Best options for reversal

Here’s a thread I created a while back that links to Sebrings recipe and Tony Greens notes.

Silver Thiosulfate - Making feminized seeds

Hey now! I’m brand spanking new when it comes to making feminized seeds. Had a few questions and thought this bunch might be the right crew to help out. I’m using Silver Thiosulfate to reverse a GDP. I’m about 4-weeks into flowering and the first three weeks, every week, once a week I’ve applied the thiosulfate right after lights out. Question 1: Metal and Silver Thiosulfate. I don’t know if I’d screwed up because I’d heard somewhere that one should never use metal when working with STS. …

STS and two applications will do what you need.
