As some of you know, I've been trying to do a decent grow with LEDs. So far I'm not impressed. The last time I tried, it was with a small plant in a 16 oz cup growing in soil and using 13 Watts worth of LEDs. The yield was about 2 grams. More info at this thread: http://www.marijuanapassion.com/forum/showthread.php?t=10461 Well, I'm at it again. This time, I'm using a 2 liter soda bottle with the top cut off. The medium is 50/50 perlite/vermiculite and I will be hand-watering with Hydro nutes. There will be 9 LED arrays this time for a total of 30 Watts. The manufacturer states that each array uses 5 watts, but when I measured the power draw, it came out to just over 3 watts per array (or bulb if you prefer). Last time, I started from seed, but this time I am using a clone. In fact, I am using a clone from the regenerated plant I used last time. I left a couple of buds on it and re-vegged to get some clones. It was so frosty that I didn't want to lose it. As a control, I will also be growing another clone using the same method and the only difference is that it will be under my 400 Watt HPS. Now, before anyone gets on my case, I already know that the HPS grow will blow the LEDs away. I just want to see by how much. Up to this point, I vegged the plants under a couple of 2 foot fluorescent tubes for about 3 or 4 weeks (I lost count) and started flowering under their respective lights about 12 days ago. The strain is White Satin from Mandala. I'll try to keep this thread updated every week or two. Comments, suggestions, and questions are welcome. Just be polite. The Pictures: 1) The two plants side by side taken last week. The one on the left is being grown under the HPS and the one on the right is under the LEDs. Notice that the HPS plant is already a little bigger than the LED one. 2) Close up of the HPS plant. 3) Close up of the LED plant. 4) The LED lights. Sorry about the blurry pic, the camera had a hard time focusing. 5) The LED plant in its box.
