Rick, hi I have seen all your hydroponic You-Tube videos and now I want to try too.
What food plants, apart from tomatoes would you recommend? I am looking for survival food to grow, and can't just live on tomatoes.

different plants in the same system
by: old ed

Rick, great comments. I am now officially an old fart and am looking for ways to augment my pitiful retirement income. I saw an episode of "Life Below Zero" where they used hydroponics for their garden and a lightbulb went off. I decided then and there that I have hoed weeds in my last dirt garden.

Your comments regarding water and nutrition requirements for different plants in the same system were very interesting. Where can I get more information regarding which plants have similar requirements and can share the same system.

Thanks for your input.

What to Grow in Hydroponics
by: John

I agree that it's best to grow specific crops in individual systems. I'd go for nutritious greens, such as Swiss chard or kale.

RE: Hydroponics for survival

Hi Peter,
Thanks for your comment, glad you are looking in to building a hydroponics system, it's a lot of fun to work with.

Which plants to grow is a tricky question, one that I'm still trying to figure out for myself.
I guess it all depends on how much over-all hydroponic growing area you have. A hydroponics system like mine could never provide enough food to survive on, but it can supplement your other food supplies, or provide additional variety such as herbs etc.

I think the biggest lesson I learned this year with hydroponics is that the more different types of plants you grow in a single hydroponics system, the more difficult it becomes to grow them successfully, because each plant type requires different growing conditions.

For example growing tomatoes with lettuce was a bad idea. The tomatoes were heavy feeders and needed a lot of food, while the lettuce were struggling to cope with all the food in the water.

So my advice right now would be to choose one type of plant per hydroponic system.

As for plant types, Tomatoes and lettuce and other leafy greens are most popular as they are straight-forward to grow, and great for beginners.

I've also heard cucumbers and squashes do well grown in hydroponics, but I've not tried that myself.

Over-all I think the golden rule for any survival food garden is to grow only what you know you will eat.

I appreciate this didn't fully answer your question, but I hope it helped in some way.

Good luck with your hydroponics system, and do be sure to send us in a picture or a video if you make one :o)
