What Goes On in the Greenhouse at 5 AM

Five a.m. in the greenhouse is chaos disguised as quiet. The automated vents are opening. The irrigation system is running. Seedlings are waking up.

This is the hour that decides whether you'll have healthy plants or sickly ones. Most people don't see it.

Temperature Check

First thing: read the night's low. In spring, a single night of 35 degrees can kill tender seedlings. The wall thermometer tells us what happened while we slept.

If it dropped too low, we check for damage. Wilting. Black leaf edges. We move sensitive trays up higher in the greenhouse where it's warmer.

The Watering Walk

Drip lines can clog. Nozzles can drip when they shouldn't. So we walk every bench, checking that water is reaching each plant. Not too wet (causes root rot) and not too dry (stunts growth and invites pests).

Scout for Problems

Spider mites. Powdery mildew. Algae on the soil surface. Insects. We look for early signs when they're easiest to stop. A few mites today = a full infestation in two weeks if you miss it.

The greenhouse at 5 a.m. is when you see things clearly. No noise. No distractions. Just you and the plants.
