Lighting control at your fingertips! The Master controller EL1 and EL2 Gen 2 are our entry-level systems for centrally controlling large rooms with e-series fixtures. The second generation of Master controllers features improved and expanded functionality that raises the bar including non-volatile memory, event logging, independent sunrise and sunset settings and independent light cycles on the EL2. The EL1 has one lighting control channel and the EL2 has two lighting control channels. The EL1 can control 500 max repeater bus fixtures and 40 max single bus fixtures without a booster. The EL2 can control 1000 max repeater bus fixtures and 80 max single bus fixtures without a booster.
The Gavita EL1 Master Controller can switch, dim or boost control 40 ballasts from a central point.
Using a Gavita Master controller to control your e-series fixtures offers you maximum control, ease of use, plug and play installation and safety. Just connect the controller cables to the fixtures with the included T-splitter (see diagram), set the dials on the fixtures to EXT (External control), plug the controller and the fixtures directly into mains and you are set to go.
The controller can switch all the interconnected fixtures on and off with its internal timer, adjust them to your required output level (in percentage or exact output power) and even simulate sunrise and sunset to gradually adjust the climate in your grow room when your lights go on or off. This electronic controller replaces expensive lighting timers and contactors while preventing ballast current in-rush when switching on your lights.
Two very important features are the autodim function and emergency shut-down. When the temperature in your grow room rises beyond the control level of your climate control your crop can be damaged beyond recovery. The temperature probe senses this and will automatically dim the lights to not overshoot your safe temperature, and maintain it. The display and warning LED indicate when this happens, and also indicate if this has happened while you were away so you can correct the problem. If for any reason your climate control completely fails and the temperature rises to unacceptable levels the system will perform an emergency shutdown of all connected equipment. The alarm contact of the controller can be connected to your alarm system for instant notification. You can connect all your e-series fixtures to one controller.

INFORMATION QUESTIONS
FREQUENTLY ASKED QUESTIONS
What is Hydroponics?
Hydroponics is the science of growing plants without soil. The plants thrive on the nutrient-water solution alone. The growing medium merely acts as a support for the plants and their root systems while the solution passes freely. The growing medium, if any, is totally inert.
What types of plants grow best hydroponically?
Anything can be grown hydroponically, but some plants prove to be more space efficient. Some plants we suggest are tomatoes, sweet peppers, hot chilies, lettuce, spinach, squash, cucumbers, broccoli, beans, snow peas, herbs and flowers of all types.
Can you REALLY get better yields/quicker growth?
Absolutely. The plants, when receiving everything they need, tend to be healthier, faster growing and generally more productive. You can expect 30% faster growth with many crops.
What are the watering cycle timelines hydroponic systems?
Once the reservoir is filled with nutrients, it is time to put your hydro system to work! The ease of hydroponics is automation – automation is achieved by putting the pump on a timer according to your watering needs. The watering cycle depends on growth stage, growing medium and hydroponic system. In an ebb and flow or drip system with rockwool as the medium, seedlings, clones and plants in the early vegetative stage require watering only once a day for 15-30 minutes (twice a day for higher temps). Mature, flowering and fruiting plants require a heavier feed and can be fed once a day for 30 minutes (twice a day for higher temps). Typically soiless mixes and coco fiber can be watered for about 15 minutes twice a day, and can be adjusted for heavier feeding during the flowering and fruiting stage or higher temps. ViaStone, Hydroton, Grow Rocks, and Silicate mediums need to be watered more frequently – a constant drip for drip systems, and about 15-30 minutes every 3 hours for ebb and flow systems and can be adjusted for heavier feeding during the flowering and fruiting stage or higher temps. Aeroponic systems require frequent watering cycles; 30-60 seconds every few minutes or a constant spray.
What do I need to test pH? How do I test pH?
pH has a range from 0 (acidic) – 14 (alkaline), with 7 being neutral. A proper hydroponic pH range is between 5.5 to 6.2 for most hydroponic crops. For specific crop pH, check out our Plant Guide. pH must remain within the proper range for good plant health, disease resistance, and proper nutrient uptake. pH is maintained by adding pH Up and pH Down to the nutrient solution. For more information, see the Testssection of our site.
How will the flavor compare to my outdoor grown, organic produce?
The taste may be even better! This is simply due to the fact that the hydroponically grown plants are getting everything they need, when they need it. Don’t be fooled by “hot house” produce grown commercially. The grower’s primary concern is shipability and storage, not flavor. When you grow your own vegetables at home, you can expect nothing less than excellent results. Plus, hydroponically grown produce has the added benefit of a longer shelf life.
