Just ordered the Co2 system parts from GLA online. Saw their ad for 10% expiring Sunday so went ahead and picked out what I think I need. Didn't need the 'complete' system as I am using the controller mentioned above instead of the SMS122. They are east coast so was already past their business hours so I ordered without calling to get more information. Basing solely on reviews and information gathered from other posts.
Brass Check Valve
Clear Co2 resistant tubing
5lb Co2 cylinder
Also added one of the Green Fertilizer Micro/Macro packages.
Credit card statement is going to be -brutal- this month.
