Problems with Root Rot?

Have you tried cloning your plants in an aero cloner and haven't had much luck? Is the stem slimy and the roots rotting? Most of the time the reason is because you have made a common mistake.

The first thing that you need to do is make sure your cloner is completely clean, down to the pump's spinner. If you have to reuse the neoprene collars make you they have been cleaned very very thoroughly. Try to use food grade cleaners but bleach can be used if you have nothing else. If bleach is used make sure all residues have been rinsed out. If you think you've rinsed it out enough, do it one more time. There could be a few reasons why you are getting root rot.

Water Temperature - Make sure your water temperature isn't too high. With summer time the water temps can get pretty high. Keep it around 70-75 and you should be good. Bacteria growth take off in higher temps.

pH - Your pH level needs to be between 5.5-5.8 for aeroponics. This isn't soil or hydro, a pH of 6 is getting too high. If you don't have a digital pH meter you might want to get one. Hanna makes a really good Digital Waterproof pH/EC/TDS Tester that runs about $150. Make sure you pH test after adding anything into the water.

Preparing your cloner - Some people do use a clearn or clone solution in their water but you don't necessarily have to. However, you can add 3% hydrogen peroxide (H2O2) to your water to help prevent nastiness. Add about 1 tablespoon (the measuring kind, not the one you eat with) of H2O2 per gallon of water.

Just follow these tips and you will be good to go!

      Hello goz,

      If you are consistently wanting to keep H2O2 active in the system you should add it every 3-5 days since the product does dissipate over time. If you use H2O2 on an as-needed basis, you would just add it when you notice your pH starting to swing. However, if you are using a small cloner like this Daisy Cloner pictured you may want to consistently use H2O2 in it.

      If you use H2O2, how often should you add more?
