Sizing a Self-Watering Base to Your Pots
Self-watering bases solve two problems: missed watering during travel, and over-watering during recovery weeks after stress events. The
AC Infinity bases use a wicking-mat reservoir that draws water up into the rootzone on demand, so the pot stays at consistent moisture without daily attention. Pot size drives the base choice.

| 10-15 gallon |
XL 4-Pack |
~4 gallons per base |
How Wicking Affects Watering Frequency
Bottom-feed wicking changes the rhythm of a grow. Instead of manual top-feeding every 1-2 days, you fill the reservoir every 5-7 days during veg and every 3-5 days during late flower. The plant pulls only what it needs, which keeps the rootzone at consistent moisture instead of cycling wet-to-dry. The trade-off: bottom-feed only works well with media that wicks (coco coir, peat-based blends). For pure perlite or hydroton, the wicking action is too weak to lift water far enough. Use coco or coco-perlite mixes for best results with self-watering bases.

Frequently Asked Questions
How long between refills?
5-7 days during veg, 3-5 days during late flower for the Standard base. The XL base extends both intervals by 2-3 days thanks to the larger reservoir. Actual frequency depends on plant size, ambient temperature, and tent humidity. Check the float indicator daily until you learn the rhythm.
Does the base fit any fabric pot?
It fits any flat-bottom fabric pot in the matching gallon range. Standard fits 5-7 gallon pots from any brand; XL fits 10-15 gallon. Pots with handles or unusual shaping at the base may not seat flat. For best wicking contact, use pots with a flat bottom that sits directly on the wicking mat.
Will the wick handle 15-gallon pots?
Yes, with the XL base. The XL wicking mat is sized for the higher water demand of large plants in 10-15 gallon containers. Standard bases are undersized for 15-gallon pots and will run dry under heavy water demand in late flower. Match the base size to the pot.
Standard vs XL, which one?
Standard pairs with 5-7 gallon pots, which is the common home grow size. XL is for 10-15 gallon pots, which is the size for very large single-plant grows or commercial-scale plants. Match base size to pot size. Don't run a 15-gallon pot on a Standard base; you'll be refilling daily.
Does the base cause root rot?
No, the wicking-mat design only delivers water when the rootzone demands it. The pot bottom never sits in standing water; the mat acts as a one-way capillary feed. Root rot risk is actually lower with self-watering bases than with manual top-feeding because the rootzone moisture stays consistent instead of cycling wet-to-dry.
Can I run nutrients through the reservoir?
Yes, fill the reservoir with the same nutrient solution you'd use for top-feeding. Mix at 50-75 percent of normal strength because the plant draws water more consistently than with manual feeds, which can cause salt buildup at higher concentrations. Flush the reservoir with plain water every 2-3 refills to prevent salt accumulation in the wicking mat.
