Wow....that's almost a record....it's only taken 18 posts before someone starts making it personal.
I've been dealing with heat issues due to the 4 600 watt HPS lights I am running and seriously considered LED's as a cooler alternative. I have not looked into LED's for awhile and each time I do I come away with the thought "In several years this will be a viable lighting solution".
But for now I feel it's an expensive way of growing one or two plants, and less cost effective as the plant count rises.
As for side-lighting.....sigh......let me ask you this....when you surf bud porn and are looking at big commercial grows....do you see any side-lighting? The answer is "no". There's a reason why big grow-ops with unlimited lighting budgets don't use side-lighting....it's because it doesn't help one bit.
I bought into the side-lighting crap a few years ago. I had over 300 watts blazing the bottoms of my plants....do you know how much less popcorn buds I had.....zero....it didn't change a damn thing to the bottom halves of my plants.
When it's all said and done, HID's are still the way to go. Yes, they're hot. Yes, they will spin your electric meter like a top. Yes, there's wasted energy producing un-needed light spectrum......but again I will point to just about any professional grow operation and they are running HID's......because that's the best lighting available.
