im sure everyone has herd about those but how much better is my question?
i guess hook them up and find out how much better they are!!
is there a tube thats like a T 9 T 10 T 11 T 12 i would like to get my hands on the strongest flurescent
i think the more fluro's and cooler it is the plants grow better atleast me and my friends plants have been reacting and growing atlot faster at 78 degrese and these T 8 tubes and they are the fat ones!
it doesnt matter what anyone thinks now because the plants are growing way faster now withthese tubes and ive also been noticing were there alot of new sprouts all over to the plant!!!!!
The T number mainly denotes how wide the tubes are, in eighths of an inch. T8 = 8/8 = 1 inch in diameter. T12 = 1.5 inches. The brightest ones are actually T5 (5/8 of an inch) though, because you can cram them really close together for more total light.
damn i thought the t 8 were better so the t 5 are that sucks but i still can use these t 8 bulbs right?
yeah. personally i use T12s just because they're cheap, i have the lights already, and the amount of light they emit is adequate. The only reason T5s are better is that you can fit more of them over your plants for more total light. They are a bit more efficient as well, but the difference isn't that great.
I second the use of T12 also ... when I was using fluorescent tubes, I did the math, and just didn't see the 'lumens per dollar' by going to the more expensive T5 ... maybe prices are better these days, I don't keep up with it ... you can do a lot of comparison shopping here: Light bulbs, Rope Lights, Halogen and Fluorescent bulb - 1000-Bulbs - The Light Bulb Superstore
by clicking on the details buttons, etc., you can learn quite a bit ... :thumbsup:
i have 4 t8 tubes now with 4 42 watt cfl's i think thats good for only two or is it? im somewhere around 150 watts and 7000 lumens
i no one thing when you open the top of the box and look in there its brighter than outside and after looking in there everything looks dark as hell
im sure youve noticed the inside plant is a hole lot healther aint it.
every thing i say here is a lie just like the user name on the internet and just a lonely person who likes to talk about everything im on message boards everywhere
i also have never really tried growing anything ever just bored always!!!!!!!!!
Khronik and Reaper: You can find ballasts and bulbs for t8s that are just as cheap as t12s and smokinbuds has made a good observation they seem to penetrate the plant greater than t12s.
For my next vegetation, I'm probably going to build my own T8 fixture out of wood. Still, the cheap shop lights I have can only be used with T12 bulbs, and any other lights are twice as expensive as these.
Did you check ebay for ballasts my buddy got a sick deal when he bought 10 at a time
Khronik if you buy the t8 ballasts on ebay express you can get 10 for $30. Then all you have to do is swap the t12 ballast in your old fixture with your new t8 ballast there same size.
T12tubes are the cheapest, as are the mounts to get them set up. I work at home depot. for a shoplight, that holds 2 T12 lights, its 8.69, and plugs into a wall outlet, or timer. the bulbs are around 9 bucks each. the T12's come in a few wattages, from 32-40 which is what the shoplight can handle.
Those aren't the bulbs you want. The $9 bulbs are aquarium/plant lights, which are actually not as good for vegging cannabis as the cheap $3-4/bulb 'cool white' t-12s.Quote:
