
1500 umol is what you need according to U. of Utah ag researchers, that's the most they can use, though up to 2000 won't burn a healthy plant....
Heat generated by lights saving on heat generated by other sources is real. Whether your space is heated or not, in temperate climates in winter...
Kilowatt hours per gram is a more accurate reflection of electric cost. KWH required for the grow, divided by grams of yield.
I'm dubious of the 2.6 micromole per joule claim from t-bone for his LED's. Is that from the manufacturer? Doesn't seem mathematically possible...
Yeah, dial down the red in veg. We agree, yes? It does keep the stretch down. Good to keep it on when popping seeds though, the red is what...
Economic Analysis of Greenhouse Lighting: Light Emitting Diodes vs. High Intensity Discharge Fixtures From the abstract of this study, done in...
Learning is fun. Best part of gardening, the next grow always benefits from what you learned last time, so it just keeps getting better as long...
I'll give it a read. Thanks!
Thanks for the info. What's you're technique? Soaking? Pureeing? Brewing with an airstone? How much flakes per gallon of water or soil?
