you need it to be an inch or less, for starters, and it could do to the end, but you're end quality won't be very good, with a not so great yield

I believe they have them, while they are not designed for horticulture i have seen people using them with success.
High Tech Garden Supply has a 400w budget system for 120$.

i went to my local lowes and home depot stores and they didn't sell the ballasts for hps. they had the lights though. i would suggest moving to a compact fluorescent lighting. MajoR_TokE is using cfls, you can follow his grow journal here. Check out this kick ass post by Mogie that explains cfls too.

BASIC INFORMATION
Compact fluorescents are close relatives of the 4ft tube fluorescents, commonly used in shops and schools for their white, soft light that does not cast any defined shadows. These lights are long tubes, usually 4ft long, filled with a gas that releases a photon of light when excited by electricity. The electricity is passed through the tube from the metal sections at either end, thus exciting the gas within and releasing photons of light. These lights must have a 'starter' which gets the light going initially, unlike incandescent which can just be turned on and off without one. Regular fluorescents usually emit 18w of light per tube, and cannot be plugged straight into a wall socket.
Compact fluorescents, on the other hand, are made for use in regular light sockets, and can easily be installed by anyone with basic handyman skills. Compact fluorescents are usually around 8inches long (not including the ballast, which usually adds about 3 inches to the total length) and emit minimal amounts of heat from the globe itself. Most of the heat emitted from a compact fluorescent comes from the ballast. These lights are usually between 8w and 27w, although some variation may occur between brands and uses.
The main reason people choose CF's over regular fluoro's is their compact ability! They are very 'movable' and can be positioned almost everywhere. They put out MUCH more light than their bigger cousins, while using only a fraction of the space.

NON-CULTIVATION USE OF COMPACT FLUORESCENTS
If you're running a large grow setup, and you're concerned about the spike in electricity, replace your regular light bulbs with compact fluoro’s around the house! They give off the same light, using only a fraction of the electricity. If you're running a HID light, and the electricity increase could kill you financially, or you're just worried about LEO, it might be a good idea to replace incandescent with compact fluoro’s. As an example, a 100w incandescent uses most of its energy giving off heat. If you replace all these 100w incandescent bulbs with ~20w energy saving compact fluoro's, you can dramatically reduce your energy bill, and help the environment at the same time. In fact, I recommend changing all your lights to CF's regardless of your growing situation, as they will save you $$ in the long-term, and save the environment.
The advantage with these lights is that the conversion from incandescent isn't complicated! Simply un-screw the old bulb, and screw in a compact fluoro! Done! You're on your way to energy saving paradise!
THE USE OF FLUORO'S FOR GROWING CANNABIS
Every grower has, or still uses these lights. Although they don’t even come close to the results from a HID light, they do however provide a cheap alternative for a newbie 'dabbling' in the fine art of growing. Instead of spending hundreds of dollars on an HID light, a newbie can purchase a compact fluorescent for a few bucks, and still have money for a coffee on the way home.
These lights are also excellent for starting seedlings and clones, as their cool light will not dry out the soil as fast as an HID. They have a low intensity, and are gentle on newly germinated seedlings, and are great for clones as they wont dry them out or give them too much of an early blast.
Compact fluoro's are also great for stealth grows, as they can be kept about 1 inch from the plants, and do not require extensive heat ventilation due to their warm operating temperature.
WHERE CAN I PURCHASE THESE LIGHTS?
Most lighting stores will sell them, but watch out, prices are very different depending on what type of shop you get them at! As lighting shops only sell lighting equipment, their prices can either be high or low, it really depends on the type of lighting shop it is. A designer lighting shop may end up being much more expensive, as they tend to be more directed towards the upper-class designer type customer, which extra $$ to spend. Hardware’s sell them, but their variety of lights is usually limited. Electricians, and assorted electrical shops will sell them, and this is most likely where you will get the best range and the best prices. My advice to you is, shop around! You wont regret it when you can save around 30% per light.
WHICH TYPE OF COMPACT FLUORESCENT LIGHT TO CHOOSE
For anyone growing cannabis, it is pointless to buy a weak light. Given the option of 8w, 15w and 27w, you would be stupid not to buy the 27watt, as they are more or less the same price. Compare the lumen output of each of the bulbs, different 27w bulbs may have different lumen outputs (depending on the manufacturer) and as with everything, the more lumens the better. You will also be given 2 options, the screw method of fitting, or the bayonet method (push and turn). My preference is the bayonet fitting. Make sure that you choose the right one for your socket! Also, do not choose a regular compact fluoro. Pick the one with the energy saving feature (will be explained why later on in the document). Now, for vegetative growth you should choose the 'cool white' light. This is also acceptable for flowering, but a 'warm white' light will be better as it is stronger in the red end of the light spectrum which is more suitable for flowering.
INSTALLING YOUR COMPACT FLUORESCENT
Now, this is extremely easy. As these bulbs fit normal light fixtures, you can just dismantle and old lamp to get the cord, plug and bulb fixture. This is ready made, as all you have to do is plug the cord into a wall outlet and screw in a bulb (with the power turned off, of course). This requires no electrical knowledge at all, and is the easiest way to get a cord suitable for a compact fluoro. The cord is simply removed from the lamp, and you are ready. If you feel you are not up to this task, or you do not have an old lamp ready to be destroyed, you can easily make one of these cords with basic electrical knowledge. Hardware’s and electricians will sell you the cable (you'll need at least 1 meter) and the fittings for the wall socket and the light. Just tell them you're making a lamp for pottery and need a few cables to make up yourself. The parts are cheap, and you can save $$$ this way. If you have any queries, the electrical store will know exactly what type of cables you need etc, and will be more than happy to give you instructions on how to put it all together.

yup, that's the post mogie!
Its been 24 hours since I put my six plants under the 4' T12 cool white tubes (40 W each). I have the light less than an inch away from the tallest plant. They are about 7-8 days old and are about 3-4 inches tall. Some stems are purple and some are white colored. They have shown the least amount of growth over the past 24 hours under the new lights. I had them under a Reveal 60 watt regular bulb. They look healthy but one of them is starting to get tiny brown spots on one leaf but I'm not too worried. Today I bought a ph kit and the water I was using was around 8. I bought some distilled water that is about 6.8 and I put some ph down in it to about 6 to compensate for the high alkaline tap water I was using. I think they may have had too much water so I stopped watering twice a day and now I'm watering them once a day. Is it too early for nutes? I don't know what kind to give them when they're only one week old. Any help would be greatly appreciated once again. thanks

my plants are similar to yours, a week old, but their about and inch tall. i just put nutes in their drink to night at 1/4 strength. excited to see how it will affect them tomorrow night. also you may be over watering your plants. only water when all of the soil is dry. be careful from watering plants with dry top soil and moist soil on the bottom.

Ugh..I know this was said already, but put the plants as close to the light as possible or they'll be stretched out as hell. My plants are only a week and a half old if that, and they're 3 inches tall already, and the stems are skinny as hell. I had to use wires to hold them up.

to stop plants from stretching simply bring plants closer to lights. also to stimulate stem growth and over all plant health, introduce a fan to your babies.

only an inch after a week? keep the lights on them for 3-4 weeks 24/7 for max veg growth.

guess what the 99 cent store sells moisture meters for a dollar!!!!!!! I BOUGHT ONE JUST TO SEE IF IT WAS ACCURATE AS MY 3 WAY (light, ph, moisture)
and low and behold it for goddamn sure it is.. they have a little garden and hardware area that is killer for a buck. if you need some dumb ass shit its a great place to stoclk up and not hurt your pocket (helps to save some $$$$ for better lights & nutes)
