Use 8 holes, spaced 250 mm apart, for plants that are left to spread and harvested whole, and 15, at 125 mm, for seedlings cut early. The key factor is the width a mature plant takes up: two butterhead lettuces at 125 mm will crowd each other well before harvest.

The summary

What it is: a 2 m channel through which a thin film of nutrient solution flows beneath the roots.
What sets it apart: the hole spacing is chosen at the time of ordering, 125 or 250 mm, with a factory-drilled lid.
Two densities: 8 holes spaced 250 mm apart, or 15 holes spaced 125 mm apart.
What you grow in it: lettuces, seedlings, and herbs with a small root ball.

2 m growing channel, 100 x 50 mm profile, 8 or 15 positions to choose from.

The 2 m NFT growing channel, 100 × 50 mm, lets a thin film of nutrient solution run beneath the roots. The hole spacing is chosen when you order: 8 holes at 250 mm centres for head lettuces, or 15 holes at 125 mm centres for baby leaves and herbs. This choice is final, as the lid is drilled at the factory.

This 2 m channel with a 100 x 50 mm profile is ordered with a lid pre-drilled at the factory at the spacing of your choice, 250 mm or 125 mm, and this choice then determines which crops it can carry. It arrives with its end caps glued on and a 5 cm basket for each position.

📏 8 holes or 15

At 250 mm centre to centre, the lid carries 8 positions over 2 m. Each plant has a quarter of a metre to spread out, which suits a head lettuce grown to full size, a batavia or a basil cut several times, since these crops need about twenty centimetres between plants. At 125 mm, the same channel carries 15, close together, and that is the density for baby leaves, lamb's lettuce, rocket and herbs harvested early.

250 mm spacing

The channel holds 8 positions over 2 m, for plants that spread out and are harvested whole.

125 mm spacing

The channel holds 15 positions over 2 m, for short cycles, harvested young.

5 cm pots

The holes take 5 cm diameter baskets, at both densities.

A choice that locks in

The lid comes pre-drilled from the factory: the spacing cannot be changed afterwards.

Germinate seedlings separately before filling the channel

A nutrient film channel takes plants that already have roots, not seeds. The peat germination pods take the seed in their central hole and slip whole into a 5 cm basket as soon as the roots show through, within 5 to 10 days. This spares you from uprooting the plant when transplanting, and each slot in the channel receives only a plant that has already sprouted.

🔩 The end caps and the run

This channel is the one fitted to nutrient film systems with a 100 x 50 mm profile, with 15 positions on the 60-plant system. Ordering it on its own serves two purposes: replacing a warped or cracked channel, and building a longer line than what a system supplies. Its end caps arrive factory-bonded, in one of the two configurations offered, so you have no end piece to seal yourself.

Choosing the end stops according to the position in the line

The channel comes with its end fittings bonded in the configuration you choose: drainage at both ends when you connect several channels end to end, drainage on one side and a blanking plug on the other when the channel terminates the run. Count your end points before confirming your basket, as a bonded fitting cannot be replaced.

💦 Water depth and slope

The profile is 100 mm wide by 50 mm high, with a 2.5 mm wall. This height limits the volume of water held at the bottom of the channel, and therefore the reserve available to a root if the pump stops: in a nutrient film system, that reserve is almost nil, whatever the length of the channel. The useful flow rate remains modest, in the region of 1 to 2 litres per minute per channel, just enough to maintain a continuous film without drowning the roots.

The usual guideline for slope is about 1 cm per metre, which means a 2 cm drop between the two ends of this channel. Set it on fairly closely spaced supports, because 2 m of channel loaded with mature plants will sag between two supports that are too far apart, and check that the water comes out at the end before installing a single plant. A line made up of several channels should stay under about twelve metres, because beyond that the plants at the end receive a solution that is already depleted.

🪴 Preparing for planting

A single channel can be planted up once it is connected to a reservoir, a pump and a return, then filled with rooted plants in the baskets supplied. The plants are prepared separately, about 3 weeks earlier, on an indoor seedling table. On a line extension, also allow for the support that will hold the slope, and repeat the check with clear water after each clean: a channel that has been laid crooked shows up at that point, before the plants are put in place.

If the water comes from a fish pond, mechanical filtration upstream is essential, because a 50 mm-high profile clogs quickly with suspended solids. The pH is then set first for the fish and the nitrifying bacteria, around neutral, and the plants in the channel benefit from the nitrogen the pond supplies in the form of nitrates. For longer-term crops, such as strawberries or herbs grown as bushes, the 80 mm-high channel offers more headroom under the lid.

Two channel profiles

The same principle and the same material. This table compares only the profile and slot density.

The profile is chosen based on the mature plant This channel is the lower of the two, which allows it to accommodate up to 15 plants over 2 m. The questionnaire looks first at the size your plant will reach once fully grown.
