🏆 NFT grow channel 100 x 80 mm double wall : the premium profile for demanding crops
This Growrilla NFT channel is the high-end version of the 100 x 80 mm profile. The co-moulded double wall delivers two technical benefits : the thermal insulation of the nutrient solution (which heats up and cools down far more slowly than in a single-wall channel), and the rigidity of the channel over its 1.8 metre length, which carries a row loaded with mature plants without sagging.
The 8 cm height allows a more developed root system than the standard 100 x 50. It is the option of choice for growing more demanding plants in NFT, such as cherry tomatoes, compact peppers, everbearing strawberries in intensive production or highly branched herbs.

🌱 When to choose the 100 x 80 over the 100 x 50
The 100 x 80 is mainly worthwhile in three cases :
- Growing in a non-air-conditioned room with fluctuating temperatures : the double wall dampens the swings.
- Plants with a dense root system or high yields (cherry tomatoes, productive strawberries) where the 50 mm channel becomes root-bound.
- Long or suspended installations where the rigidity of the double wall prevents sagging between supports.
For classic lettuce in an air-conditioned indoor space, the standard 100 x 50 remains perfectly sufficient and more economical.
📦 Pack sizes and logistics
The single unit is for replacement or a small trial. The pack of 8 is the natural unit for a complete 4-level NFT module. The pack of 16 equips a complete pro module or a vertical green wall. Optimised logistics for large packs, with reinforced packaging.
💡 Pro tips : making the most of the double wall
Take advantage of the thermal stability to grow all year round in an unheated greenhouse : the nutrient solution stays in the optimal 18-22 °C range for longer, protecting the roots from thermal shock during cold nights or hot afternoons.
If you combine 100 x 50 + 100 x 80 in the same installation : place the 100 x 80 on the rows most exposed to sun or cold, and keep the 100 x 50 in the temperate zones. The cost saving remains significant.
