Unfortunately, even in a controlled environment there can still be a problem with deficiencies. Fortunately, there are ways to overcome these deficiencies with the proper use of certain products. Below are a few things you can do to help prevent deficiencies. For more tips and ideas, please contact us and one of our knowledgeable staff members will be able to help you.
Nutrients, on the other hand, can get a little tricky, especially if you're trying to mimic the natural nutrient intake that a plant gets in a hydroponic system. Hydroponics vegetable gardening nutrients are amongst the hardest parts of a system to choose, because they need to be "optimized" for the particular plants that you're growing.
One of the best ways to prevent problems before they happen is to talk to knowledgeable people that understand hydroponics. We can explain all of the do's and don'ts before you start, thus giving your plants a better chance to succeed and prevent any unnecessary problems.
There are lots of things that can cause a hydroponic nutrient solution to drift outside of the ideal range of about 5.5 - 6.5. Usually, if a nutrient solution is left unmonitored for too long, it can start drifting outside of this range because of bacterial populations. Aerated water at good temperatures (71 degrees or below) will increase in aerobic bacteria, and pH goes up. Even though the pH needs to be adjusted, aerobic bacteria are good for plants. If water temperatures get too warm, anaerobic bacteria will cause pH to drop. Anaerobic bacteria are the microbes that cause root rot.
Since pH levels can change very rapidly, it is important to check your pH level daily. The longer your nutrient solution spends outside of this ideal range, the greater the chance that your flowers or vegetables will suffer a plant deficiency. Use a pharmaceutical grade pH adjustment product designed specifically for hydroponics to make the necessary adjustments.
Your nutrient solution should be fairly cool to temperate, somewhere in the range of sixty six to seventy one degrees Fahrenheit. You should be particularly aware of this if you happen to live in an unusually warm or cold part of the world. If you feel it is necessary to prevent plant deficiency, take extra steps to insulate your grow room against outside elements. You should also try placing your reservoir directly on the floor, as the floor can be very cool, which can keep the reservoir cool in a warm grow room.
The most common deficiencies can be cured by adding a Calcium Magnesium supplement and an organic micronutrient supplement such as seaweed extract.
There are several additional products that can increase the availability of nutrients for your plants. Beneficial Bacteria are extremely important to keep roots healthy and clean. Beneficial Fungus will increase root growth. Enzymes clear out any dead root cells. All three of those biological additives can assist in breaking down nutrients for easier uptake by the roots and ensure a large, healthy root zone. Large roots have an easier time absorbing nutrients.
Humic Acid, Fulvic Acid, and B Vitamins can all increase plant metabolism and/or nutrient uptake.
