STS reversal spray

Blockhead Buds Silver Thiosulfate Solution (STS) spray 16 fl oz. is specifically formulated to create feminized seeds for home and commercial growers.

INSTRUCTIONS

This comes as a 2 part solution, part A and part B.  Take stock solution “B” and gently pour it in the spray bottle.  Add stock solution “A” to the “B” and swirl it around, then quickly add distilled water (not supplied) to your mixed solution.  Add enough of the distilled water to fill up the spray bottle to the top of the neck, leaving a small space for surfactant if you want to add.

Directions for use:

During lights off spray STS liberally onto the plant you’re looking to reverse a few days prior to flipping to 12/12 (flower).   Spray at the nodes where flowers/buds form vs the leaves and spray enough for the solution to saturate the nodes.  Spray plant daily for the first 2-3 weeks until you see pollen sacks appear.  Sacks usually start to form around week 3-4.  For optimal timing of pollinating your receivers, I like to quarantine the plant that I’m reversing and I flip my receiver plants around 1-2 weeks after I’ve flipped my donor (plant I’m reversing).

Depending on your needs, spray a whole plant or just one branch.

Dilute Solution if your plants show signs of burning. Some strains/phenotypes of cannabis are more sensitive than others. A slight reaction is acceptable, while severe reactions require diluting with additional distilled water. Simply open the spray bottle and top it off with distilled water.

STORAGE

Silver Thiosulfate Solution is light and temperature-sensitive.  Store in your refrigerator or a cool, dark place.
