I had two plants growing in front of a glass door. Just getting about 6-8 hrs of sun. But I was using egg shell fertilizer. And they were growing so fast, I had to move them because they could be seen from the st. I was on the 2nd floor and abput 30 feet from the street. I know they were'nt getting enough light. So do you think it might have been the egg shell fertilizer? To make it. After you crack open your eggs for breakfast,just put the shells in a large jar of water. I guess I had about 8 eggs worth or more. Just enough water to cover the shells.I had a large pickle jar. And just let them sit for a week or so. You don't have to break the shells up.
