Ask the Hydroponic Gardening Expert

jason willkomm, the resident hydroponic gardening expert here at Jason's Indoor Guide

Hello, and welcome to my hydroponic gardening name is Jason. I would like to thank you for visiting Jason's Indoor Guide. My very favorite hobby is my indoor garden. I have been at it for 20+ years now, and I have steadily gotten better and better results over time.

I can't tell you how many times I have been asked, and have repeated, some of the advice here to a friend or acquaintance eager to get started in the right direction. I have personally helped design, start, and kept running smoothly literally hundreds of indoor gardens over the last 20+ years!

Obviously, it was just a matter of time before I put a whole resource together that would teach people the basics, take them step by step through designing a garden, choosing appropriate equipment, and provide them with all of my recommendations. That resource is Jason's Indoor Guide.

I try my best to make all the information here simple, but also very helpful. Before you submit a question, please look through my Site Map and browse a few pages....the answers to many questions can be found here already. Even more answers can be found in my other FAQ pages. Yet, in spite of my best efforts to make all of the information here complete, there may be something I have overlooked....or perhaps something I did not fully explain. So....

Do You Have a Question?

Most simple questions come from visitors getting ready to start their first indoor garden. Once your garden is started, however, unanswered questions can become horrible, nagging problems that prevent you from getting the results you want! Believe me, I've been there! Drop me a line and tell me your experience can help you avoid or fix those problems.

High Efficiency

The ultimate solution to eliminate the cost of your hydroponic nutrients: Imagine a hydroponic system that does not require you to buy any nutrients, does not require you to make your own compost, and does not require you to brew your own nutrient tea. Seriously! No cost and no effort as far as providing nutrients to your plants! Plus, at the end of the gardening cycle you harvest all of your garden vegetables, PLUS YOU HARVEST FISH from the system....

This solution is aquaponics. If you are serious about producing all of your own food and being self-sufficient, this is the ultimate solution for reducing expenses (as much as possible), reducing the total amount of work required, and maximizing the productivity of your gardening efforts. I have been gardening for over 24 years, and it is the perfect food production solution in my opinion.

Produce garnden vegetables AND fish together. Eliminate fertilizer costs!

Besides mastering how to make high quality compost, learning aquaponics is one of the top 3 things you can do to increase your garden productivity, reduce your total costs, and reduce your total work. The product that I learned from is called Aquaponics4you. With all of my hydroponic gardening experience, the first time I came across the Aquaponics4you product I knew immediately that it was something very special! Place an aquaponics system outdoors and use the sun instead of grow lights, and you have reduced every garden expense to nearly ZERO!
