Hi there! I'm wondering if you can help me with a bit of a dilemma. I have a small collection of tin cans just begging to have something done with them. I would love to use them to grow herbs in, but I'm a little worried they might be a bit small. I have three sizes: 300ml, 270ml and 250ml. Do you think they might be ok to grow something in them? Any help will be much appreciated. :)

oh, hi there!  not sure when you sent this so a million apologies if its been too long. 

i would say those sizes are good for starting seeds but overall they are too small to have anything growing in there effectively.  it wouldn’t be able to retain enough water i feel.  i would go with a tin at least the size of those standard ones used for coffee.  hope this helps!
