The WaterFarm 8-pack is eight WaterFarm module units connected to one General Hydroponics Controller: an integrated 13 gallon reservoir and an 8 gallon controller unit. The Controller will keep each unit topped off with the correct level of nutrient for low maintenance. The nutrient solution is circulated by GH's Dual Diaphragm Air Pump. Includes all the necessary hardware, supplies and General Hydroponics Flora Series nutrients. The grower can arrange the WaterFarm units in a design that is suitable for any environment. Pack them tight or space them out for your growing situation. The WaterFarm 8-Pack is the system for big growers. Can be expanded to a maximum of 12 grow sites for one controller.

We love the controller and reservoir that comes as part of this system. They make a huge difference once the plants get bigger and allow us to go on vacation without worrying about the plants running out of water or nutrient. By the by this is a hybrid NFT-deep culture system providing the benefits of both. If you have the clearance recommend raising the buckets and controller/resevoir off the floor the height of a 5 gallon bucket plus 3" to simplify draining the system at the end of a grow or whenever you might need to.
It's worth noting you can expand this system from 8 to 12 buckets. I' m sure this would work very well for smaller plants but would not recommend it for larger, nutrient hungry plants like Tomatoes without upgrading the nutrient circulation because the plants at the end of the line will likely receive water completely stripped of nutrient by the plants earlier in the line.We see a hint of this in both of our 8 bucket, air pump driven, circulating systems. A small electric pump replacement for the airlift fixes this but is only necessary when you have mature (4' plus high) tomatoes plants in all 8 buckets with lighting tailored to support maximum growth. We disconnect the air lift from the 1/2" tubing in the controller and add a $20-$30, 100-120 gallon per hour Eco+ pump and the problem is fixed in literally 5 mins.
Ours is located in the basement inside a grow tent. We use a small fan to keep air moving and have experienced no moisture or mold issues. We're based in the Great Lakes and have cold winters. Our biggest problem is lack of pollinators. We have to do it all by hand and use a combination of paint brush and stem shaking to achieve high pollination rates. This is by far the most labor intensive chore associated with using this hydroponics system. About 30 mins per day at the height of flowering. If that sounds like more work than you want to deal with I wouldn't recommend trying anything that relies on pollination to produce what you want and recommend you check out a flood table-lettuce raft system which will cost considerably less and produce amazing lettuces ready to eat in 5 to 6 weeks. A 2x4 foot raft system can meet the lettuce requirements for a family of 4. This can also be a great option if you love to cook with fresh herbs.
Would we buy another Waterfarm? Yes, without hesitation. Do we need to? No, one of these systems provides a lot of hydroponic growing space and I suspect would meet the needs of the average family of 4 looking to hydroponics to supplement their grocery purchases. Imagine 4 Tomatoe plants and 4 pepper or egg plants in a space 2'x16' or 4'x8' with no deer, yellow jacket, ant, racoon or rabbit damage. We have Tomatoes that are 7' high covered in perfect fruit. The kids pick them fresh off the vine at will. If this is what you're aiming for this s Waterfarm system can deliver it.
