# Wilt & Water > Published reservoir capacities, computed refill intervals and honest limits for self-watering planters, vacation watering rigs, watering globes and spikes, and soil moisture meters. Written for people who keep killing houseplants. Site: https://wiltandwater.com Contact: info@wiltandwater.com Publisher: Slate Mill Group Author: Scooter M. (enthusiast; no horticultural credential claimed) ## What this site does Wilt & Water answers one question numerically: how long can you leave a plant before it needs water again? The answer is the reservoir capacity of a watering device divided by the volume of one thorough watering for that pot size, multiplied by the watering-frequency band published by Virginia Cooperative Extension (tropical houseplants: once or twice a week; succulents and cacti: once or twice a month). We do NOT test products. There is no lab and no test bench, and every page says so. Every specification carries the publisher it came from; where a manufacturer does not publish a figure, the page says "not published" rather than estimating one. Every computed interval shows its arithmetic and names its assumption. ## Funding model Affiliate commission.

Prices render only from a live data layer with a capture date; where no live price is held, the page says "Check price on Amazon" rather than showing a stale number. ## Sections ### Self-Watering Planters -
