these plants went through veg and 2 weeks of bloom with 1k hps and some leds... i ran out of room for the 1k, close enough to burn. they will finish their lives under 920 led watts. anyone thats interested the link is in my signature.

Hey Bro

you mind me asking how much you paid for that LED? Is that a square one? i have a small round 90 W'r. it works great for me but i have a small op going on - nothing too big as room is at a premium

peace:bigjoint:

I have two 120 watt led panels from Growledhydro. They are the 3 watt 11 wavelength newer ones. They are for sale for $320 for both, shipped. They retail for $350 a piece, I received a second one for free cause the first one has a dent on top and one of the three fans in it does not work, but the light works just as good as the other one, and does not get any hotter. They work fine, I just don't like them, and would like my money back out of them is all. If you want pics of them, pm me, be happy to send.

Hi,

Have been trying to get a very small personal medicinal system setup. I have a closet thats aprox. 6 ft tall, 1 ft deep, and 3 ft in length. I seperated a 2 foot area at the bottom for my 24 veg and intend on using the upper cab space for bloom. Ideally would like to have 3 smaller girls bloomed out every month or so. I cuurrently have a 150 hps in my top cab, a couple cfl's in my lower area. I'm having no luck at getting things off the ground thinking heats a major issue. So contemplating on switching to either a ufo 90 watt or the glow panel 45. Any suggestions or thoughts? Would appreciate it.

dont use it dude the uv is to strong use a repti glo 5.0 its an iguana light my iguana lives in my room and at first i couldnt figure out why my resin production was going up i took out the uv light and it stopped put it back in bam there was the resin again obviously over a couple of grows 2 to be exact one with one with out well untill the end i could already see the diff but the 10.0 is like desert uv u will burn your plants try 5.0 it what i used before i got the led with uv in them

things i've learned after research...

spend money on a light with 660nm reds, not the 630's. it is slightly more $ but better quality light.

you can use the blue LED lights during the dark cycle and not affect flowering

do not buy a light with IR LED - it is simply heat, waste of wattage

UV, violet or white, LED are marginally beneficial.

LED is more efficient for VEG than MH.

LED nuggets have been reported as being more dense than HPS, but with a lower yield. However every day that passes we learn more about the ideal balance of LED.

Perhaps its best to have 90% blue/10% 630nm and UV for veg

and 90% 660nm/10% uv and blue for flowering would compare to HPS flowering

Sup guys. I have two 120 watt led panels from this site, http://growledhydro.com/index.php?main_page=product_info&cPath=0&products_id=5. I do not like them, and want my money back. I paid 375 for one panel shipped, it did not cover the area he stated on website, so he sent me another panel for free. I am willing to sell both for 320 shipped. I have pics of the lights if anyone is interested. No I wont sell just one, they both go together, 2 for 1 folks! PM me if interested.

This is my 3rd LED grow. My first two were LED + CFLs. This is my first time with LEDs and HPS combined.

Very beautiful setup! The LED's look's a bunch of UFOs ready to steal your crop's, lol. What was your temps like in your grow tent? I was thinking about doing a similar setup.

It's constantly around 68-75 depending on how warm it is outside. I'm not using an AC, just an intake connected to the hood and one oscillating fan breezing the room.

However if you use the UV-B reptile 10.0 for short bursts, for 5 mins in the morning 10 mins mid day and 5 mins before lights off during the flowering phase (when your buds are bulking up) the UV-B light will attack you plant, BUT!!! - the plants defence mechanism is to cover its self with THC! and will give you up to 30% gains in CBD + THC, ill post details from the text on my thread. I will be doing this on my next grow and displaying my results as I go :) - STELTHY:leaf:

PS/ BE VERY CAREFUL AROUND THEM AS IF YOU COME IN CONTACT WITH THEM THEY CAN GIVE YOU CANCER FROM THE RADIATION! - STELTHY!

