PH is the measurement of Acidity or Alkalinity in a solution. PH is measured on a scale of 1-14 with 7 being neutral. Solutions measuring lower than 7 are Acids and solutions measuring about 7 are considered Alkalis (bases).  The ideal PH Balance varies with the plant that you are growing, however, for most applications 5.8 to 6.2 would be ideal.

PPM is best defined as “Parts Per Million” and is used to measure the concentration of solubles in your nutrient solution or how much CO2 is in your atmosphere.

EC or “Electrical Conductivity” is a unit of measure the Electrical Conductivity of a solution. An EC meter applies an electrical voltage to the solution and reads the conductivity that is produced from the motion of mineral Ions.




Indoor growing professionals often switch between bulbs for different stages of growth for a couple of reasons. Sodium bulbs have been known to make some plants grow leggy and stretched out because of the yellow to red spectrum that they give off, whereas,  Metal Halides often tend to keep these plants tighter with less space between internodes. Do not be fooled though, you can use either light throughout the life of a plant and get excellent results.

There are a wide variety of boosters and fertilizers designed to give your plants just what they need when they need it to produce abundant, vigorous blossoms and better harvests.that will increase flower size. Most common are bloom boosters that are concentrated in powder form and are high in phosphorus.

When going to purchase a light, the first thing you need to do is figure out the square footage you are working with. Depending on the type of plant will determine the wattage you will need. Most commonly with high-light plants such as  tomatoes, you will want to achieve around 40 watts per square foot for optimal growth and fruit production. And for low light plants, and small leafy plants like herbs and lettuce, you will only need to achieve about 25 to 30 watts per square foot.



No. Changing the Bulbs between systems should never be done unless the system is specifically designed to do so. By changing the bulbs, the bulb could become unstable and explode. Most ballasts are only meant to run the type of bulb they are rated for and are the general guidelines for best safety practices.

For obtaining the  best results, we recommend emptying your reservoir and replacing your nutrient solution with a quality fertilizer every 10 days. It is the only way to ensure nutrient levels are consistently in the ideal range for plant growth.
