    Theory on LEDs - Why they need CFLs to perform

    Here is Mazar-i-Sharif 35 days into flowering under LEDs and CFLs. I'm hoping they dense up a bit more, but after 35 days I'm pretty happy so far.

    Theory on LEDs - Why they need CFLs to perform

    ...Continued So what happens when CFLs and LEDs are used together? The spread of light from the CFLs make the plant bush more, creating more surface area to absorb light. Then, the intensity and spectrum specific light from the LED promotes extremely healthy and fairly rapid growth. Can...

    Theory on LEDs - Why they need CFLs to perform

    So, I've been really thinking about this whole LED thing lately. Why are so many people having such different results? Why do the CFL + LED grows do better than the 100% LED grows? My first thought was that the CFLs must be doing all the work, since I had seen so many bad grows that used only...

    496w LED/CFL mix grow

    Thanks for the link! I wish he was a little more organized, doesn't really list his total watts or yield. But, there are some nice looking buds there. I keep reading scare stories about LEDs, but my plants are looking great and still have over a month left, so I can't make my estimates on how...

    496w LED/CFL mix grow

    Here is a side cola of the Mazar-i Sharif close up. It's hard to get a shot to focus with my camera, so I took this from far away and cropped it. The resin is beginning to form on the leaves close to the top of the cola, hopefully these nugs will start densing up a little.

    496w LED/CFL mix grow

    I was thinking of going aeroponics or ebb and flow for my next grow. I've always wanted to try HPS with LED too. If I can get better ventilation I might try something similar.

    496w LED/CFL mix grow

    I actually used 2 different companies. This is part of the reason it took so long to get them, I didn't buy the first LED i saw. Here are the two companies I used. The price has actually gone up slightly since I bought mine. http://www.hydroponicshut.com/...

    I've looked into a lot of these options. I am very curious about the UVB, infra-red, and other spectrum of blue. One product that I've heard has incorporated all of those is the...

    496w LED/CFL mix grow

    Here are the pics. There are 4 plants, 2xMazari Sharif, 1 bubble gum, and 1 purple kush. All of them were vegged from clones outdoors until I got my setup. It took a little longer than expected, so they got a little big. The Mazari started flowering a week early outdoors, so they are a little...

I got about 14g of dry bud from that tiny grow. No nutrients, just water and some worm castings. Usually I would say...
