I started these tulsi specimen from seeds. The germination was no problem, but after the two cotyledons developed, growth has been slow to non-existent. Compare them to the horse chestnut seedling in the second pic - it was a germinating seed not long ago and has vastly outpaced the tulsi under the same light conditions.
I spray them fairly ogten with water and a light dose of nutrient supplement. The ambient temperature is moderately high (about 73F). I keep the flourescent light on around 10-12 hours a day. That stuff in the substrate is vermiculite.
Any advice for getting my tulsi to grow?
