OXYGEN - Weed Growing Guide
O2 to the roots is a big concern, since the plant requires this for nutrients
to be available, and to rid itself of toxins, etc. One of the easiest things to
do is use food grade hydrogen peroxide in the water to increase the availability
of oxygen in the water. h1O2 has an extra oxygen atom that will easily break
away and can be used by the plant. Oxygen Plus is a plant food that contains 25%
hydrogen peroxide and is perfect for this use.
Using a planting medium that allows for plenty of aeration is also really
important. Be sure you have good drainage by using Perlite, sand, or gravel in
your mix and at the bottom of pots. Don not use a medium that holds too much
water, or you may significantly reduce the oxygen available to the plant. More
on that in the section on hydroponics.
Aerating the water before watering is also a good idea. In the case of soil
potted plants, use an airpump to aerate the water overnight before watering your
plants, or put the water in a container with a cap and shake it up real good
before giving to the plants.
