Can i use 2 t12's

i have two seeds that finished germinating, and i went to lowes and bought a 4' shoplight and 2 daylight (40watt, 2325 lumens, 6500k, each) will that be good to veg them for a 20/4 grow schedule?



*this is my first grow, and cant spend alot

Get two or three with all 6500k bulbs and you will do fine

those will work flower with a 150w hps or 400w hps either will work in a closet

yeah its in my closet with all white paint

i would try cfl's. i started with t12 and relized very soon it was a bitch to keep the light evenly spread. i went from 3 t12 fixtures to 9 cfls and noticed better growth almost instantly..imo

t12 are good for cloning only

U might be able to grow it in fact it is going to grow but will take forever to flower and the yield will be crap. You can get a good 400 watt on the internet with timer, drop cords and boths bulbs for 140 bucks these days.

they have sprouted and its developing its first node, and i only have 2 plants over 4 feet of light so i think it should spread easily

save up 50 bucks and get those two plants covered with cfl. youll get a better spectrum of light and way better coverage. my plants looked like this after a week of t12's and if you have 4ft of length in your grow room, you could split that into vegging amd flowerimg sections. why not kill two birds with one stone?after i switched to cfl this was the same plants a week and a half later

forgot the other one

I'd agree that T12 can work for cloning.

But you definitely "can" grow whole plants with them. In fact, in the 70s MOST indoor growing was done with T12 fluorescent lighting. The problem is the tubes are bulky and they're just not that efficient compared to more modern tubes (let alone HID lighting).

If you want to go the "cheap fluorescent" route, you can go with T8s.

CFLs can work too, and are probably preferable to T12s, but its hard to get good reflectors for them, and so in reality, they're not nearly as efficient as the numbers on paper suggest.

Edit:
CFLs are probably the cheapest way to go, at least in terms of STARTUP costs.

My plant is a week old and it looks exactly the way the first picture does, and I'm satisfied with it since its only my first grow. Now I'm just wondering how much I should expect it to yield.
