Alright, lets get this journal going again! Its time to reverse sex on a DBHP clone for a feminized version using Sodium Thiosulphate Solution.

The chemicals

We’ll start with making the stock solutions starting with the Silver Nitrate stock


0.5grams gets dissolved into 500ml (2c) distilled water using a plastic spoon. It starts out as clear…the longer its exposed to light, the darker amber it gets.

Now for the sodium thiosulphate stock


This sodium thiosulphate is the pentahydrate (crystal) version rather than the anydrous (powder) so it takes ~0.67 times more than the powder to balance out the silver nitrate. This also gets dissolved into 500 ml (2c) distilled water

The mixed stock solutions

Next I pour each into its own dark bottle and kept in the fridge. So for the next year, I can refresh the working solution. The working solution is made by taking 10ml of Silver Nitrate stock and pouring it into 10ml Sodium Thiosulphate stock

I then dump this in a brown glass sprayer bottle and add 180ml distilled water for a bit further dilution

Now when I spray, I make sure the soil is covered so the chemicals don’t run off and affect the roots as the girl gets saturated not once but twice ~15-20 minutes apart out of direct light

After the 2nd spray down and mostly dried, the plant gets set under 12 hrs light to initiate flower

There is a lot of spray left. I could put it in the fridge with the stock solutions for the next 30 days though this 1:9 dilution is really only good for the 1st spray so down the toilet it goes and gets treated as a normal girl just starting to flower… in 5 days, she will receive another spray down of the mixed stock solution though with a stronger 1:4 dilution
