Yeah, the 1000w high intensity discharge lamp is tough to beat, but I went through your latest bud photos for the first time on my mac at home, and it looks a lot clearer what you've done. I'm very impressed with the overall vigor of your plants and the density of your nugs with what you call a 300w light. When you consider that mathematically breaks down to a difference of 700 effective watts, the results you've gotten with LED is astounding. If you look at it carefully, your buds look pretty comparable to mine, just my photos are clearer and my nodes are tighter. And you say you've done hydro before, so I'm sure you know if that was in a bubble bucket, your nugs would be even bigger and denser under that LED. It's a really cool gadget imo. I bet if I just swapped out my thousand watter and big ol buzzing ballast, lined my box wall to wall with say four LED fixtures (one for each side on the walls and one really powerful one suspended above), it could possibly exceed what I've done with MH and HPs. And no heat means perfect, heat-stress free plants and buds. I like the fact that your colas are like kissing the light and your leaves are all lush and picture perfect without any sign of heat stress from the light, or wind stress from the air circulation needed to cool the light. Amazing. I think I'm becoming an LED believer.
Edit:
Oh, unconscious compliment. I said plants, forgetting that it is only one plant. Good job.
