Ferguson Zone & UVB
The Ferguson Zone system categorizes reptiles by their natural UVB exposure needs, guiding lighting choices.
Semi-aquatic species bask intermittently near water. Provide low-to-moderate UVB (5–6% T5) over the basking/dry area, with easy access to a clean water section.
Zone 1
Crepuscular / Shade
Zone 2
Occasional Basker
Zone 3
Open Sun Basker
Zone 4
Full Sun Lover
Temperature Gradient
basking surface
88–95°F (31–35°C)
warm ambient
78–85°F (26–29°C)
water
75–80°F (24–27°C)
Humidity
70–90%
Lighting & Photoperiod
5–6% T5 HO UVB over the basking area. Halogen basking bulb above the dry dock. Aquatic LED for the water section. 10–12 hr photoperiod.
Heating
Basking bulb over dry land area. Submersible aquarium heater for the water section. Water filtration is essential.
Decor & Furnishings
- •Large dry dock or ramp for basking
- •Submersible or canister water filter
- •Aquatic plants (Anubias, Java Fern, Duckweed)
- •Cork bark or stone land area
- •Driftwood for climbing and basking
Setup Notes
Water quality is critical — use a quality filter and perform regular water changes. Ensure the water is deep enough for full submersion but with an easy exit ramp. Basking area must be fully dry and warm.
