Volume boost for your grow box

Beyond a certain tent size, our small Spaceboosters may no longer be sufficient to effectively tension the tent walls outwards and prevent them from contracting due to negative pressure.

Also ideal for attaching ready-made SCROG nets.

For larger grow boxes, we therefore recommend this option.
The brackets are designed for additional horizontal poles and are constructed to actively push the tent walls outwards. This creates noticeably more space inside the grow box.

Please note that approximately 5 cm of clearance is required on the sides around the grow box so that the holders can function optimally.

Background & Idea

Due to the negative pressure created by the exhaust air, the tent always immediately contracted inwards.
The tent walls were in the way, took up space and significantly hampered work in the grow tent, reducing the usable area, especially in the area of ​​the canopy.

Especially with more powerful exhaust systems, this quickly became a persistent problem.
So a solution was needed that would reliably stretch the tent walls outwards, increase the available space and make the overall setup more relaxed.

Additional bars

You have the choice between inexpensive, somewhat less stable PVC pipes or very stable yet inexpensive aluminum pipes .

Both versions are available with a diameter of Ø 16 mm .

The additional rods are always required with a diameter of 16 mm.

The tent dimensions vary to fit your grow box.

For shipping and storage reasons, we currently do not offer suitable poles.

However, M16 installation pipe is available in every hardware store or online – starting from approximately €0.41 per meter.

The cheapest supplier of aluminum tubes we have found is Stahlshop24 Alu 16mm at a price of approximately €2.42 per meter.

Universal use

The brackets can be used not only to stabilize the tent walls, but also to build your own SCROG net or to attach a finished SCROG net neatly and stably.

Extra space in your grow box

The holders are firmly and securely attached.

In combination with the additional poles, the tent wall is effectively pushed outwards, creating noticeably more space inside the grow box.

Frequently asked questions about the holders

Currently, no.

For shipping and storage reasons, we currently do not offer suitable poles.

You will need rods with a diameter of 16 mm, which are readily available, for example as M16 installation pipes, in any hardware store or online.

The additional rods always require a diameter of Ø 16 mm.

The length depends on the size of your grow box and can be individually adjusted.

Approximately 5 cm of free space is needed on the sides around the grow box.

This space is required so that the holders with the additional poles can effectively stretch the tent walls outwards and fully perform their function.
