Anywhere! 3" is the same as 9cm. I got 10 for £1 at Poundstretcher the other day! I also make use of yogurt pots.

3" is an 8 cm diamter. I would have thought they would be available in most Garden Centres (I am assuming you mean plastic ones), but if you are having difficulty obtaining there are mail order sources. I recently bought plants from Dibleys.com and they also supply 8 cm pots, but with postage fee of course.

Actually 3" is 7.6 mm to be precise. I've just converted checking with ruler for you.

Jonathan my daughter has just done the somes to. Sid was nearly right! lol I agree with sid go to either the 99p shop or poundstretcher. I got 50 coir pots in 99p shop last week
