Hey, choadey62. You can definately bud those ladies 4 cheap! You will, however, have to eventually buy a better light... BUT, you dont need an expensive one right now! And you dont need expensive chemicals. Just wait till they're older and give them some organics. Much cheaper!
In order to give those ladies the full spectrum during budding, you're gonna' have to get a MH/HPS light. You've got a couple of months to save up for something like
this. But like I said, you dont have to worry about that, right now. The link I posted for you, is the cheapest light I can find for you, right now. You dont need that light just yet. For now all you need to buy is a cheap fluorescent setup from Wal-Mart. The hundred dollar set-up can wait till' you need to flower.(Couple of months from now) When you go to Wal-Mart to get the hood and 4foot fluorescents, pick up a warm white, and a cool white bulb for each hood you buy. You(or your mom) wont spend more than 20 or 30 bucks on the whole setup, and you'll have the light that will veg them until your ready to start flowering them with the MH/HPS.
For right now, if you want to grow those babies to be big beautiful ladies, the first thing your gonna' have to do is put them in seperate cups. GENTLY dig them out with soil intact, and put them in plastic party cups. If you leave them in the same pot, your roots will tangle.
Good luck, man!
...And just because he had an expensive setup doesn't mean anything. The setup I have is as elaborate as any. With the right amount of love and care, you can grow ladies just as big and beautiful as anybody else! here's my current grow room... Honestly... You dont HAVE to have a room as elaborate as this.
