1. How do I mix the media for the HYDRO-STACKER™ vertical growing unit?
We use an equal mix of Perlite and vermiculite. We have the vermiculite specially formulated for our units. The Perlite is the largest size we can have made. The better the quality of the media mix, the better the plants will grow.
2. How much room do I need to grow in the HYDRO-STACKER™ unit?
It takes 14 square inches to grow in the HYDRO-STACKER™ unit. Sunlight is needed for the plants to mature and flourish. Be sure to give the plants at least 5 hours of sunlight each day.

1. Can you plant different plants in the HYDRO-STACKER vertical garden at the same time?
Yes, it is best to plant the most aggressive plants in the lower planters. Tomatoes, peppers are some aggressive plants. Lettuce, carrots, radishes, collards, beans are less aggressive. By aggressive we mean the thickness of the root system.
2. Is Secret Sauce organic?
Our Secret Sauce is a blend of natural ingredients. Secret Sauce is not organic certified. Presently there are no standards for hydroponic organic certification.
3. How do I mix the Secret Sauce?
The Secret Sauce is packaged in an easy to use plastic bag. Simply pour the entire contents of the package marked “A” into a gallon of fresh water. Well water, city water, will work fine. Shake the gallon till all of the mix is liquid. Now take the package marked “B” and pour it into a separate gallon container of water and shake it well. Make sure to keep these two containers marked and do not pour them together, except when making the nutrient for feeding. Take a ¾ tablespoon of “A” and ¾ tablespoon of “B” and put them into a third gallon of clear water. Shake well and now you have your nutrient ready to use. Pour one quart into the diffuser of the unit for each feeding. For good plant growth you should feed three times daily. The amount of Secret Sauce that comes with each unit should last for one growing season. Be sure to reorder before you use it all. Do not use Miracle Grow in your unit. It is made for soil growing and will not work well in your Vertical Growing Unit.
4. Do I change the feeding times when the temperature reaches about 90 degress?
This depends on what you are growing. The plants will tell you if they are not receiving enough nutrients. If they look droopy or are not growing, it is probably time to give them some help and feed them a little more. Do not over feed your plants. Too much nutrient only harms the plant.
5. What should the pH of the water be for the best growing in the HYDRO-STACKER™ System?
To achieve maximum plant growth, a level of 5.6 to 6.2 is best. To get good results, a grower should purchase a pH meter. Out of all the things to buy, a pH meter is the most important. This tool will become an important factor to your plants growth.

1. Do I need to take my HYDRO-STACKER system inside during the winter?
Yes. Like any growing equipment, good care should be taken. Clean the outsides of your unit and place in a nice dry area. You can remove the plants or let them dry some and then, pull them out. Reuse the media each year. Make sure there is not a lot of root growth left in the unit when you store it. Decaying roots leave a very bad odor behind.
2. Can I add the electric kit to my HYDRO-STACKER manual feed system?
Yes, it is very easy to convert any manual units to our convenient auto feed system. The auto feed system will handle up to fourteen stacks at one time. No other unit on the market can achieve this.
3. Can I get updated and/or replacement parts for the HYDRO-STACKER™ System?
Yes, we are working very hard to make our unit a customer friendly and easy unit to grow in. All of the parts are available for replacement.
4. Can you reuse the media in the hydroponic system?
Yes, just make sure you remove as much as the old root system as you can. We have people who have reused their media for five years.
