Don't give them full sun until they're at least 3-4 inches tall, and then
only a couple hours a day to harden the stems. Then transplant
the seedlings into the ground or 4-5 gallon planters.
When (and they will) they start turning yellow give them nitrogen,
potash and miracle grow. Tobacco needs lots of Nitrogen. Here's how I use it,
Two parts Nitrate of Soda,
Three parts Phosphate of lime,
One part Potash.
This is a perfect fertilizer mixture for Tobacco and give them a sprinkle
at least once a week and adjust as they turn yellow.

I have one of those jiffy greenhouse deals.
Maybe I’ll try again.
And don’t PLANT in Miracle Grow! That time release stuff can really screw you if you have to flush your containers to rid the root system of too much sodium or you have nutrient lock out.
Do you have a formula for bamboo fertilizer?
