It looks like you started from seed. They look nice and healthy! You gotta love it when you are able to get a sorority house up and running. Are you doing a pheno hunt or do you know what you have going there? I was the sales manager in the commercial division of one of the largest hydro shops in the country for the last 3 years. Helping individuals and facilities in every aspect of their growop. What an interesting 3 years. Good luck with your adventure. Looking forward to your progress.
