On both sides 1ft under the rectangle holes I drilled another set of holes (big enough for just the probe etc) this is so the probe will re-enter the cabinet under the grow shelf in line with the PVC trunking, I drilled a further 2 holes in the forward facing trunking strips heading towards the RES. tubs.. to hide the probe wires before they enter enter the actual REZ. tubs in which they'll be set up to work within
Once in place, I covered the wire and holes with silver tape to A) keep smells and light in! and B) to keep everything neat, also if a battery change is needed I only have to pierce the top silver tape, change the battery from behind the scenes and replace the tape .......with more tape, happy days - STELTHY
