I have researched and agonized over GLH290 for months now but I will hold off from purchasing until the 2011 V.2 models prove themselves in journals. Currently I have 2 Diamond Series 300 from Advanced LED in transit. I plan to put the panels in a DR90 tent.
whats up guys how far do u guys keep the leds from ur plants and whats recommended? stay stoned my friends
what do u guys think of this new 7 band from htgsupply? 381-400----------------- start of visible light spectrum. Process of Chlorophyll absorption partialy begins. UV protected plastics block light below this range. 401-520 nm------------ This light includes violet, blue, and green bands. Peak absorption by chlorophyll occurs, and strong infuence on photosynthesis occurs. (PROMOTES HEALTHY VEGITATION) 521-610 nm------------- This range includes green yellow, and orange bands, and has less absorption by pigments. 611-720 nm------------- This is the red band. Large amount of absorption by chlorophyll occurs, and the most significant influence on photosynthesis. (PROMOTES FLOWERING & BUDDING) 721-1,000 nm---------- There is very little to no absorption here. Flowering, and germination is slightly influenced on the low end, at the high end of the band is infrared which is heat. Growing Plants with LEDs | Mihaela Lica
