So over the past 2 months I've racked up close to 1,000 USD in investments on my new hobby. I've build a box (almost finished), bought primo seeds, lighting, balast, alot of stuff, nutes, hydro system, etc, etc. I seem to have a few more things I need. Now I know I can obtain all of these through time. But for now I need to be as thrifty as possible. I'm still short some Co2 setup and since I'm going from soil to hydro next cycle, I need a EC reader. Any links or advice on obtaining a cheap one??? Possibliy digital??? Thx, Blaze
I just purchased a cheap digital TDS meter from Ebay... I'm not sure but as far as I know it gives the same result as EC as long as you have it calibrated with NaCl http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=300279613306
Get an Oakton TDS UltraBasic meter. Best meter for the money. Stay way from the cheap yellow Milwaukee ones or cheap Hanna ones.
