First, I always pop my bean in ro water in a solo cup. Then I fill the cup with foxfarms ocean forest with about 1/2 inch from top. Then when I have a tap root, I stick my finger in the soil about an inch down drop the bean in tap root down and cover the top. I lightly water, not very much first time as soil is fairly moist. Then I wait for the sprout to enter the world. After that I wait for the soil to dry out a bit then feed it good. I only ever transplant once. When she is ready and outgrowing the solo cup I fill a 3gal pot with the soil and use another solo cup as a slrt of place holder when I am filling with soil. Once soil is in and packed lightly (don’t over pack as the soil needs airation), I take out the empty solo cup (place holder cup) from the soil in the 3 gal pot and take my plant in other solo cup, tip it upside down squeeze lightly and out she comes. I then place her in the hole where the empty cup was for a pretty perfect fit ohhhhh, forgot something…before putting plant in the hole empty solo cup was in I always sprinkle root magic around the area where the empty solo cup was and where I will now put my plant. Root magic is awesome and always helps my roots acclimate to their new environment. I don’t like to transplant more than once. I know a guy who starts his bean right away in a 5gal bucket. Hope that answers your questions. Any more feel free to ask.
