How Many Cannabis Plants Per Square Foot?

HOW MANY PLANTS CAN I GROW PER SQUARE METER? Before you get your grow on, you need to have a plan and a timetable. First, you need to establish the size of the available grow space.  Hydroponic grow tents  come with exact dimensions on the box. However, if you are building your own grow box, or converting a whole room into a grow-op, you need to first take measurements. Next, you must decide how much light you can put down while still maintaining optimal environmental conditions. We will breakdown the key factors to consider when choosing grow lights a little later. Perhaps the most important question the grower needs to ask him/herself is; how much time can I commit to cannabis cultivation? Work, family, and social commitments can make growing a difficult balancing act. A large sativa plantation will be far more time-consuming to maintain than a couple of autoflowering plants in a wardrobe. The genetics you choose and your preferred grow style will ultimately determi...

Advanced Platinum VS BLOOMSPECT 300W LED Grow Lights

Things to Consider Great value usually comes in small packages. With a 300-watt row light, you can utilize a small space to grow high-quality cannabis. These lights are almost always energy efficient and stay cool because of their size. But, what creates great value is the full spectrum of light, infrared, ultraviolet, and par map. You should also consider the intensity of lights. You want a light that will most closely mimic the suns natural rays! Full Spectrum It’s difficult to guide new growers in the direction of lights because nearly every product claims to have a “full spectrum,” but there are a few problems with that. First, there’s no such thing as a perfect spectrum. Second, no entity tests these lights out to ensure the manufacturers’ claims are true. Finally, not every strain needs every wavelength. There’s no perfect spectrum, and the LED quality and volume of light emission varies by manufacturer. So what do you do to ensure that you get the light’s that are bes...

What kind of spectrum is needed to grow cannabis?

What is a Light Spectrum? The visible light spectrum falls between 380 nm to 750 nm (nanometers). This is the spectrum that we as humans can see, but plants use an even broader spectrum of light for photosynthesis. Plants can ‘see’ ultraviolet wavelengths to infrared, and everything in between. In normal outdoor growing conditions, the light spectrum shifts subtly through the seasons. From spring into fall, the light shining on plants determines how they grow. As the seasons changes, plants are triggered to enter into vegetative and then flowering stages of production. 180-280nm - UVC: Extremely harmful and luckily almost completely absorbed by the ozone layer 280-315nm – UVB: Cause of sunburn and suspected to increase THC levels (!) 315-400nm – UVA: Not absorbed by the atmosphere, commonly known as black light 380-750nm – The visible light spectrum: Bands of wave lengths represent visible colours 700nm-1mm – Infrared light: Not visible above 750nm but noticeable as heat on ...

What light is best for seedling growth?

WHY WOULD I WANT A GROW LIGHT FOR SEEDLINGS? Seedlings need both even lighting and proper temperatures to ensure vigorous, strong growth. Spring months are often unpredictable. Your home may have varying degrees of sunlight and temperatures that can affect growth rates of plants. One trick is to keep your seeds facing the window so they get the length of daylight they need. With a grow light you can grow anywhere without worry of seasonal changes or window placements. You also can set up a room, or a small tent to support your seedlings as they grow- and deter your pets (or children) from making a mess of your young plants. Why You Should Use Grow Lights For Seedlings An excellent way to make sure that your seedlings would grow healthy is to use  grow lights  instead of relying on natural lights alone. If you want to ensure rapid, healthy growth of your seedlings after germination then using grow lights can make all the difference. If you’re trying to grow multiple seed...
