top/fim, LST HAHAHAHA lost me there steve
ARHH found LST (low stress training) coundnt i use a SOG for this !?
Lol, I knew what it was, but I didn't know that's how it got it's name. Learn something new here everyday. Thanks Steve!FIM is short for F*** I Missed, coined by a grower that was trying to top but didn't get the whole top shoot and only clipped about 2/3rds of it.
Subscribed. Definitely looking at LED's for when I get started here over the winter. Looks like a bit of money invested up front is going to pay off nicely in reduced electrical costs and heat load, provided they grow well (and they certainly seem to be!)

The heat from these is very low, I posted a graphic of the light and what the operating temps were from several locations using a laser thermometer. I'll have to go back and find that. If I recall, the hottest was around 100deg f on top.Steve, you have probably already answered this question but I want to ask it anyway:
What about heat from LED's compared to that of HPS? How significant is the difference? I am just wondering when the up front cost of the LED will cross the operating expense curve at the point where it finally gets cheaper than running traditional grow lamps with the same wattage. That would be a nice analysis that can be easily visualized on a graph with total cost on the y axis and time on the x axis. Each curve would start at the initial cost on the y axis and move over time. Operating Cost could be averaged each day for each light type and could be derived from number of kwh used each day by each system (air conditioning, fans, ect). There could be two curves, one for LED and one for a comparable HPS. The time it takes for the LED curve to cross under the HID curve can then be calculated in current dollars using a discount rate of your choice...probably very low today since interest rates are so low on short term bonds. Thoughts?
I would LOVE to see an analysis like this done on a large scale to see how it might benefit commercial growers. A smaller scale grow might be able to be extrapolated but might not be very accurate but the data would be invaluable none the less.
