Terra Aquatica GrowStream 40 V2

Product detailed description

GrowStream 40 is large and fragile - it cannot be sent by standard courier. We dispatch it only for collection in store or by pallet transport.

Aeroponic yield without air pumps and controllers

GrowStream 40 is the middle unit in the range - forty growing sites on a 211 cm-long channel (dimensions 211 x 97 x 58 cm) with a shared tank of approximately 170 litres. The technology is based on the proven AeroFlo system. The roots grow freely in the chamber without substrate.

You harvest more from a smaller footprint and do not have to monitor any complicated technology. The system is powered by a single water pump in the tank, which periodically pushes the solution into the growing channel. The solution then flows back down the sloped base into the tank and is naturally oxygenated on the way, so separate air pumps and controllers are not needed. The roots grow freely in the chamber without substrate and have constant access to nutrients and oxygen.

Construction designed against leaks

You will appreciate the peace of mind during operation and cleaning. The growing channel has a removable lid for easy access inside and a double wall at the channel and the lid. The irrigation tube is routed inside the chamber, so no liquid leaks occur.

What you will need additionally

Add washed expanded clay to the system as root support (you will find it in the expanded clay / hydroton category) and fill it with nutrient solution. Plants are best placed into the system already rooted from a cutting tray or propagation area.

Which GrowStream size to choose

Across the GrowStream range, the mechanics remain the same; the channel length and number of growing sites change. Choose the size according to how many plants you want to grow and how much space you have:

• GrowStream 10 - 10 sites, compact separate tank of approximately 45 l, for a balcony or a smaller tent.
• GrowStream 20 - 20 sites, shared tank of approximately 170 l, shorter channel for a smaller grow room.
• GrowStream 40 (this system) - 40 sites, 211 cm channel, for a medium grow room.
• GrowStream 60 - 60 sites, 311 cm channel, for a large setup.
• GrowStream 80 - 80 sites, 411 cm channel, for a commercial grow room.

The 20 to 80 models share a tank of approximately 170 litres, so as the setup grows, mainly the channel length increases. You will find the whole range and accessories in the GrowStream / AeroFlo category.

Frequently asked questions

How many plants is the GrowStream 40 suitable for?

GrowStream 40 has forty growing sites on a 211 cm-long channel, so it is designed for forty plants in one unit. It is suitable for a medium to larger grow room. If you need fewer sites, choose the 10 or 20 version; for large and commercial setups, there are the 60 and 80 models.

Do I need an air pump for GrowStream?

No, no additional air pump is needed. Oxygenation is handled by the circulation itself: the water pump brings the solution into the channel and it is aerated on the way back along the sloped base. This saves you money on air pumps and control controllers. For operation, you only need to add expanded clay and nutrient solution.
