Each self watering reservoir can be used by itself or linked to other PlanterWell reservoirs to create a self irrigating window box or planter.

Not only do PlanterWell self watering reservoirs reduce the times that a planter needs to be watered it also improves plant growth and reduces water usage. Each PlanterWell will irrigate 9" of soil beyond it's edge, so one 24" planter well reservoir will keep the soil moist in a window box or planter that is 42" long.

Self-Watering Reservoir Instructions:

Step 1: Place a thin layer of gravel at the bottom of the planter. This will provide emergency drainage in case of over-watering.

Step 2: Place 1"-2" of soil over the gravel, and then place the self-watering reservoir on the soil base. For very large planters, connect multiple reservoirs with linking units.

Step 3: Insert the fill tube into the reservoir and trim so it is 1/2"-1" above the top of the planter.

Step 4: Fill the planter with soil to the desired level. Tamp it down but do not pack it firmly. See below for soil tips.

Step 5: Add plants as usual. You can hide the fill tube if desired, but make sure you can easily pour water into it.

Step 6: Water the soil thoroughly and add water to the fill tube until the reservoir is full.

Step 7: As time passes, add water to the fill tube as necessary. Usually, it will take the plants 1-2 weeks to use all the water in the reservoir.

Step 8: Enjoy your plants as they grow healthy and strong without worry of over- or under-watering!

Hooks & Lattice recommends a lightweight, fibrous soil for use with self-watering reservoirs. This will assist the "capillary action" that draws water to the roots and help the distribution of moisture throughout the root zone. Avoid soil with too much sand or clay. Soil less potting mixtures with perlite, peat moss, and coco coir work well.

Frequently Asked Questions about Plant Reservoirs | FAQ

Question: How do I use my planter reservoir?

Answer: As suggested in Step 7 above, you will need to monitor your self watering reservoirs once you've initially installed them. Typically, you will not need to add water to your window box reservoirs for approximately two weeks. However, this can fluctuate due to time of year, weather and temperature, and plant variety.

Question: How do self watering pots work?

Answer: Self watering pots have a straightforward design based on physics. There is a plastic hollow platform that sits in the planters or hanging baskets underside. This creates the reservoir. The topside of this platform always has at least one and usually multiple holes that allow water to drain from watered soil and collect beneath the platform for later use. The fill tube is attached to and is part of this mechanism. When the plant roots need water, they draw it up through the soil through capillary action, or wicking. This further hydrates the grow medium or soil for the plant roots to "drink" from.

Question: How much water do planters with water reservoirs hold?

Answer: Since water reservoirs for planters are designed and sized to fit the container they will be used in, the amount of water each reservoir holds varies. In general, capacities range from 1.25 gallons up to 7 gallons of water. If you have a large planter that requires watering window boxes greater than reservoir sizes we carry, we recommend you purchase more than one reservoir to install in your planter. Please check size and capacity for each reservoir we sell above and purchase according to window box size and reservoir lengths and widths. In no time, you will eliminate frequent watering by using your DIY self watering planter. Another alternative to using multiple reservoirs in overlarge planters or boxes is to purchase a custom self-watering system.
