Hey guys need some advice on this system

Has anyone used this before? Let me know. Or im thinkin about makin my own. Also what nutrients can i mix in the water. New to hydro and going to try it out. Using soil i have had some problems. http://www.nationalgardenwholesale.com/ngw/gardening_supplies.aspx?request=GH_WATERFARM_COMPLETE_SYSTEM&title=Tray%20/%20Reservoir%20/%20Grow%20Systems&type=product Also where is a good local place to get rock wool? menards? lowes? or do i have to buy online? Also do u guys recommend Full water all the time or a schedule for water flow? Also I bought mazar seeds online from the majuranaseeds.nl site dunno if that helps.

BUMP because I am itching to buy it. Saw it in a store today for 56$ usd. Anyone please. also please check out my new grow first time at https://www.rollitup.org/newbie-central/335071-first-time-growing-ever-well.html#post4220557 any advice appreciated

dont buy that. you could make your own way cheaper .

Diy it rocks

maryland hydro, green coast hydro or a local hydro shop if ya have one. MAryland hydro sells everything you need for the waterfarm DIY kit for 13 bucks, you can get your nutes and rockwool there also.
