High Power Hydroponic Grow Light

Hydroponics grow box fluorescents
The importance of a fluorescent light in a hydroponics grow box
When most people are looking to purchase a hydroponics grow box for the first time they are often looking at the wattage of the primary light and that is included with the hydroponic system. Generally it is best to get the highest wattage HPS or metal halide light as you can. The reason for this is that the more lumens that light will put out the better the yield you will get. So often the first question out of a lot of people's mouths when a first purchasing a pre-build hydroponics grow box will ask for the wattage of the primary light. These are good questions to ask you may be overlooking a small factor.
When you are first starting seedlings or clones you do not want to put them under a very powerful light. The reason is the plants are very small at this stage of their life. A plant of this small size does not need to be overwhelmed with a super powerful high pressure sodium light which is way too much for a small plant grown in hydroponics. This is really where the vertically mounted florescent lights come in. When purchasing a hydroponics grow box try to find a unit that is sold with T5 vertically mounted florescent lights on the side of the grow box machine. Often the more vertically mounted florescent lights the better in a hydroponics grow box. Big difference to keep in mind here is that the fluorescent light put out just the right amount of blue light for your small seedlings. The fluorescent light will not overwhelm the small plant is a much better choice at this early stage of growth. The fluorescent light in the cool blue spectrum is perfect for their first few weeks of vegetative growth. Starting seedlings and clones with the vertically mounted fluorescent lights is definitely the preferred method rather than putting them under too powerful HPS or MH lights at this early stage of their development.
There are additional advantages to having vertically mounted T5 fluorescent light in your grow box besides just for starting seedlings and clones. Later as your plants begin the flowering process the plants will often grow as much as four times in size from where it was during the vegetating stage. When your plants grow this dense and bushy during the flowering portion, often much of the light will be absorbed by the tops of your plants a little will pass through the dense canopy above. That means that most of the lumens from your high pressure sodium or metal halide light is being blocked by the canopy and not making it further down the bottom of your plants where they can do some real good. Vertically mounted T5 fluorescent lights do is give you plants additional light on the underside in their vegetating stage to help them grow all those leaves and masse you will need to obtain a good yield.
Is very important that you purchase a hydroponics grow box with vertically mounted T5 fluorescents on the side so that you can start your seedlings and clones with no problem, as well as the provide additional light during the flowering portion so you will get a big bushy plant.
