I've used Jiffy 7 peat cubes. WalMart sells a plastic tray with a clear cover holding 72 cubes.
I have 12 healthy plants, two years old, with 5 to 9 culms 3/8"-5/8" dia., in a greenhouse. They are dark green so far. A few of the seedlings are small with only I hope you will keep the forum posted on your results; germination percentage, etc.

Did you give them light? What temperature did you use?
I will keep you informed.

The cubes were kept in an open tray on the kitchen table, indirect light and room temperature.

If I have really got Bambusa lako, I know have 4 seedlings after less than a week at about 85 F on top of a sand + cocofibre soil in high humidity and low light. What should they be potted on into?

Many thanks
