For this hydroponic system, channel lids ship without plant holes. Hole spacing and size varies depending on plants and size of plant medium.
Typical spacing for 1-3/8" holes is 8" on-center for most lettuce varieties as shown in this example.
1. Select one 8' channel lid and mark the center of the top at each end. Take a chalk line filled with
non-permanent
chalk, stretch it from end-to-
end, align with center marks, and snap a line.
2. Mark center of the first hole at 6" from one end. From that mark, mark the remaining hole positions at 8" on-center along the chalk line. There
will be twelve (12) hole positions when completed.
3. Place lid on scrap plywood (or similar material) for backing (if desired) and drill 1-3/8" holes using a drill and hole saw bit. (No backer is needed
if using a step bit.)
4. Repeat these steps to prepare and drill the remaining lids.
5. Rinse the lids to remove all shavings so these will not plug the nutrient circulation system. Set the lids aside for later.
6. Continue with the next procedure.
