  • 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 and will temporarily stress out when adjusting to them. Let's take a look at some common grow tent heat problems and how to remove excessive heat from your grow tent or grow room.

    Controlling temperatures is one of the single most important aspects of growing, and 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?

    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. Continue reading

  • Different Types of Grow Light Bulbs

    There are many different types of grow lights and grow light bulbs on the market. There will be different factors that you need to know about depending on the lighting option you choose. The two main factors you will look at is wattage and spectrum.

    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.

  • How to Hang Your Grow Lights

    How do you hang your grow lights? Its 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 beam 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.

  • Growing with LED Grow Lights

    LED stands for light-emitting diodes. LED grow lights have rapidly come down in price and home growers everywhere are starting to make the switch to solely using them as their lighting option.

    Maybe you don’t care about leading the charge, and you simply want a lighting system that produces extremely low heat, comes ready to plug-and-play, and can produce high yields with incredible energy efficiency. If so, look no further because LED is the perfect lighting option for you.

    For calculating cost, expect to spend $1.50-$3 per watt depending on quality and brand. Remember that while most LEDs cost more per watt than HID lamps, they do not require a reflector or ballast. As well, LED lights last for decades where HID bulbs will often need to be replace every couple of years. Continue reading

  • How to Use Grow Light Movers

    All growers want to find ways that they can improve their process and help their plants to grow stronger and healthier and as little time as possible. While there are a range of factors that contribute to plant growth, light is one of the most important for indoor growers. They cannot rely on the power of the sun to take care of their light needs, and they need to supplement with grow lights. However, the lights and reflectors often used can only do so much. Therefore, many have taken to using a device called a grow light mover.

    These devices are an effective way for growers to distribute the light intensity over the growing area more evenly, and they tend to be relatively easy to use, although they will require installation. While it is possible to move the lights manually, you will find that automating the process with all the right tools can help to make your life much easier. Continue reading

  • The Best Grow Lights

    Grow lights are the single most important piece of your indoor grow room - lets break down the best grow lights. Those who are going to grow plants indoors need to think about the grow lights they are going to be using. It is important to remember that even though they might all seem to be the same to the untrained eye, not all light is equal. Plants will grow better depending on the type and color of light being used, which is one of the most important factors to consider when you are choosing the best indoor grow lights.

    Metal Halide and High-Pressure Sodium (HID) Grow Lights

    The HID, or high intensity discharge, lights for growing are popular amongst many growers today. The two main types of lights that fall into this category are metal halide and high-pressure sodium. The biggest difference between these two types of lights are that they will fall at opposite ends of the spectrum. The metal halide lights emit a cooler blue-white light, while the high-pressure sodium lights will emit a red light. Many growers find that having both lights is a good option. They will utilize the MH lights during the vegetative phase of the plant’s light, and the HPS lights for the flowering phase. For those who only want, or who can only afford, one of these types of lights, the HPS lights are the better option overall. The most popular of these types of lights are 600W, as this provides a nice balance of light emitted and efficiency for electrical consumption. Continue reading

Here you’ll find the best of the best when it comes to grow lights for commercial operations. Double ended HIDs and CMHs rule the commercial gardening world and are still unmatched by LEDs when it comes to large scale-operations. As such, at Hydrobuilder we focused this category on providing you with the best DE and CMH bulbs, fixtures, and everything else need to get them up an running and growing plants that rival all other operations big or small.

    Because these are commercial grow lights, the majority of the lights in this category are operated on 277 volts or 480 volts. As well, the majority of these lighting units fall under either 315 or 1000 watts. 315 watt DE or CMH bulb will rock a 3 x 3 with ease, while 1000 watts are perfect for filling out a 5 x 5.

    I’m not a commercial grower - will these lights be too much?

    Yes, and no. it’s will depend on the size of your garden, voltage of the lighting fixture, and the light demands from your crops. Many serious home gardeners have grow spaces that are around 4 x 4. This allows them to grow multiple large plants at a time, while also ensuring that each plant has enough space to grow unhindered. For a space this large, you’ll need a lot of light – it’s recommended to shoot for a 1000 watts from an HID just to fill out your lighting footprint. Continue reading
