what can i use instead of plastic pots
I am potting on lots of seeds and I have run out of small 3inch flower pots. Does anyone have ideas what I can use - have thought of coleslaw pots etc but they are clear - does this matter or do the roots need to be in darkness. I really don't want to have to buy any plastic pots - when I think of the hundreds I must have thrown away over the years. Only got my greenhouse this year and have been going mad growing seeds. Any ideas would be appreciated.
