Are you using 20,000 watts of leds? Man, you better get back to your commercial led grow....
Currently 20k of HID. Actually, at the momment, 18k...a couple of veg lights are not being used. I'm hoping, some day, god willing, with luck, and some breakthroughs, to be replacing it all with LED's, induction, or some combination of the 2. My hopes would be to cutt the wattage to around 13-15k with the same production. The technology to do this is not here yet. I have no illusions that it is. But, with bigger and more powerful LED and induction lighting in developement, maybe we can get there in a few years.
With the current LED technology, it would be finacial suicide for me to transition now. But, to make the blanket statement, as you did, that LED's don't work, is kind of narrow minded. It's no different than the LED fanatics claiming that HID tech is outdated and LED is the only way to go. If you have any ambitions of being successful in this industry, you must keep an open mind. I tell this to myself as much as anybody. I'm pretty old school. I grow in rockwool, and top feed by hand drain to waste. My cuts are rooted in a $3.00 tray with a $5.00 clear dome. I see no reason to change anything on this front. But, HID's have some serious drawbacks. We're in the middle of a heatwave right now, and I spent my day hoping my A/C and exhaust systems would do their job...and they were all working quite hard today. The though of only needed a couple tons of A/C to keep my temps right gives me a hardon. We need new lighting in this industry, and it's looking like LED may be that lighting. I'd encourage you to open your eyes and your mind to what the future may have to offer. I'm not pushing LED's...there's not an LED on the market that can do what my 1000 watt HPS's do for me. But, that doesn't mean there won't be soon.
