Â
Hi to Chuck Chapman,
I am using an old formula used by John Holden many years
ago, a simple phosphate buffered mixture with mostly calcium nitrate
plus some iron, magnesium, manganese, ammonium and potassium, 2%
sucrose, 0.6% agar. The reference is Aril Society International
Yearbook 1962, p 32. If you would like a copy of the formula I can
send it. Despite the antiquity of the formula it works really well.
Best wishes,
Peter Gras
