Yes! Thank you for that suggestion. I have seen several videos on Growing Power. Good stuff!
Hi Vorguen,
I don't know if aquaponics is more or less expensive. It probably depends on what you are planing to grow, and how much of it. And whether or not you plan to eat the fish. It's kinda cool to raise the fish for consumption and all the while the fish byproduct is helping to grow the salad at the same time!

If you don't want to eat the fish, a koi pond would be cool too.
As far as efficiency is concerned, It probably takes a greater time commitment to get an aquaponics system up and running compared to a hydroponic system. And the added "nail biting" involved with the caring for fish simultaneously may add up. Plus you can probably squeeze more yield out of hydro because you can just add whatever nutrient is deficient or would add benefit. In aquaponics you don't usually add nutes. Though, a naturally balanced aquapon system can produce very well too. If a natural grow cycle is most important then aquaponics is worth a look.
Along with the Will Allen's Growing Power videos on youtube there are tons of aquaponic videos. Some are geared more towards the "nuts and bolts" of how it works that could probably show you what it's all about better then I could explain it here.
But I'm still interested in continuing the conversation. What kind of plants are you interested in growing?
