What kind of Nutrients Should i use

Im just using a little 400 watt enhnaced spectrum hps bulb with thextra blue in it. I will go to a 600 watt hps when 12/12 comes around

can we use general hydro nut for soil?

yes you can willard

FF if i get a 400w MH lamp will it speed up my growth? I'd assume it will since its has more available watts per sq. ft.
thanks

Yes it will get a switchable digital ballast that way you can run and mh or hps bulb in the same unit and the digital run cooler, uses lesss lectricity and weighs like 5 lbs compared to 30 lbs for some of the older magnetic units. Maryland Hydroponics has 400 watt digis for $99 or 600 watters for 119. Think the 400 watters maybe out of stcok but you can mail them and find out if they have more in yet. www.htggardensupply.com has som affordable whole units also. a 400 watt light if on 24 hours a day all month only adds about $20-25 to a bill and when its 12/12 figur less then 15 bucks

I'm not worried about the bill thats not a problem just trying to save up enough so i can get one, im in-between jobs right now aka unemployed so ive just been doing odd jobs... i should have a job soon though
