Product Details
Maintain the ideal root zone temperature for seedlings, cuttings, and hydroponic plants with the CULTIV8 Thermostat Controller 🌱🌡️ Designed for use with heat mats and heat bars, this digital temperature controller helps create stable growing conditions for faster propagation and healthier plant development.
Heating plays an important role in hydroponic growing, especially during colder months or in cool climates. When temperatures drop below 18°C, plants can struggle to absorb hydroponic nutrients efficiently. The CULTIV8 Thermostat Controller helps maintain consistent warmth around the root zone to support healthy nutrient uptake and vigorous growth.
Simple to set up and easy to operate, this controller gives growers reliable temperature management for propagation systems and indoor gardens.
Consistent root zone temperatures are essential for healthy plant growth, particularly in hydroponic systems and propagation environments. Cooler temperatures can slow nutrient absorption, delay seed germination, and reduce rooting success in cuttings. By maintaining stable warmth around the roots, the CULTIV8 Thermostat Controller helps support stronger growth and healthier plants year-round.

"Peace of mind."
"Used with the mat to provide a constant fixed programmable temp to keep your reservoir nice and warm."
"So good to know whats going on with the root zone temp. I run it into heat bar ( from A Grade ) instead of a heat mat as plants are in 5 gallon fabric pots. I haven't needed to turn heat bar down this cold winter but a great option."
"Jason & Jasmine are Very helpful & have great products & Incredible customer service"
"Great addition to my setup, regulates my tents. Keeps my plants happy."
"Recommend using this especially if your seed trays are in a sunny spot in the window"
