Things are looking great! Have you ever consider multipot grows? I've found it a fantastic way to see many phenos at once and to see the fittest of the fit survive till the end, I started a 2 gal air pot with 40 beans in it, when all was said and done I had 10ladies at the end and gave me a great opportunity to try the different phenos and to get a better idea what I wanted to focus on for the f2's.... Also the 1liter airpots and 32oz foam cups can grows beast of the plants and you can get several in one small tent:... Just some ideas for us closet breeders, as regardless of the size of your operation selection is key! And trying to grow out as many of those beans as you can to learn the traits and which ones are dom or rec as also hetro in homogenous
Got a couple great breeding books I can share with you if interested...
Also give STS a look into, it's my daisy and my choice reversal agent, granted very very toxic compared to the healthy CS, but with proper protection it's a thousands times easier one to three sprays in a two week period or so and you'll have a fully reversed plant... No fuss involved! You can source the silver nitrate and the sodium thiosulfate from ebay from cheap, just be sure to buy each compound from a different person so not raise any flags.... Don't give up on finding that pink pheno if it's in it's genetic makeup it will eventually appear again.... Just might take a few or a few gens and back crosses...
Btw if you don't mind divulging what is the genetic make up of this cross?
