Greenhouse plants in summer need watering every 12-24 hours. A gravity-fed drip irrigation kit waters 10-20 pots for up to two weeks unattended. Capillary matting draws water from a reservoir tray and keeps compost evenly moist. DIY bottle drippers cost nothing and sustain a single pot for 3-5 days. Combining automatic roof vents with timed watering keeps a UK greenhouse productive through a fortnight's holiday.
