why a dim-able ballast? and a dim-able ballast means it's digital. and every digital (and most magnetic ballasts) are from China. is it UL/CE certified? i can find the galaxy brand ballast for $400 full retail.

also, i'm not a pump master, but i can't find a single water pump that list PSI. every single one i see is in gallons per hour. 27 GPM x 60 mins= 1620 GPH. wouldn't the PSI be determined by the length of the line runs and the nozzles used? agiain, not a pump expert. what is the max height the pump will run? i can find a pump at full retail for ~$150.

also, what is the height of each ring? i would assume 12" since there are 5 rings and the unit has a height of 5'. one 1000W HID bulb in the middle and centered doesn't make the unit all that efficient for the top and bottom rings at least (i would assume).
you might be better off with a dual 600W or 1000W as opposed to the dim-able ballast.

so i can get the ballast for $400, and the pump for $150 (both full retail, i know i can find them both for much cheaper, but we'll use these numbers). so that puts us at a cost of $550 for the "guts" of the rig. that leaves us with your round PVC, some tubing and some nozzles and a 20-gal res....oh and the price of putting it together. is it made in the USA? what parts are made in the USA?

speaking of a 20 gallon res, shouldn't there be a bigger one? not a dro expert either, but 50 plant sites and a 20 gallon res? just a thought.

i'm not trying to argue or say your product is crap, but i do like my purchases to be solidified in logic. you can also expect me to challenge anything posted on these forums. just the way that it is. thanks for the information.

finally, there are 10 holes in the top of each ring, couldn't you clean via those holes and not need the special connections?
