seed treatment

http://www.growseed.org/seedtreatments.html


For general use, seeds are soaked in 2.7% sodium hypochlorite (half-strength standard household bleach) for 30 min. (60 min. for S. cheesmaniae, S. galapagense, S. ochranthum, and S. juglandifolium). After bleaching, seed should be rinsed thoroughly, then sown directly (i.e. without allowing to dry) in germination boxes or in soil.

you can speed up the sprouting process and protect your seedlings from mildews and molds with simple hydrogen peroxide.

For wet sprouting (when using a flat surface and wet paper towel or other cloth) simply spray the outer surface of the damp material enclosing the seeds with a 3 percent hydrogen peroxide solution once a day after remoistening the sprouting seeds.

If you're using seed starter peat pots or other soil-based sprouting media, add 1/4 volume of 3 percent hydrogen peroxide to the water before watering the sprouts.

Using hydrogen peroxide in the watering and sprouting material will eliminate fuzzy molds and bacteria which often attack sprouting seeds. It will also speed up the sprouting process sometimes by as much as half.

There are many disinfectants that can be used Sodium hypochlorite (1-5%) or 10% Calcium hypochlorite. mercuric chloride 1% is also
useful.

Mixing charts for gardening with hydrogen peroxide

If you want to start gardening with hydrogen peroxide, you need to know how much peroxide to use. Here are charts to tell you how much!

To water or mist plants, to soak seeds, to add to water used to wash sprouts:

TO THIS AMOUNT OF WATERADD THIS AMOUNT OF 3% HYDROGEN PEROXIDE--OR-- ADD THIS AMOUNT OF 35% HYDROGEN PEROXIDE
1 cup1 and 1/2 teaspoons7 to 10 drops
1 quart2 tablespoons1/2 teaspoon
1 gallon1/2 cup2 teaspoons
5 gallons2 and 1/2 cups3 tablespoons plus 1 teaspoon
10 gallons5 cups6 tablespoons plus 2 teaspoons
20 gallons10 cups3/4 cup plus 1 tablespoon plus 1 teaspoon
bathtub (aprox 25 to 35 gallons) *12 to 17 cups1 to 1.5 cups
* bathtub sizes vary. It is okay to use more water and/or less peroxide.

To spray on sick or fungusy plants:

TO THIS AMOUNT OF WATERADD THIS AMOUNT OF 3% HYDROGEN PEROXIDE--OR-- ADD THIS AMOUNT OF 35% HYDROGEN PEROXIDE
1 cup1 tablespoon1/4 teaspoon
1 pint2 tablespoons1/2 teaspoon
1 quart1/4 cup1 teaspoon
1 gallon1 cup1 tablespoon plus 1 teaspoon
5 gallons5 cups6 tablespoons plus 2 teaspoons
10 gallons10 cups3/4 cup plus 1 tablespoons plus 1 teaspoons
20 gallons20 cups1 and 1/2 cups plus 2 tablespoons plus 2 teaspoons
Please be mindful to choose the correct column in the chart depending on whether you are using 3% hydrogen peroxide or 35% hydrogen peroxide!!
