Res size suggestions

Hey folks, finishing up on aquiring all my materials for my first hydro grow. Anyone willing to suggest what size reservoir I should be using? I would like to only have to change out water/nutes every 5-7 days. I plan to grow 2 at most 3 plants. Most likely going to stick with 2 though.

Would 2-3 gal tank be enough, or should i look for something a little larger?

i use a 4 gallon res for two plants. you dont want a huge one because of the cost of nutrients so 4 gallon works well for me.

what size is your table ? That will determine what size reservoir you need .
