help needed in the first grow

Ok this is my first grow and my friend is giving me four female plants which are at a stage of flowering (in their 1st week of flowering still) i am not sure what should be the most effective light system to set up(in a small closet) in $300. Acording to the research i did i found 2 different light systems.

246W Spectra Max Full Spectrum 24000 Lumen 2FT Grow Light - Plantlighting Hydroponics



and the other one is:



Roselle Area New 600 HPS SuperSun Grow light System





I beleive with the second link of 600w sodium bulb; i would have to set up some Fluorescent light on the sides and some reflectors too if i am not wrong?



All I want is to get the best light in $300 which will give me the best quality and the most quantity out of those plants.



Another thing i was wondering about was that how much bud four plants would give out normally. acording to my knowledge four plants with one of these lights should give me at least 2 pounds if i am not wrong?



Thank you guys for your time!

Just from what Ive read:

Go with the 600watt HPS. You can either get mylar or paint the walls white, both of which are extremely efficient to help reach under the main canopy for reflecting light.

Also, you can still lst your plants during flowering, just be extremely careful as not to snap the branches. Read up on the LST thread, there have been q's like yours where people just started lst into flowering.

600 watt hps. and two pounds from 4indoor plants is a major push not to mention all the variables

Also how much are you going to invest in your ventilation system...you don't want Heat issues ....
Good luck

yeah heat could be a problem. here's a link to a really good deal on a 400W MH/HPS system. click on products. they also have a 600W. after shipping i think its like 330.00.
