I've essentially just grown my plants like I would in potting soil. I've just been giving them filtered water with a low dosage of hydroponic fertiliser. Plus a bit of root stimulant every now and then:
The small plants are tomatoes, big ones are hydroponic green beans. The tomato pots with vermiculite are hydroponic and the ones without are potting/seed raising mix. The bigger tomatoes in the top left were started earlier than the rest.
Zucchinis. They really grow quick!
The plan has always been to use the Kratky method. I don't see these big plants trying to grow roots out the bottom on their own, I'm assuming I need to coax them by setting them up in the reservoir right about now.
