Who This Is For
- You are upgrading to a professional reservoir because flimsy plastic tubs often leak or warp under heavy water weight.
- You are scaling up your batch size because smaller tanks require too many manual refills throughout the work week.
What We Found
- The Mylar lid seals tighter than most generic covers, which is why it keeps the solution temp so stable.
- We find the aluminum frame is much sturdier than plastic poles that often bow when the tank is at full capacity.
What Users Say
- Users who grow in greenhouses say the UV-resistant skin prevents the membrane from getting brittle in the sun.
- Gardeners who do frequent water changes say the bottom drain tap saves them from manually siphoning every week.

FAQs
Not at all. The GardenTank features a simple, collapsible design with an aluminum frame that is easy to assemble and disassemble without any special tools. It's also convenient to store when not in use.
Yes, the GardenTank is designed for universal compatibility. It's an excellent standalone reservoir for custom builds or as a high-quality replacement for existing systems. It integrates perfectly with complete Alien Hydroponics setups, including their popular RDWC systems.
The heat-reflective Mylar lid plays a crucial role in maintaining a stable temperature for your nutrient solution. By reflecting external heat, it prevents the water from warming up, which helps maintain optimal oxygen levels and protects plant roots from heat stress and harmful pathogens.
Absolutely. The GardenTank is constructed from high-quality, plant-safe materials. The reinforced PVC membrane is durable and inert, ensuring that no harmful chemicals will leach into your nutrient solution and affect your plants' health.
The ideal pump size depends on your specific system (e.g., number of pots, tubing length). For a 70-gallon reservoir, a robust pump is recommended to ensure adequate circulation. The Alien Hydroponics V-System Vortex 250W Water Pump is a great starting point for many compatible systems.
