The Economy Cool Tube system comes complete with the 19 inch Cool Tube. Cool Tubes offer the most compact and effective way to get bright light over, or in, your growing area. Due to their streamlined design, cooling airflow can move unimpeded, keeping growing area temperatures lower and allowing you to position your lamp very close to your plants. These lamps are also excellent hanging vertically down into the plant canopy or for enclosed growth chambers. The tube measures 19 inch long and has a 6 inch diameter. The Xtrasun ballast is extremely efficient and reliable. It boasts a 5 year warranty, the best in it's class. The standard MH bulb comes with a 1 year warranty. We also include a 15 foot cord that connects the 14 inch socket cord to the ballast. General Hydroponics exclusive new control kit is included in the bundle pack. Our kit contains pH Up (add a little at a time when your nutrient pH is too low in order to raise the pH to the desired level), pH Down (uses food grade Phosphoric acid to lower the pH to the desired level), and pH Test Indicator (fill a test-tube halfway with nutrient, add a few drops of pH Test Indicator, and observe the coloration of the liquid in the test vial. Use 3 drops per 5mL of solution). Pipette also included for easy transfer of all liquids. Make sure to clean the pipette between uses. This is another great product available exclusively from Hydroponics Market.
