It's great to see somebody gearing up for the 2017 gardening season! That looks like a nice, tidy little system for a few plants, without taking up much space. Will you be starting your grapes and pomegranate from seed to put outdoors later? Or will you be growing them as plant starts? It will be interesting to see your tomato plants grow. With good light, they should stay short and get stocky, especially if you brush them around to encourage a strong stem, like if they were in the breeze outdoors. Happy gardening!
The pomegranates apparently only get to three feet tall, and the grapes are supposed to be compact plants also. I am going to see how they do permanently in the system. I'll probably have to start them in soil, and then transplant into the hydroponic though. They tend to mold too quickly.
This would be a great way to start plants for the spring and summer. I'd like to have one set up just for that if possible.
That would be something, to see grapes and pomegranates in a permanent hydroponic setup! Good luck with that, for sure! I look forward to seeing more from your system!
