Thank you for the compliment. Gravity feeds are simple and don’t break down. You have a battery powered shut off for a gravity feed- I need several for my outside garden and haven’t found any. Please provide info If I understood you correctly. I believe growing outside is going to be very important for the majority of people who want to grow. I would love to start consulting in the Seattle area but it is totally illegal to have your own plants. I am no scofflaw but when it comes to growing my own, outside in my yard I do it and have been very happy with the results- so have my friends.
Take care my friend. I hope you beat the cancer and live many more productive, healthy and happy years.
