DRILL TUBE HOLES IN LIDS AND INSTALL LIDS
Channel Preparation: Lids
Complete these steps to drill holes for the nutrient tubes:
1. Take twelve (12) channel lids and arrange so all the plant holes and ends of the lids align. Take the
remaining channel lids and repeat this step. Keep the two piles separate.
ATTENTION:
For the first pile of lids, drill the nutrient tube holes where the first plant hole is closest to the
end of the lid. See A in the photo.
For the remaining lids, drill the nutrient tube holes where the first plant hole is farthest from the end of the lid.
See B in the photo.
2. Once the lids are separated, move to pile A and drill one (1) 5/16" hole in each lid where plant hole is closest
to the end. See the diagram that follows. Keep lids in the same group when completed.

Lids are designed with off-set holes for improved plant growth. During installation, alternate lids as
shown. Before snapping lids onto the channels, drill the nutrient tube holes at one end of each lid.

Holes
ATTENTION:
When sliding the lids onto the
channels, position the nutrient holes opposite
the drain end/elbow of the channel.
ATTENTION:
Drill holes away from open
channels to prevent debris from dropping
into the channels.
3. Move to pile B and drill one (1) 5/16" hole in each lid where plant hole is farthest from the end. See the
diagram that follows. Keep lids in the same group when completed.
