Hi @hartsuff1,
The LED lights in my counter-top unit only use 35w. When all my hydroponic systems, including my big garage system, are at full capacity - the total addition to our electrical bill for all the pumps/lights is around $22/m. I will have a post about that system later, when that one is not in use, it's around $10/m for all the others.
We save on average between $125 and $250 per month based on the type/volume of food our gardens produce - compared to if we had to buy the same items at the store. When everything of at peak, we usually have more than we can eat and give the extra to family and friends.
Thank you, I've built a small Aquaponics system in the past. It's so much better to grow your own. :)
