Phenohunt for breeding project

Soaked seeds in water for 24 hours, then moved them to paper towel in a Tupperware container for 1-2 days until 1/2 inch tap root. They were then planted in 4 inch pots with reused and re-amended soil. After a week I transplanted 6 into 10 inch 3 gallon pots with pro mix. I had a couple seedlings showing signs of root rot but when I transplanted they had already corrected themselves and have plenty of very white roots. Problem was caused by my watered the seedlings probably a day or two earlier than I should have, not a huge deal. I am pheno hunting the BBM first to keep a mother and a father for breeding stock, as well as pheno hunting a mom and a dad of greenroom, which is a CBD strain, 12/14%. Planning on doing a seed run for blueberry and then making some crosses as well, with greenroom, as well as one of my own moms of a different cultivar.
