Why do you have Jebo actinic lights in the first place? They do make 10,000K bulbs that should work for plants. Cheap source
. Yes I believe they are sold in packs of two.
-A pound of KNO3 (nitrate) will last you around 16 months if you were to make doses of 5ppm NO3/day, 3 days/week.
-A pound of KH2PO4 (phosphate) will last you several lifetimes.
-A pound of CSM+B (traces + iron) will last a lifetime. You can get an oz. of this with the sample pack if you find the pound too expensive.
-KH2SO4 (potassium) really depends. Some here dose K regularly, others not. You can does alot (20ppm) or I've also seen very little (2ppm). A pound or two should suffice for the time being until you figure out your needs.
-CaCO3 and MgSO4 if you have very soft water.
A note on CSM. Others and me included have found that CSM+B doesn't contain enough iron in comparison to the other traces. Rex has said this can lead to copper build up if you dose according to iron (better known by PMDD method). The 10% iron chelate should also be ordered if you wish. The 1/2 pound quantity will last you forever.
