is this big enough

[cbgeckos14]

ok well theres a rack for sale and it holds 12.7qt tubs and i was wondering if that will be big enough to hold a adult leopard gecko. also im starting to breed and when my female ovulates what im going to do is put the male in there for a day and then take him out and put him back in a few days later will this tub be to small for them and should i just make my own rack system

It depends on the floor space/dimensions of the tubs. Those tubs could be taller making them hold more qts but taking away from the floor space.
I prefer to, and will always build my own rack. I can make it exactly how I want it. Like right now I am building a rack that will hold 63 baby tubs, 6 adult tubs and 12 breeding tubs. It will also have shelves down one side for storage of cleaning supplies etc. No rack builder will build something like that for you without charging an arm and a leg.
