504W Independent Test with LED Grow Lights - LED Grow Lights - International Cannagraphic Magazine Forums

My friend (who wishes to remain anonymous) allowed me to photograph her grow using 4, 126W Penetrator LED Grow Lights from yours truly. Her grow consisted of only 4 plants, split into two groups of 2, that were about 3 weeks apart from each other. The plants were in our 2' x 4' aeroponics tray, and only received LED light during this bloom cycle. You will notice a few left over HID's hanging in the background in the photograph, but that's all they did the whole time. They've since been removed and put up for sale.

Anyhow, back to the grow at hand. The first pictures are from 8-22-09, when the oldest plants were about 3 weeks into bloom. The two larger plants are Strawberry Cough X White Rhino, and AK47. The smaller plants are Ice, and AK47. The nutrients used for this test were Humboldt Nutrients Master A & B, Ginormous, Cal, Mag, and Molasses. The CO2 was at 700ppm during the first 4 weeks of bloom, and varied between 700-1100ppm during the remainder of bloom. Room temp was a steady 80-85 degrees, and the humidity was between 40-50%. Anyhow, enjoy the first picture, cause there's lots more to come.

Can't see anything

My friend added an extra 126W to the group today, giving her a total of 5 now. So for the last few weeks, she'll have 630W LED in total spread out over her area.

This next set of images shows you how our lights work. Some people were mistaken, thinking that each plant had access to 630W of LED, when this simply is not the case. Each 126W has a narrow footprint, as you can see below. The first picture starts with 4 lights on, and then we turn them off one by one.

The following pictures are mainly for comparison purposes. To give you an item to compare to the buds, so you know how big they are. We show bottom buds and top buds, so have a look.

So I took a vacation, which is why there is a lapse in photos. When I got back, I found out that the AK47 plant had been chopped about 1.5 weeks too early!!! So it doesn't show up in these pictures...

So here are the results from the AK47 that was chopped early: 7.5 ounces dry weight.

My friend had some AK47 left over from her previous harvest with HID, so we found two buds nearly equal in size, one from LED, one from HID and compared them. You'll notice that the two vary in weight by 40%! The denser of the two was grown under LED.

In these photos you get to see us weighing out the AK. Just subtract the number in the final photo (the scale measures pounds, then ounces, etc...) from the second to last photo and you get the 7.5oz's listed above.
