How Many Lights Should I Invest on My Grow Tents?

As we all know, grow lights play an important role in your grow room tent. However, how many grow lights do you need on earth? We are here to make it clear for you.

If you are new grower looking to produce your own fruit and vegetables, make sure how many grow lights tent to be more essential. It can take a long time for a new grower to find a great grow room setup and it usually comes after you have learned by doing. The amount of lights you use depends on the size of your grow room, the amount of plants you are growing and the power of the lights you purchase.

On the one hand, the higher the wattage on your lighting system will usually result in a higher yield. For example, a 400w system usually grows 4 or 5 plants in medium, 2 gallon, sized containers where as a 1000w setup could hold almost double the plants in larger 4 or 5 gallon containers.


On the other hand, it is important to know that the higher price of a high watt system isn’t the only cost. More powerful lights means more heat generated and having a hot grow room could badly affect your crops. If your grow room budget allows you to purchase a high powered lighting system, be ready for the extra cost that comes with cooling your grow room down.

If you cannot afford 1000w lighting, don’t worry because a 400 or 600 watt lighting system still provides efficient lighting with reduced heat. However if you do have the money to purchase both powerful lights and a method to reduce the heat, it is more likely you will have a larger and better yield.

For the best temperature for a grow room, it is around 21 – 23 degrees. If you purchase powerful lights without a cooling system in place and the temperature gets too high, the quality of the fruit and vegetables produced in the environment will be lacking. Always keep the lights within your grow room a couple of feet away from the plants otherwise they could be seriously damaged. A good way to determine if your lights are too close to your plants is to place your hand on the tops of the crop and if you feel the heat, the lights are too close.

With these basic tips for lighting within your grow room, it should be a little simpler when it comes to setting up.  If you are new grower in grow tent gardening, the above knowledge of lighting will be helpful.

Cultivating Vegetables in Grow Tents

In cooler northern climates, warm summer weather may not last long enough to grow some warm season corps. Gardeners can extend the season with elaborate green houses, but the effort and expense may be too much if you’re not planning to grow a large garden. If you’ve got a more modest garden in mind and a smaller amount of expenses you can afford, using grow tents for plants is a logical alternative.

What is a grow tent? The shape and design may vary, but it is basically a portable frame covered in thick plastic sheeting, designed to capture and keep in heat to encourage plants to grow longer.

Grow Tent Benefits

Whether they’re temporary or semi-permanent, grow tent benefits are the same. Capturing heat and holding it in an enclosed area creates a mini climate, which allows plants to grow longer than your outside environment would naturally allow.

In the spring, setting up a grow tent in your chosen planting area allows the ground to heat up and dry out faster, allowing your plants to be transplanted earlier in the season. This can give you an additional two to three weeks at the beginning of the growing season. It also offers a sheltered environment for hardening off early seedlings before placing them in the garden.

At the end of the growing season, grow tents can hold in enough heat to allow the last of your harvest to ripen before the frost arrives. The last of your tomatoes and peppers, and even your potato plants, will be able to live longer and produce more food in the longer artificial season.

Tips on Using Grow Tents for Plants

When you research information about grow tents, you will find that the design varies from gardener to gardener, and is only constrained by the imagination of the builder. Because of these differences in design, there will be various things to consider, or additional concerns that need to be addressed. For example, you may wonder about the temperature difference within the grown tent as opposed to that outdoors. This, of course, is dependent not only on the type of grow tent being used but the conditions outside like sun vs. cloudy weather. For this reason, you may find it helpful to include a thermometer inside the tent to monitor these conditions.

You may also wonder about when to open or close the door of your grow tent and the effect this has on the plants inside. Again, this varies on weather (and the plants grown) but generally, if it’s nice outside for the plants you have, opening the tent some to allow for a little airflow will not hurt anything. Close the door when temps fall below (or are expected to) the acceptable conditions for the plants being grown. It is best to close the door a few hours prior to the setting of the sun so that the tent has a chance to build up enough heat to keep it warm overnight. Once closed, heat and moisture will be trapped inside. While the sun is out, this heat continues to build but also remains when darkness falls.

Soil Or Hydroponics?

Different growers succeed with various growing methods, so you must decide for yourself whether to grow in hydro or soil.

For soil and soilless mixes, you can grow in pots, grow bags, fabric containers or large beds. You might need to install a drainage line in the side of your tent near the base. This soilless bed garden is equipped with drainage, which is plumbed out of the tent. Heavy-duty casters are used to shift the garden a few inches in any direction. If you choose hydroponic grow tents for your plants, consider raising your tent off the floor—you can support the tent with tables or build a frame. With the tent raised the hydroponic reservoir can sit directly on the floor under the tent, which will keep your nutrient solution cool as it will not be heated by your grow lamp. In general, reservoirs will stay cooler when kept on a concrete floor. Nutrient solutions should always be at 72°F, or slightly cooler. Your hydro tray will sit on the floor of the tent, giving you maximum vertical space for plant growth.
