Double or Nothing: A Grower’s Life Lights Lights are the heart of your garden and the key to your plants’ growth—if your lights go out you’ve got to get them back up and running as soon as possible. If you are running HID or fluorescent lights like most indoor gardeners, the lamp or the ballast can fail. The best option is to keep spare grow bulbs and ballasts on hand, but that can be expensive. A second, less ideal option is to keep some shop lights (four foot T12 fluorescents) around—you can hang these inexpensive fixtures in place of your broken grow light while you go to the local hydro store for some troubleshooting. Shop lights will maintain your garden’s day/night cycle temporarily, although your plants will stretch and grow poorly under these weak lamps, so make sure you get your real grow lights working again as soon as possible. Pumps In my hydro systems I always use two pumps: one large pump to run the system and a smaller pump that sits in the reservoir and stirs the solution. Since I incorporate some organic supplements in my nutrient solutions, dirty or clogged pumps are inevitable. Pumps are one of the only products that have decreased in price at hydroponics stores. Fifteen years ago, I would pay $60 for a pump for an ebb and flow system, but these days it’s more like $25. Admittedly, higher-quality pumps can be purchased for a higher price tag and they might offer a better warranty—for a spare pump, though, the lower-cost option is acceptable. Air stones If you use air stones, you know that they eventually clog and stop bubbling. I have seen the same growers replace their air stones again and again over the years I’ve worked in hydro stores. Let me save you a few bucks. There is an easy way to use the same air stones for years without replacement. First, you will need to buy the heavy air stones, not the thin brittle ones. Second, you will need two air stones for every one that sits in your reservoir. Each time you change the nutrients in your reservoir, remove the wet air stone and replace it with a spare. Clean the used stone with a scrub brush and let it dry out completely—drying reduces clogging from microbes and algae. The newly cleaned 60 Maximum Yield USA | March 2012
