The Spider Farmer 4-Pack Gravity-Fed Self-Watering System is designed to keep your plants perfectly hydrated with almost zero effort. Using a 13-gallon gravity-fed reservoir and wick-based moisture control, this system delivers consistent, silent watering to each pot—no electricity, pumps, or daily checks required. It’s ideal for growers using 4×4 or 5×5 ft grow tents, as well as indoor gardens and greenhouses.
This all-in-one kit is perfect for busy growers, frequent travelers, or anyone who wants reliable, low-maintenance plant care while still achieving strong, healthy growth.
Effortless, Automatic Watering
-
Gravity-fed design continuously feeds water from the 13-gallon reservoir to each pot base.
-
Once filled, the system can keep plants watered for up to 2–3 weeks, supplying up to 4L of water per plant per week.
-
No power, timers, or pumps needed—just fill, set, and let your plants drink as they need.
Precise Moisture Control
-
Wick lines allow plants to absorb only the water they require, preventing overwatering and underwatering.
-
Encourages deep, healthy root systems and stable growth in all stages (best once roots are well developed).
Adjustable for Different Pot Sizes
-
Each fabric pot base includes three wick line positions, so you can easily adapt to:
-
1–2 gallon grow bags
-
3 gallon grow bags
-
5–7 gallon grow bags
-
-
Includes five 5-gallon grow bags, making it easy to start right away.
Silent, Clean, and Tent-Ready
-
Completely silent operation—no pump noise, perfect for indoor spaces.
-
Each base has a 15.6" diameter, optimized for 4×4 and 5×5 ft grow tents (recommended tent sizes: 120×120 cm / 150×150 cm).
-
Great for both soil and coco-based systems where consistent moisture is key.

Pro Tips for Best Results
-
Lay the bases, valve box, and tubes flat and keep the reservoir filled.
-
Clean the basins every two weeks to prevent root clogging.
-
Use once plants have well-developed roots—seedlings with shallow roots may not reach the moist zone effectively.
-
Customize moisture by changing the number of wicks: more wicks = more water.
