hi what is the difference between T5,T8 and T12

thanks

I know the t5 don't burn as hot as the others, and if someone can tell me what light is cheaper to burn out of the t5 t8 or t12 or i can go with a 150watt cfl

t5 lights are generally a specifically built rig, they house quite a few of the floro bulbs and some people really like them. t5's are the "cream of the floro crop" the t8's are your basic "shop lights" as are the t 12s but they are a bit smaller. t5's are your best bet for general growing. as the others will not be very effective past maybe 2 weeks. its just not enough light. cfls work great. the 26 (actual) watt daylight bulbs are great for veg. if you use clfs Y splitters are your friend. you can put many different bulbs in one main socket. you can grow an entire crop with just cfls/floros but HID lights will out perform them. to grow with cfls you must be creative. you need to build a decent rig that can keep your lights close to your plants. my first decent light set up was a t 8 rig with about 6 cfls mod'd into it.

as for cost, your not going to really even notice floros on your power bill. unless your running like 500+watts of them and then its still not much.

rebelfied ,
please let me know what cfl you went with and if you tell the diff in growth and cost.
what sq ft are you working with?

I am working with around 1.5-2 sq ft with TWO 6500k 26 watters for now until I get further along into veg. After about the 4th-5th week of veg I will switch to a higher wattage.

These(2 x 26w) will put out right around ~3200 lumens for the one plant.

edIT: These are the ones you want!





if you can find a higher wattage bulb just like these I would recommend it. Like said, I am only growing one inside and will have both of the bulbs on it.

when i say be creative with the cfls this is what i mean.. the first pic is of the cfl rig i was using before i switched to 600 hps, it also had 6 U shaped t8 bulbs as well.

the second is my old cfl rig i grew my first grow with the mod'd out t8 shop light. it produced a BEAUTIFUL plant. from which im growing seeds now.

I'm pretty sure the t-5's are smaller in size than the others.

all i'm going to do is clone and veg with the light, so i'm not sure what to go with.
a t5 or cfl's
here are my ops
price for the light?
cost to burn the light?
heat from the light?
growin power(same watt)?
waht do you think is the winner of the two?
