How to choose the right hydroponic grow equipment for your home?
Choose the right wattage for the appliances of your hydroponic system. Having higher wattage in tools like growing lights can severely stunt the plant’s growth. Moreover, devices like air pumps can have more additional watts that will not harm the plant but will increase your electricity bill at the end of the month.
How do I calculate the power consumption of a hydroponic system?
Multiply the watts of the device by the number of run hours for the device (some devices can use different power at varying times of the day). To calculate this, do the math for each wattage which matches the daily period and then add together. Do this for all the hydroponic devices you may want to use and any electrical devices you already have.
What wattage is best for grow lights?
As a rule of thumb, aim for 20 to 40 watts per square foot. Divide the wattage of your bulb by 20 (such as 400 watts divided by 20 = 20), and then divide the wattage of your bulb by 40 (400 divided by 40 = 10). The answer gives you the extremes of your light intensity range.

Is a remote ballast better than a flood ballast?
Remote ballasts are much better for home systems. This is the most expensive element of the lighting system, so it must be kept off the ground to ensure that it never gets wet in case of a flood or leak. Flooding is risky with systems such as Ebb & Flow in case your drainage tube gets clogged.
How to reduce the amount of light needed for plants?
You can also severely cut down on the amount of light (and electrcity) you need to use, by putting highly reflective material around the lights, so it bounces back on the plants.
What wavelength of light do plants need?
Plants mostly require light in wavelengths of around 430,450,650,675 nano meters ( depending on the crop), with highly varied intensity requirements from crop to crop. Lettuce requires mostly the high end of the blue spectrum of light, 650-700 nm, at an intensity of 17 mols/m2/day of PAR (Photosynthetically Active Radiation). If you do some research you may be able to find the manufacturers data sheets for certain lights, which may include this information, although you may have to contact the manufacturer for more in depth answers.
What temperature should I use for lettuce?
For flowering/fruiting plants, I would actually recommend using more than one color temperature (like a 2500k one and a 5000-7000k one, if not more than two). However, for lettuce, you probably want mostly the higher color temperatures which should help the leaves grow most.
