“Considering hot house, organic, hydroponic tomatoes growing in Northern California. Need a lot more knowledge of subject.”

Hi Jerry! I am jealous – I’ve been wanting a greenhouse of my own.

Organic tomatoes would be a natural addition, and hydroponics is fascinating.

For general organic hothouse tomato production information, head on over to the National Sustainable Agriculture Service. This website is courtesy of the National Center for Appropriate Technology, which is funded by the United States Department of Agriculture’s Rural Business-Cooperative Service.

They aim to educate commercial growers and educators about sustainable agriculture. There’s a wealth of information to help you grow your tomatoes.

Northern California is a good location for growing tomatoes. What zone are you in? Are you intending to grow tomatoes for sale? As their article points out, “Greenhouse tomatoes bring the highest price from December through April, when it is too cool for local field-grown tomatoes. Winter growers may choose between a one- or two-crop system”

The fertilizer you use is very important if you want these to be organic. Appendix 2 of that article has a great set of recommendations for organic fertilizing methods. For example, Magna Gro has a Hydroponic Base Mix (HBM).

For specific information on growing tomatoes using hydroponic methods, visit Arizona University’s tomato site.

These two sites should get you well on your way to producing a bounty of hydroponically-grown organic tomatoes. I wish you much luck in this endeavour if you do decide to try it.
