Leopard gecko instructions confuse carers who expect a basking lamp, because this species takes its warmth from the ground at dusk, not from bright overhead light. Your written brief therefore starts with the thermostat and the warm hide, treats lighting as a simple matter of keeping days and nights distinct, and gives the carer one daily number to check so a silent equipment failure is caught within hours, not at the end of your trip.
Lead with the warm hide and its controller
Write the target where the carer cannot miss it: the floor inside the warm hide should sit in the high 80s to low 90s Fahrenheit, provided by the heat mat or similar under-enclosure source that is already fitted. Show them the thermostat box, its probe position, and the thermometer they should read, and explain that the probe must not be moved, buried differently, or taped elsewhere 'to tidy it,' because the whole system regulates from that one spot. Add the absolute rule in plain language: the heat source is never to be plugged directly into the wall without the thermostat in between, even briefly while rearranging plugs, since uncontrolled mats can climb far past the safe range.
Explain the cool end and the choice it gives him
Tell the carer the cool end should rest in the mid 70s, with its own hide, so your gecko can shuttle and choose. A carer who sees him spending the day in the cool hide has not found a fault; leopard geckos sleep where they feel secure and do much of their warming in the evening. What does deserve a message to you is the whole enclosure reading high, a warm hide that has gone cold to the thermometer check, or a gecko pressed flat and restless at the coolest corner on a hot day. In a heatwave the instruction is shade, ventilation of the room, and a call to you — never ice, cold water baths, or moving him into an air-conditioned blast.
Keep lighting dim, timed, and unimportant-looking
State that he needs no bright basking light and no special lamp for his health in the way a day-active desert lizard does. Ordinary room light marking day from night is sufficient, with any low enclosure light you do use kept on its existing timer. Ask the carer to do feeding and checks in the evening under normal room light rather than shining a torch into hides at midday, and never to leave a bright light on overnight to observe him. If a red or coloured night bulb is part of your existing setup, label it clearly; if it is not, the carer should not add one bought on a whim, because his night should simply be dark and undisturbed.
Include the humid hide as a heating-adjacent job
The one moisture task tied to this routine is keeping the humid hide's lining damp — not soaked — so he can loosen skin cleanly when a shed arrives. Tell the carer how you dampen it, where the spare lining material is, and that pale, dull colour across his body means a shed is near and handling should pause. After a shed, a quick look at the toes for retained rings of skin is part of the evening check; stuck skin that persists, or toes that look swollen or dark at the tip, is a call to you and, if you direct it, your reptile vet, rather than something for the carer to pick at.
Give one daily check and one failure plan
Ask for the same small ritual each evening: read the warm-hide thermometer, glance at the thermostat display, top up water, then feed on the scheduled nights. If the warm end reads cold and the thermostat shows no power, the carer checks the plug and calls you the same evening; a single cool night is not a crisis for a healthy adult, but several nights without belly warmth will stop him eating and digesting. KinsLe's Care Pass puts the thermostat setting, the daily check, and that failure plan into one temporary handoff at the enclosure.
