Proteus,
Where are you planning to get your glosso from?
Can i make a suggestion? give Boronia Aquarium a go in getting your glossostigma. I got mine from them and the quality was great. Not stringly little sprouts like ones at my LFS but a fully packed stone wood pot with glosso growing out and around it. They are great health and started spreading in a week.
They can really do a great deal for you too. I got 50 pots from them at $4 a pot. And express delivery cost me $20
You bought that much glosso Try talking to the guys on one of the planted forums they give rare plants away for free most of the time. They know a fair bit too,
Matt
