You will def need the larger reservoir. The tomato plant by itself will drink that reservoir empty in in less than 4 days when it matures, then add the cucumber and and you will be filling it every other day. It would be nice if Rise developed a 15-20gal reservoir because even their 9gallon is not enough if you're growing leafy greens and especially cucumber! Congrats on the great deal you got on that.
ya, right now it summer so just using them to start off plants or clones and am transplanting outside / for winter will get a bigger Reservoir for sure... thanks for feedback
