We have bought quite a few seeds over the last year, previously purchased in 2020. These recent autos seeds (4 auto strains) have had a significant fail rate,whereas original purchase in 2020 was very successful,they were feminized seeds. The recent seeds have either not popped or died once seedlings are about 10 cms tall. No changes to environment, grow indoors in tent. We have given some to other experienced growers and they have only had 40% success rate. Disappointing considering the money we have spent on both seeds and running costs. 20% success rate roughly for the autos we have purchased. Feminized seeds were higher success rate, especially in the seeds bought in 2020. We would like to purchase more but we are very wary about purchasing more autos.
