FAQs
Is the GardenTank difficult to set up?
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.
Can I use this reservoir with any hydroponic system?
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.
How does the Mylar lid help my plants?
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.
Is the material safe for my plants?
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.
What size pump is recommended for this reservoir?
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.
