The BETA-8 CO2 controller offers a precision CO2 NDIR sensor/controller in an affordable easy-to-use package. The BETA-8 features a high-quality remote CO2 sensor (with 16ft cable) and built-in photocell to automatically activate your supplemental CO2 system to maintain CO2 PPM levels only during daylight hours. The BETA-8 also has adjustable deadband and min-max recall. It also has a ‘fuzzy-logic’ feature which will more accurately control compressed CO2 systems. The CO2 sensor can be easily re-calibrated and will continue to operate accurately for many years.

The BETA-2 can control variable-speed fans by using the current temperature to increase or decrease the fan speed. By increasing the fan speed, cooling is increased… decreasing fan speed will reduce cooling capacity. Using the BETA-2 in this way provides a VERY economical and efficient way of dealing with heat within an enclosed space.

The BETA-6 features a precision humidity sensor within a 16ft remote probe assembly. Simply plug in your humidity/dehumidify device to the power outlet on the bottom of the BETA-6. The user can select separate “day / night” humidity settings and the photocell built into the BETA-6 will automatically start controlling your device (Settings from 20-90% rH). Either humidifiers or dehumidifiers can be controlled by the BETA-6.

The BETA-1 is a simple solution for the Mini Split Air Conditioners.

It uses the remote control that came with your mini split air-conditioner to “learn” how to change the setpoints on the mini-split. Just about any brand of mini-split unit can be controlled by the BETA-1. Once the BETA-1 learns the signals from your remote controller, it will automatically change the setpoint on the mini-split to two separate Day and Night temperatures. It does this AUTOMATICALLY by using a small IR (infrared) emitter/sending unit that will send the same signal to the mini-split, as the remote control would normally send.

The BETA-4 is capable of controlling any heating or cooling device that is 10-amps or less. Simply plug in your device to the power outlet on the bottom of the BETA-4.  It uses 3-buttons a digital display and offers separate "day / night” temperature settings and features a built-in photocell.

An excellent soil conditioner, alfalfa meal is a rich source of trace elements and natural growth stimulants. Recommended for all flowering shrubs and especially roses, alfalfa meal accelerates growth and promotes larger, more plentiful blooms. It is also useful as a compost bio-activator due to its high organic matter content and ideal carbon-to-nitrogen ratio.

A rich, organic fertilizer mix infused with a generous amount of beneficial bacteria and mycorrhizal fungi to stimulate rooting, vigor and optimum plant development. Bio-Live encourages rapid colonization of soil and soilless mixes and may be combined with other Down To Earth™ fertilizers to further improve plant growth and yields.
