Hey folks, I ordered some square black pots for my new batch of babies, turned up today and... they stink, or should i say they bloody reek! You know, that horrible black binbag plasticky smell - is there any way to remove it? I tried washing them with very hot water and some washing up liquid but that didnt help much. Or should I just go and buy some different ones? Thx for any input, want to repot tomorrow.
