Germinating seeds

[cannamaniac]

I've recently (14th Feb) sown 20 seeds each of the following. Fargesia albocerea black, Fargesia Papyrifera, Fargesia Yunnanensis, Chusquea Culeou and Phyllostachys Viridis Sulphurea. I soaked the seeds in tepid water for 24 hours and then sowed them into a 50/50 multipurpose ,sharp sand mix. Then covered each pot in a clean plastic bag then placed them in a heated propagator set at 25c.Two days ago (18th) I noticed 4 sprouts in the albocereas and 5 in the papyriferas .
My dilemma is this. Should I keep those pots ,with sprouts showing, covered to slow down evaporation to maintain ideal germinating conditions? Will leaving the bags on jeopardize the health of the new sprouts with too much humidity?

I usually keep them uncovered as soon as they poke out of the soil. Well, this time, as you've might have seen, I'm growing whole bunch of P. arcana 'Luteosulcata' seedlings and they grow super fast, without even misting them (their leaves, I do mist the soil when it gets dry so it takes water better).

You can leave it covered and open it for a couple of hours per day, just to make sure there's no mould explosion. Soon, they will get too large for the cover anyway. Good luck.

I'll uncover the pots with new sprouts for a few hours to let them air but I hope the drop in temperature wont slow the emergence of un-germinated seeds in those same pots.

I usually keep them around 22°C to 25°C. If it drops below 20°C, you might even see a difference, if not, I seriously doubt it.
