I have ordered the same cage that I have seen several people using online which I believe has a thin flat pvc material floor. Noticed that most people are drilling holes in the center to drain, using the weight of a plant on top to warp the floor and cause the water to gather in the center. Just woundered if anybody has had any structural damage (floor collapsing, etc). Any advice is be appreciated. Dont wanna come home and be suprised by a huge mess
