That's actually because of heat and the fact that LED's don't produce IR light, it has nothing to do with "intensity".

I see you saying this all over, but do you have any proof whatsoever? It seems like you spout off about stuff you don't fully understand all too often. I just got a quantum board two days ago and "intensity" is marginally superior to comparable COBs. I've done some basic PAR testing (far from...

No, do you know what a pH buffer is? A buffer stabilizes H+ concentration. Microbes in your soil (humates, bacteria, fungi) all contribute to the buffering effect it has. They live and adjust pH such that they can survive in their own environment. It just so happens to work out, these little...

It took me two years to deduce this. Great advice, always properly lime and let your soil stew for at least a month.

Are these gonna be less costly than a simple plate of aluminum, or is the selling point pre-drilled and tapped, and also lighter?

I didn't buy them all at once. I got 6 COBs at first, and I built my own engines, then I bought 2 of your engines. I just realized I'm also an idiot, because 4 of these guys are 4000k CXB3590's from a previous light. I can't remember exactly, but it's been a month or two putting this setup...

I got my light engines from you, actually. They're all 3500k 80 CRI. I'm just running your standard heatsinks with the active cooling fans. I'd love to do away with active cooling.

I'm a peaceful guy just trying to grow some jazz cabbage for me and my friends.

@CobKits My dude! Keep us updated on that stuff. Do you think you can test vs. your 1825 light engines at various wattages? I'm running 16 of those guys at 80 watts each over my 8 x 8 and these quantums are looking mighty appealing for my new 4x4 that I'm putting up.

@robincnn What would you recommend for a 3x3 tent in flower? I'm doing a new pheno run in there in about 35 days and the light I'm running currently is pretty damn shabby. I'd love to upgrade to something like this. I was thinking 6 of these boards run somewhere in the 50-75 watt range with a...

No, the galaxy hydro lights are snake oil. Stay away, they put out just as much heat as an equivalent wattage HPS and they're often less efficient. Avoid everything but high end diodes or decent COBs if you're going LED. I would recommend with your budget you simply get the 600 watt HPS for your...

Yeah I agree with this. That being said, bokashi is really just fermentation prior to composting. It's a rip off if you're paying for the brand name bokashi grains and stuff, you can accomplish the same thing in a five gallon bucket with some of your own IMOs. Additionally, you're dealing with...

Thanks greasemonkey, that clears it up! Looks like my girlfriend's gonna be yelling at me tonight asking why there's compost in the meat freezer.

Hey Gene, I've been watching you and Gromau5's videos for two and a half years now and I just wanted to say you guys are great. You two are a big part of why I'm where I am today in the growing world. Maybe someday I'll be on that panel with you guys :) Additionally, I was wondering if you were...

I've found the KNF method for extract IMOs is just as good for creating a solution to speed up decomp, and far cheaper. Just extract some IMOs from an older tree's root ball using the KNF rice box method, make the IMO mollasses mixture that's commonly recommended everywhere, dilute that 1:100...

I've done a similar thing for a long time, sans "effective microbes". I throw my food scraps in a 5 gallon bucket with some already seriously bioactive compost, mix it all up, and let it sit for a couple weeks as I add more on top. It accomplishes exactly what bokashi does, it ferments the...

If I may ask, how did you manage to develop such bio-active soil? Are you going out and getting soil samples from different places (forest floor, back yards, compost heaps, etc) and making teas out of those/mixing them in with your soil? 50.1% sounds pretty high, but in fabric pots it's...

Nice little grow my dude! Nothing wrong with cheapo LEDs if that's what you can afford. I ran a mars 600 for a long time before I fell into the lighting nerd wormhole. What happened to the unlucky girl that passed away?

If you have bio-active compost (i.e. has good microbes and stuff in it) or you can get your hands on some fresh compost from a friend, you can easily bubble that with some molasses to feed (molasses feeds mostly bacteria, so if you're looking to re-establish beneficial fungus you may want to...

Thanks for the info Tupapa. Overwatering was one of my biggest theories for plant #2. Humidity isn't an issue at a constant 50-60 RH I think, but correct me if I'm wrong. Moisture should generally be fairly even, I water once every couple days for about 20-30% runoff which is then reabsorbed...