UV-B RADIATION EFFECT ON PHOTOSYNTHESIS, GROWTH AND CANNABINOID PRODUCTION OF TWO Cannabis stavic CHEMOTYPES: by John Lyndon, USDA-ARS, Southern Weed Science Laboratory, P. O. Box 350, Stoneville, MS, 38776, USA: Alan H. Teramura, Department of Botany, University of Maryland, College Park, MD, 20742, USA., & C. Benjamin Coffman, USDA-ARS, Weed Science Laboratory, AEQ, I, Beltsville, MD, 20705, USA: Received August 29, 1986, accepted February 24, 1987: page 201 Although the mechanism is unknown, a relationship exists between cannabinoid content and the attitude altitude at which C. sativa is grown. Mobark et al., (197 suggested that the high-altitude environment was responsible for an increased population of propyl cannabinoids in plants grown in 1300m. The average total cannabinoid content of wild, mature (flowering) Indian C. sativa from elevations between 250m and 1000m was 2.43% (by dry weight); between 1000 m and 2000m was 3.01%; and above 2000m Was 1.39% (Turner et al., 1979). The cannabinoid content in four out of five of these mature Indian C. sativa variants decreased when grown at sea level in Mississippi, USA. One likely factor which may be of significance to cannabinoid production in both high-altitude and tropical environments is ultraviolet radiation. page 202 Pate (1983) reported that C. sativa populations originating from high UV-B environment contained little or no cannabidiol (CBD) but high levels of delta 9 - tetrahydrocannabinol (delta 9 - THC), while the opposite was true for population from low UV-B environments, and proposed that the two distinct C. sativa chemotypes (drug and fiber) evolved as a result of selective pressures brought about by UV-B radiation. Fairbairn and Liebmann (1974) reported that the delta 9 - THC content of leaf tissue from UV irradiated greenhouse-grown drug-type C. sativa was 23% greater than non- irradiated greenhouse-grown plants. However, neither the spectral distribution nor the daily dose of UV radiation . The objectives of this study were to test (a) The physiological and morphological insensitivity of both the drug and fiber types of C. sativa to UV-B radiation; and (b) to correlate this insensitivity with a change in production of delta 9 - THC or CBD in drug and fiber type plants, respectively. Material and Methods Page 203 Results....Only the delta 9 THC content in leaf and floral tissues of drug type plants increased significantly with UV-B radiation. page 204 Discussion page 205 The results presented here indicate that both types of vegetative C. sativa are physiologically and morphologically insensitive to UV-B radiation. The increased level of delta 9 - THC found in leaf tissues upon UV-B irritation may account for this insensitivity on the drug type plants. However, fiber-type plants showed no comparable change in the level of CBD which has similar UV-B absorption characteristics). Thus, the contribution of cannabinoids to the UV-B insensitivity in vegetative C. sativa is equivocal. Perhaps the background levels of CBD present in the fiber-type tissues were sufficient to protect the plant from UV-B radiation. Alternatively, other UV-B absorbing compounds such as flavonoids may account for this UV-B insensitivity. Flavonoids are the principle pigments associated with UV radiation greening in plants . Barrett et al (1985) reported the concentration of Cannflavin A (a flavonoid from C. sative) was similar in drug and fiber type leaf tissue, whereas Gellert et al (1974) reported relatively more flavonoids in drug than fiber type plants. Whether the quality and quantity of flavonoids in leaf tissues of the chemotypes in this study were sufficient to account for observed UV-B insensitivity was not determined. It should be pointed out, however that one should be cautions when extrapolating from greenhouse to field conditions in UV-B studies. In addition, when considering the distribution of C. sativa, one cannot overlook the fact that it is one of the oldest cultivated plants known to man. Thus, its present distribution may possibly be an artifact of man's cultural practices. In conclusion, the delta 9 THC content in leaf and floral tissues of greenhouse grown drug-type C. sativa increased linearly with UV-B dose. Other cannabinoids in drug and fiber-type plants were unaffected by UV-B radiation. Both drug and fiber chemotypes were physiologically and morphologically tolerant to UV-B radiation.
