What is a Grow Light?

Grow lights are used to simulate the growth of plants and seed sprouting. These appliances are used for amateur and professional gardening to help people prepare seedlings for their further planting. As you know, plants need sunlight and warmth to grow, and the more light they get, the better they grow and the higher yields they provide. Yet, winter is the period of long nights and cold weather and everybody knows that plants can't grow in winter. That's why people build greenhouses and conservatories equipped with grow lights - plants grow perfectly well even in winter there! If you are passionate about plants or flowers, read our brand-new review on the best grow lights and make your choice!

Apollo Horticulture GLK1000GW19 Grow Light

Plants Have Never Grown So Quickly Before

Apollo Horticulture is proud to present this amazing grow light system that has an incredible power and, therefore, efficiency. The kit includes the following components: a reflector (ensuring the coverage area of 6x4 feet), a 1000-Watt power supply unit, and a couple of lamps. Also, the grow light has a dimmable option, which means you can choose the light intensity level: 50%, 75%, or 100%. There is also a timer (1-24 hours) which you can set to work for a certain period of time and switch off automatically. We find 2 lamps in the kit highly important as the MH lamp is more efficient during vegetative growth whereas the HPS lamp is more useful during the ripening of fruit. As you can see, the light intensity ensures the quickest growth of your plants. You can grow your favorite all-natural plants for your family all year round.

Any lamp has its lifespan and one day you will need to replace it. That's why we recommend you to purchase a couple of spare MH and HPS lamps in advance. This way you will be able to provide your plants with sufficient light even if one of the lamps fails.

The VIRASPECTRA grow light provides an ideal combination of a well-thought-out reflector and light, making the unit capable of covering the area of 2x2 feet. Yet, you can place a lamp higher so that the coverage area amounts to 3x3 feet. As for the light panel, it encompasses 60 LED bulbs with the overall power of 300 Watts. If it isn't enough for you, you can pick a more powerful version of the grow light from the same manufacturer. Moreover, you can get a special grow tent in order to provide the maximum amount of light to your plants. Also, you can purchase and connect a timer that will shut the lamp off automatically. It's a truly handy option! Moreover, plants require a certain level of moisture so you should use a hygrometer, too.

Today's world is becoming more and more nature-aware and this grow light boasts a truly low power consumption - just 136 Watts. The similar HPS / MH lamp would consume around 250 Watts. Less energy spent means lower electricity bills for you, so get this unit right away!

Hydrofarm Jump Start JSV4 T5 Grow Light System

All You Need For Growing Plants

The Jump Start JSV4 grow light system will be useful for gardeners who wish to maximize the growth of seedlings in their conservatories or greenhouses. The package is shipped really fast and contains everything you need for assembly. Unlike some other grow lights, this unit requires no additional parts or tools. The whole structure (when assembled) is 4 feet wide - enough to place lots of seedlings. The T5 fluorescent lamp is also included in a package. With the help of this grow light system, you will be able to grow seedlings of plants and flowers 15-20% faster thanks to the efficient lamp and reflector. We would like to draw your attention to the height adjustment mechanism - you can lift the lamp up or lower it to be closer to the seedlings. All you need to do is pull the cord down and fix the right position with the help of a clamp. It's simple as it is! Experienced gardeners recommend keeping the lamp 3-6 inches above the soil till the seeds come up, then lift it gradually along with the growth of seedlings. To make seeds come up as quick as possible, you can use a special heated grow tray.

iPower GLSETX600DHMAC6 Light Digital Dimmable System

Thought-out to the Last Detail

The iPower GLSETX600DHMAC6 is an easy-to-use grow light system which is not only efficient for growing seedlings but also extremely safe in use. In fact, the iPower has a truly thought-out design and we are going to tell you why! First of all, the reflector has a slide-in glass that protects the lamp from any impact. Such design solution adds to durability of the lamp and also stands for the safety of use. If you've got little children, you know well how much they like messing around, so they might easily scorch themselves if a grow light is equipped with MH / HPS lamps. Yet, this iPower grow light system protects kids since it has a slide-in glass that prevents any access to the lamp. We would like to note that this iPower model has two lamps - MH and HPS - that boost germination of seeds and growth of plants. Of course, you can choose which lamp to use depending on what kind of plants you grow. If you have some experience in gardening, you know well that some plants need more light whereas others need less. The iPower grow light system allows you to adjust the light intensity: pick one of 3 available modes - 50%, 75%, or 100%.

Finally, the last tip for you: if you apply fertilizers, don't forget to wear a dust mask that will protect your respiratory system from the finest particles.

The DuroLux DL824 grow light allows a daisy chain connection - you can buy multiple lights, connect them, and grow a lot of plants at a time.
