  • How To Measure Grow Light With A PAR Meter

    Are you aware of just how effective your grow light is? If you are growing indoors, you need to understand how to measure your light with a PAR meter. Light is one of the most prominent factors in how your plants grow, and so it is important to constantly be testing your light output.

  • How to handle excessive heat in your grow tent

    Not too hot and not too cold; many of the plants we grow are just like us and prefer similar temperatures — between 65 to 85 degrees Fahrenheit.

    Also, like us, they hate extreme temperatures changes. Plants will temporarily stress out when adjusting to them.

    Controlling temperatures is one of the single most important aspects of growing. If you fail to do so, you will wreck your plants nutrient uptake and weaken them to diseases before they eventually die. How about I show you how to avoid this?

    Let's take a look at some common grow tent heat problems, and how to remove this heat from your grow tent or grow room.

    Never Grow Without A Thermometer / Hygrometer

    A thermometer and hygrometer are essential to every indoor garden. Locking your plants into their preferred temperature and humidity ranges is crucial for nutrient uptake.

    If your vapor pressure deficit (VPD) is off (air temp + leaf temp + relative humidity), then your plants will either drink and uptake too much or not enough nutrients. It’s common to see calcium deficiencies because transpiration is largely affected.

    If this happens, you can use a cal-mag supplement. But you will need to address the root cause eventually as well.

  • Different Types of Grow Light Bulbs

    There are many different types of grow lights and grow light bulbs on the market. Different factors will affect which grow light bulb is best for you. The two main factors you should consider are wattage and spectrum.

    Bulb Wattage

    Figuring out the wattage you need will depend on tent size, plant coverage, and light type. The last one is important to remember and not all light wattage is created equally. A 200W HID delivers lights much more efficiently than a 200W CFL.

    As a general rule of thumb, you’ll want a minimum 23-30 watts of light per square foot. If you have a grow space that is 4’ by 4’ you’ll want at least 400 watts to fill the space. Since fluorescents are weaker you’ll times that by 5, so 115-150 watts per square foot.

    Bulb Spectrum

    Color temperature has a strong influence overs plants and different temperatures will affect plants in different ways. A blue or bright white found in the temperature range of 5000 K is recommended for plants in the vegetative stage as it keeps them short and bushy.

    The temperature range around 3,000 K that produces a yellow or red light is strongly recommended for flowering plants. If you can only afford one temperature for the entire growing period, it’s recommended to stay in the lower range of 3,000- 4,500 K.

  • How to Hang Your Grow Lights

    How do you hang your grow lights? With the right tools, it is actually very easy!

    When you are hanging your grow lights, there are several different methods that you can use. The one you choose will be determined by the setup you have in place, and whether you have any available beams for your growing room.

    Those who have beams can install the lights, or a grow light mover system, right onto the beams.

    It is possible to use screws and hooks added directly to the beam. Just make sure they are strong enough to hold up the lighting system you plan to use.

    Those who do not have beams will want to purchase a frame that they can place over the top of the lights, to which they can then affix the lights.

    While this method might be more expensive since you will have to buy a frame, or frames, you will find that it provides you with more freedom, as you can more easily move the entire setup to a new area if needed. Continue reading
