4" GH pot holders...
 

Usually greenhouses have their plastic pots in holders as to not let them topple over. I'm looking for theses 'holders' so I can have them in my GH when it is complete. Does anyone have a link to where I can find them or even what the proper name is for them. Thanks!!!

i found mine on E bay , also plastic trays for my 2" pots, i think i payed .25 each from a green house ,it was their surplus not used, good luck
