Thanks all for the responses
I have treated with a fungiside and they havent wilted over night.
Have to say i know how they got contaminated
who knew they shouldnt be opened oh well we all learn the hard way.
I have bought several books and read up about growing from seedlings but it is always the obvious that they dont print, not one said DONT OPEN the flask.
perhaps the fact germinating seeds needs to be sterile should have given me a clue.
The humidty generally is about 50% but i have put them in mini propagators with lids so hopefully that will help.
they are on a medium of bark and perlite with some moss to try and keep the humidity up.
Wish me luck not the best of starts
