Ah yes I like the idea of doing a winter hydroponic garden. I have nothing against growing without soil, we have limited time with all our endeavors at the moment. We are moving into a small mobile home on raw land... between building something for winter, a garden and a couple natural building cottages for off-grid winter getaway rental income.
But I do want to try sooner than later, so perhaps your suggestion will motivate us for it!
Thanks
