Uh huh. I believe you. Right now the CFL's provide some warmth during this cold month.Hey man just a quick word of advice, i recently started this fine hobby myself and trust me you will eventually go for bigger lights.. i started with cfls and even before i finished my first gorw i got a 150 hps, now on my second grow and i started with the 150 now im on 400trust me you WILL want more, running 8 cfls produced as much heat as my 400 man i actually use them now to raise heat if it gets a little low
dont get me wrong you dont need to rush your lights u can veg fine under the cfls ive seen so many people do it, save ya some cash but for flower u will want the hid system definately.
you only need to give them at this stage bout 60ml of water a day, no more because overwatering is the main cause of new growers getting things of to a bad start , i still have problems with watering cause i find myself wanting to care for them too much all the time , also get one of those thermo/hygro meters you want your Relative humidity pretty high right now cause well their roots are only tiny little baby roots and they love high humidity cause well they take what they need through their leaves.
A couple of questions, Serving Size. Will the ballast you linked to run more than one HPS lamp ? I'll need a "big socket" for the lamp, right ?
nah ballasts only run one light at a time .. im not sure if you can hook up lets say 2 500 to a 1000w ballast but im pretty sure id dont work that way.. youll need an e40 socket for your hps.
Thanks man.
That is so cool!
I started with two hardware store Incandescent flood lights sold as grow lights, then 2 floros, then a 150W clear glass, then 400W big bulbs, then two 400s, then 600s, now 1Ks. 1000 watt metal halide for veg and 1000w HPS, two 4ft 54W UVs, and two infrared leds on timers for flowering. you can go a little "mad-scientist." But you have it right. Simple and easy.
This is also, so cool!
It IS a weed. It's GONNA grow!
(new house new setup) That puts my grow room electrical usage right around that $70-$90 mark per month. I harvest 3-5 plants per month getting roughly 3-5 ounces per depending on strain. That is a lot of smoke for under $100 per month!!! 
Ah ! A man of experience. Thank you.Welcome Camo Hat!
Another retired grower here! Like others have said, you will be upgrading lights soon enough!
I started out with a 4 foot florescent fixture then upgraded to 5 of them. After that I upgraded again adding another 5. After that, I purchased a 600 watt HPS and used the florescent fixtures for vegging only. Soon after I added another 600 watt HPS. Now I use the two 600's for flower and 5 florescent's for veg.
I might have a whopping $500 into my setup now with fans and ducting added. I grow way more than I could possibly smoke and always have at least a pound on hand. I give away a bunch of smoke due to only being allowed 24 ounces on hand at any given time. ( I am a medical card holder and live in a recreational state)
I reuse my soil so I have not purchased any in well over a year. Same goes for nutes, I have not purchased any in well over a year as I do not use them. I use water only!! As someone mentioned, get and read the book "Teaming with Microbes" and get knowledgeable about soil. I went this route because the only thing I pay for is electricity and water which totals a whopping $70-$90 per month depending on temps. Remember I am retired and on a fixed income....
Good luck in your adventure! I will be watching this thread to see how things are going.
Best advice I got here was to not be a helicopter parent and develop a little patience. There's no instant gratification.
Patience is a virtue, it's the only one I have left.
I know what you mean,dude....retired also
