what paint to use?

hey i wanna repaint my cupboard and last time i used undercoat (primer)
but i cant remeber if it should be oil or water based ? can someone plz help!

Well odds are most primers are water based. So there, it was prolly water based primer. :)

you can have oil or water based primers.. obviously if you use a water based primer and then try to use a oil based paint, you'll have a problem. ... personally for a grow box, i'd always use water based anything.. those fumes from oil based paint can be pretty bad sometimes.. especially if it's a close cupboard
