Almost every professional production greenhouse disagrees with you, at least the ones I've been in from Morocco to Australia.
Even the company making Sativex uses PURE MH all the way through for cultivating their cannabis. Why? The company doesn't like etiolation (most commercial operations hate it,) and green wavelengths interfere with the production of THC. This I have noticed as well. Plants under led are way more potent than the same strain grown under HPS.
"20 hours for veg"
Very few places on the planet even get that amount of light and the best cellular division rates occur after 5 hours of darkness, while the majority of nutrient transport happens. |
20 hours of veg,
exactly, we force the plants to grow, i know for a fact that 20/24 lighting is the best for veg, who cares what nature does, the plants are forced to abide by nature in the wild, we have been chopping and changing the hours for 23 years, i also know that led is not up to scratch with a 1000w met hal, or 1000w hps, you can talk to the ends of the earth, i know what i know. i think it will be about another 5 years before low wattage lighting reaches a level that will surpass high wattage, if possible at all. i would say maybe by 2015 at earliest, if low wattage led lamps were that good, the whole cannabis community online would be very excited indeed, and i imagine that to be a lot of people.
i am not here to argue with you about your amazing led
lights, the led Illuminator pro 350 watt cost $1000, and that is way over my head for common sense considering you get a few low wattage lights and that is all. i am here to find help with hydroponics, and the matter is finished.
you use led, i use hid. fine.
