Im building a couple 4x8 tables on casters that will have a 4x8 flood table on top of frame. So my question is would you put plywood over this frame? I will have 8 7gallon smart pots in each table. This will not be a table i fill with water just something to protect floor and so run off drains to waste. I dont think i need to put plywood on since 2x4's are 16 inch centers and a flood table will be on top. Am i good to go like this or am i setting my self up for problems not buying plywood?

Thanks! Thats what i figured but wanted to be sure before i mounted a permanent trellis on to frame. Good call on killz! I had to look it up but will probably paint that on. Its going to be a nice little design i think. Put the casters on so i can get in between tables

If it's not gonna be moving around alot it's fine,if you think you'll be moving it alot or putting it on casters/wheels I'd throw a sheet on it or at least a few gussets to add rigidity.

If you try to move that with weight aboard it will "rack" or turn into a parallelgram and possibly fall apart. Applying even a thin sheet of plywood (like the back of an Ikea dresser) ties everything together and eliminates that concern.

Get some plywood on there, even if 1/4 inch. Get low VOC paint, if in Cali only option. Good luck.

Some building advice looking at your table. The joists (cross pieces) have a crown or (bend) to them. The crown should always be facing up. It makes for a stronger table without sags.

Was thinking the same thing, but couldn't tell if it was an optical delusion. (optical illusion, but I always say delusion and people look at me funny)
