Hi OMM,
you are getting close, to the roof, lol. they look good tho otherwise.edit: that sounded like I meant they are stretched but not my intended meaning.
Let me share something that I think is the real key to getting the most from your led. I see your plants are all natural growth as in tallish. If you start in veg with topping, suppercropping and LST to get them low and wide instead of tall you will have much more uniform developement as the bottom of the plant is less affected by the inverse square law. You might only get one or two plants in your space instead of 3 but probably actually yield the same or better.
^^^ this plant is only 5 inches or so tall, so the bottom is almost the same distance from the light as the top. If the plant was 3 feet tall the bottom wouldn't be anywhere near finishing when the top was ready. Open them up and keep em short. The less than thick growth is my issue not due to topping and training. This is just the pic that best illustrates plant shape for growth under LEDS. With the cfls that LED should be capable enough, imo. It just can't punch light through that dense foliage.
this plant is in my current grow so you can see how it developes during flower, if you care to drop by now and then for a look.
