what the hell does light wattage have to do with plant maturity?depends on how many watts your light is
I'd go ahead then as you have a lot of plants so you'll have to raise your a light more to cover them all reducing your penetration depth. The handful of runts I'd put under florescent for at least a couple of more weeks. BTW what color is your MH light, 6500 K, 5500 K, 4100 KI have a 400 watt MH. Want to get HPS once able.
if it's a shop light it's 4100 K (or thereabouts) a very poor grow light but it works. A 6500 K bulb will give you lush deep green growth that side branches quickly. https://www.rollitup.org/attachments/cfl-growing/240662d1226605588-5000k-vs-6500k-hortgraph2.gifI don't know what color my light is. Unfortunately it's not a grow light, it is a shop light.
i would run cfl's they work way better then the shop lightsI won't be able to get them much taller than 4 or 4-1/2 ft. Before I'll be to close to the light at it's highest piont.
What do you think the down falls of using this light would be?

you can get a warm white MH bulb for your existing light, although not as good as a HPS it would pay for itself in extra yield over your existing bulb.After this 1st grow I was hoping to get a HPS grow light.
it should, you could e-mail HTG your existing light bulbs number they'd tell you I'm sure.Do you think my fixture will accept the grow bulbs?
If they are pure or mostly Indica I would let them grow a little longer and flower 4 at a time (ratio 100watts per plant) and put the others in a closet with 1 42w CFl or 2x20w CFL per plant about 4 inches from top of each..
