I have a 12 bucket Ebb n Grow set up. I am thinking of changing over to a Sea of Green cycle. Should I stick with the Ebb n Grow, and expand using 36 more buckets, or should I change over to a completly new Hydro set-up?

It will cost me about:

$60 bucks per 6 buckets.... $60x6=360
$50 for clay pellets per 6 buckets.... $50x6=300
$50 for each res. I will need three more..$50x3=150
Total:$810.00

Seems like it would be a sweet set up once it is all going, But seems abit spendy...Of course this is retail and I could try and buy buckets and convert them for the hardwear store...Any Suggestions out there?
