more UV light will produce more THC, but, most importantly, make shure the plant is very thirsty and dry when you harvest; that will force your plant to pump out THC before you harvest it.

r uv lights florecent or juss tha regular light bulbsin lamps?

[newgroweroldsmoker]

what dylan suggests is the use of MV lamp (mercury vapor)....he's right.....i've read about it in an older thread i think in this forum......i am not sure though the lighting schedule for this lamp....i think a couple of hours are enough in conjuction with the hps that you propably are using right now......not sure though.....anyway the MV lamp is the one you need!

but using a 100 watt living room lightbulb will that make me have a good harvest

[newgroweroldsmoker]

you mean 100 watt incadescent bulb? if yes......the answer is no....make some research on the net for Mercury Vapor bulb.....it comes in 100 watt as well.....you must use it along with an HPS bulb....on it's own can't really achieve much due to low lumens emitted...plus the uv rays it emits are harmful for the skin and the plants...for this reason it is wise to use it only a couple of hours a day.....only for plant optimization....not for growth or vegetation.....another thing, with incadescents you should not expect much as they are high in wattage but low in lumens....ie....to get 58000 lumens (my 400 watt HPS) with incadescents you will need around 44x100 watt bulbs....that is a total of 4400 watts.....with 4400 watts of HPS you can grow around 90 or more plants to full maturity....plus the HPS provide more or less a full spectrum light, can be used all around the plants' lifecycle while the normal incadescent bulbs can be used maybe only for vegetation aka the first 2-4 weeks of the plants' life.....i hope i am right in everything i said so far and have not confused you......anyway in the case that you speak abou fluorescents, common use fluros, you can use them for vegetation......however there is a new generation of fluoros called envirolites....they come in two different types...one rich in blue spectrum (for vegetation) and one rich in red spectrum (for flowering).....the good thing about these bulbs is a:that with 125 watts of output, they reach almost the lumens emitted by a 400 watt MH (Metal Halides:rich in blue spectrum, used for vegetation) which makes them a good alternative for vegetation and b: they put out minimal heat and thus you can approach them closer to the plants without having the fear of burning the plants.....ie the minimal distance for an HPS lamp is one foot/30cm (250 watt) and the number goes right up as the watts increase ie at least two feet/60 cm for a 1000 watt HPS.....hope that info helped you

yes, listen to newgroweroldsmoker; it sounds like he has been doing his homework on lighting! man, i didn't even know that incadescent bulbs were that low in lumens. i knew they were inferior to HID lights but damn.

actually, if you go out and buy a reptile light they are VERY rich in UV-B light, which is what the plant needs to produce the thc more. Dont use it for more then 4 hours a day MAXIMUM! you can kill the plant with too much UV light. Mecury vapor lights arent that good, and really are only good as a compliment to others. Also flush the plants 2 weeks before harvest. This will give the plant a cleaner taste, and rich nutes. During budding be sure to use less nitrogen as more nitrogen means less THC. But that doesnt mean stop using nitrogen. Along with turning the lights off 1-2 days before harvest, and not watering for a couple days.

NO reptile lights are rich in UVA. The reason why HIDs like MH and HPS have little UVB is that the manufacterers are required to have low UVB output.

UVB is DANGEROUS. With only a few watts you can get sunburn in minutes under one of those. Medical facilities use UVB for certain treatments. It mutates DNA, it causes skin cancer, it causes blindness.

Here's a link from reefermans board

ANd just a disclaimer, oldtimer, the guy talking about the UV on that link doesn't reccomend using them.

he says
"So IMO, again - if you want to do it right and saftely, do it outside. I answered the question of the what the right UVB lamp is, not because I would advise others to do it(as I wouldn't do it myself), but as a guide to show that it could be done if one was crazy enough to do it."

IMO start with good genetics, keep them healthy and your pot will be plenty potent. If you want more potency, smoke another joint, or make some bubble hash. Pot's been growing indoors just fine without UV supplement, I'd be willing to bet that most of the pot in Amsterdam coffee shops are grown mostly under 600watt HPS lights since these are the most popular lights over there due to efficiency.

Dropping humidity will cause them to frost up a bit more and you won't go blind doing it.

Peace
