What do they mean by micro (random) on those tests?

So calnit is ok to use with regular soil mix? I've been looking into international ag labs high brix growing. I think their philosophy can really be tailored to any style of growing the key thing is they break the type of nutrients down into "growth"and "reproductive" periods. Nitrate, calcium...

Does anyone know if any of Jacks soil ferts are high in nitrate nitrogen? The ones I've seen are all mainly ammonia and urea nitrogen

I thought it was incredibly interesting. Thanks for posting. I particularly liked the part about different types of nitrogen impacting growth vs reproductive energy

I think likely we'll see them be distributed more to major big box outlets and the price come down substantially. Gavitas for ~$250 at home depot...that sorta thing. Generally when a small niche company gets taken over by a bigger broader company the quality doesn't improve but the distribution...

Nice setup! Do you notice better results with the plants under the 630? This guy over on IC did some tests on the phantom and cycloptics CMH hoods and they look pretty impressive in a 3 x 3 for 315 watts: https://www.icmag.com/ic/showthread.php?t=327419 Also are you using the gavita 600/750...

I can see advantages of both. For growing bigger plants if you can get an even distribution over your area with a point source light from 3 feet away it might be worth the 200 extra watts due to better penetration. However, I think even distribution in most cases is severely under-rated. Ive...

Curious if any of you'll have used the gavita small room reflector? It's supposedly a lot better for even PPFD in small areas. Their regular reflector is made for hanging at high heights in big rooms with lots of overlap with other lights. Here are a couple of profiles they have for their small...

I have that same unit. It seems to do the job well enough

After looking at that chart I'm a bit confused. Isn't total Umol is the same as PPF? So PPF/total watts = efficiency? Based on that I'm getting 2.34 umol/watt for that CXB setup.

Oh wow you're right I do stand corrected. That is an awesome light! I had no idea the Cobs efficiency had gone up that much already. I was mainly using info off this post by greengenes from last year: Gavita double ended... Still gavita is pretty darn efficient compared to most lights.

I think there's a bit of misconception between gavitas and heat. Yes they do run hot but they run hot because they're putting out a TON of light, not because they're creating a ton of wasted heat. A gavita DE puts out 1.82 umols per watt that's amazing efficiency. It's about double the...

I dont see how making things more legal is more government intervention than keeping things illegal. What I've been referring to isn't big Ag at all but small ag. All those oregon licenses going in are all considered small mom and pop operations because they're restricted to no more than an acre...

I'm not talking about any government intervention. I dont really know too much about the gaffe between medical and recreational in california - have heard a little but haven't looked into it much. All I'm saying is if the dispensaries you sell to have 100 other Saras and 100 other Billys...

Taxes will help keep prices higher but not sure how long those super high taxes will last as things become fully legal federally. Marijuana is a potentially big industry the main problem is it's really not THAT big as far as how much growing it takes to meet demand and once you have a market in...

It will take some time. Legal production is still in it's early infancy and both those states put severe limitations on production licenses. Oregon will be a better representation of what cannabis will look like in a full legal environment because they have more of a free market policy for...

Ag doesn't just mean pure outdoor. Greenhouses with supplemental lighting are already used for every crop imaginable, their technology is rapidly improving, and it takes a lot less supplemental light one might initially think to grow in most places...

I've done quite a bit of research into the tomato model and figure the ultimate wholesale price of cannabis could fall as low as the ~$50/lb area. Tomatoes sell for ~$1/lb wholesale, and their are farmers making money at that price. Tomato plants grown in greenhouse or outdoor produce ~20-30...

How did they turn out?

Great thread here. Curious if anyone has built 4 CLUO58-1825 in series? What kinda holders/heatsinks would be compatible with that, running at 1050?
