The Roots have to be large and complex to ensure that you get enough nutrients to your plant. Using a good root booster will allow maximum uptake of nutrients, and help your plant stay healthy and alive if there is ever a problem in the system.

If your PH balance is off, your plants will be too. Below 5.8 or above 6.3 and you will start to see bad things happening. Adjust the solution with a small amount of PH up, or down. If you use too much of one or the other then it will be harmful to your plants, and you won’t be able to correct it immediately.

Obviously if your temperature is too high or too low you won’t get very good growth. Most however don’t realize how much little changes in temperature can alter the plants growth. Between sixty six, and seventy one degrees Fahrenheit is ideal. Keep a thermometer in the nutrient reservoir and check at the hottest, and coldest times of the day to make sure that itis within this range.

This one sounds simple, but is commonly overlooked. Nutrient density is very important to plant growth. If the density isn’t high enough then the plants won’t get all they need, too high and certain nutrients will block the absorption of others such as iron. Using an EC meter you can check how much are in the solution. the higher the electrical conductivity (EC) the more nutrients are present.

Growing many varieties of plants from wild Japanese spinach to merlot lettuce and bronze fennel, even a variety of mint that tastes like mint chocolate. With more than 50 types of plants the brothers pull in about 200 pounds of produce per day.

They are strong believers in hydroponics, their gardens use less water, less land, and no pesticides, and because they are grown closer to market, less fuel to reach their final destination.
Currently they are getting good results in the dry desert climate with ebb and flow in their current green houses, with the third to be used for a new water culture system, and the fourth to be dedicated to aeroponics, where plant roots are misted with nutrients.

Around the world hydroponics has taken off – Australia, Israel, and the Netherlands being the leaders, while the US is lagging behind. “farmers tend to keep on doing what they’ve been doing for generations,” Tom Blount said.

The major reasons for this time constraint is the biology of the plant leaf and the desire to not burn the plant by wetting it during peak sun exposure resulting in leaf burn.

            A leaf will use its stomata to regulate the process of gas exchange, mainly CO2 and transpiration. Stomata holes are located mostly on the underside of the leaf and the location where the uptake of the feed is going to take place, also where some insects like spider mites suck their meal.

They open and close throughout the day however most transpiring will happen during peak light hours. Intake will be maximized just before night cycle, or when daylight breaks causing a new daily cycle of photosynthesis.

New products have come to market giving gardeners the ability to manipulate these stomata so that they remain open when the nutrient(s) are present. They are added to the foliar feed and they appear to work quite well. Adding a wetting agent, also called penetrating agent, with your regular foliar spray will increase yield and quality.

DO NOT ADD insecticides to these enhancers because you will be in effect feeding them poison, even if mentioned on the bottle. Neem oil, or your own organic recipe should be tested on a small section of the garden before applying to the whole crop.
