Help using Relays with greenhouse

Sorry, my mistake.

void loop()
{
  // current time;
  unsigned long currentTime = millis();
  // start time of read delay
  static unsigned long startTime = 0;

  // humidity, tempC, tempF
  float h, t, f;

  // if delay not started, start delay and read dht
  if (startTime == 0)
  {
    // set the start time
    startTime = currentTime;

    // read dht
    h = dht.readHumidity();
    t = dht.readTemperature();
    f = dht.readTemperature(true);

    if (isnan(h) || isnan(t) || isnan(f))
    {
      Serial.println("Failed to read from DHT sensor!");
      return;
    }
  }
  // if delay lapsed
  else if(currentTime - startTime > 5000)
  {
    // reset start time
    startTime = 0;
  }
