Hydroponic Root Pest Problem
by Paul
(San Diego)
I have noticed some mite like bugs on my DWC roots. The look dark to the naked eye, and under the 30x the appear to be green with redish dark behinds. The look like 4 legged, but may be 6. How can I kill them asap and not damage my roots? And what did I do to cause this? I have never had this problem before. Thanks for any help asap.
Answer: Paul- The most common hydroponic root problems by far are caused by fungus gnat larvae. However, your description pretty much eliminates this as the culprit, and I have not been able to find any garden pest that matches what you describe. I learned the hard way how important proper identification can be sometimes....you can read about my bug woes here.
That said, there are a couple things you can do. First of all, consider buying some good 35% Hydrogen Peroxide solution from a hydroponic shop. There are directions on the bottle for diluting the Hydrogen Peroxide for use in your nutrient reservoir (on living plants). Follow these directions very carefully. A proper dose could bring your bug problem in check very quickly, but a wrong dose can kill your entire crop just as quickly. Be sure to read my Using Hydrogen Peroxide page for all of the most important information.
The other thing you need to do is keep trying to properly identify the little pest. Sometimes the best way is to go to Google images and search for "garden pest", "hydroponic garden pest", "indoor garden pest", or other similar search terms. Including the word "roots" or "root pest" might get you somewhere. Compare the pictures carefully to what you remember seeing....this is exactly how I identified my thrip problem.
Once you identify the pest, the website hosing that particular image will often have information on how to get rid of it (or, at the very least, should be able to provide you the name of the pest, which you can then use to do additional research). Once you know the name of your foe, it is just a matter of time before you find the cure. I hope this helps Paul....I know how frustrating bug problems can be! Good luck, and Happy Growing!

AffordableGarden Design&Setup
Hi everyone, Jason from Jason's Indoor Guide here. When I got started with hydroponic gardening more than 24 years ago, my first garden used rockwool cubes and B.C. Nutrients....and I remember thinking to myself yeah, sure, there may be a lot of advantages to gardening with hydroponics, for example there are very few pest problems, therefore very little pest control, no weeding, no plowing or tilling the soil, no soil testing or having to add things into the garden soil, no watering the garden....but for someone who just wants to grow their own vegetables and have more control over their food supply and the quality of the food that they eat, the cost of constantly having to buy grow media and hydroponic nutrients makes this an expensive hobby for most people...
Epic Nutrient Change
I suppose when you take into consideration how much money you save NOT
having to buy food at the grocery store, it is surely cheaper to grow
your own food hydroponically even with the cost of high quality
nutrients. Nevertheless, I didn't have a whole lot of money to work with
and I needed to make my efforts as affordable and effective as
possible....and in the last 24 years I HAVE learned a thing or two!
As you browse through Jason's Indoor Guide, you will notice all of the
systems that I use personally are homemade systems. As I got 3 or 4
years of experience under my belt, I quickly adopted a preference to
standing water systems and systems that use expanded clay pellets or
lava rock, because the media is re-usable and it eliminates a huge
operating expense. So once a hydroponic system is built, garden
maintenance is minimal- check and adjust the nutrient solution daily,
and to change it completely every 2 weeks....and the biggest operating
cost is the hydroponic nutrients. (and the electric bill, lol)...
Homemade Cloner
And, regarding the cost of the nutrients....I experimented for about 3 years with making different compost teas and nutrient teas, but there is still a lot of expense $$$ associated with making high quality nutrient teas....like kelp meal, liquid seaweed, rock dust, bat guano, un-Sulfured molasses, worm castings. You can eliminate a lot of this expense by becoming an expert at making high-quality colloidal humus compost, and use your properly made compost as the basis of your hydroponic nutrient solution.
Unfortunately, I have been gardening for over 24 years and I have only
just recently mastered this difficult skill....and even then, only
because I happened to find a very easy to follow, high quality technique
and decided to follow the instructions to the letter. I produced more
high quality compost in just one week than I was able to use in a whole
year! If you can master the technique, I highly recommend it. It is one of the top 3 things you can do to
increase the productivity of your food production efforts, while at the
same time decreasing the amount of effort required to grow all of your
own food, and decreasing the total cost of operating your food
production system.
And when I say decrease operating costs, I mean decrease them to almost
ZERO, especially if you are producing your own nutrients...
High Efficiency
Hydroponics
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--->
Aquaponics
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.
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!
