    We are going to be selling seed sowing supplies again this season, including 3" pots (tall for alpines), labels and GA3. Fitting the pots snugly into our old trays was problematic. Arie has come up with an excellent solution, so once again trays will be for sale. Watch the meeting pages in Dec-March for prices and availability.
