We’ll start with a look at some of the most popular grow lights on the market today, then we’ll discuss some of the important factors to consider when choosing a grow light.

2X4 Grow Tent - Brightest Lumen How Much Light for a 2X4 Grow Tent - Brightest Lumen

Conversely, if your tent is shorter than average, then you can get away with using a less powerful light.You’ll need the following equipment to set up your grow tent’s lighting, ventilation, and air circulation systems: A 600 watt dimmable iPower HPS/MH lighting set is inexpensive and provides great coverage across a 2×4 grow tent canopy. You can use a 4″ inline fan and carbon filter for 2×4 grow tent ventilation. Look for inline fans with a fan controller to fine tune airflow. All of these units have enough power to properly ventilate a 2×4 grow tent. Next, let’s talk about wattage. The wattage of your grow light will determine how much heat it produces and how bright it is. A higher wattage grow light will produce more heat and be brighter than a lower wattage grow light. Our 3' x 3' grow tents are perfect for growing 4-6 full-sized plants from the vegetative stage to flowering. The compact design is ideal for growers with limited space. Your grow light will hang about one foot from the ceiling of the grow tent, and depending on the strength of your grow light you’ll need 18-24 inches between the grow light and the plant surface.

Chandra, Suman, Hemant Lata, Ikhlas Khan, and Mahmoud Elsohly. “Photosynthetic response of Cannabis sativa L. to variations in photosynthetic photon flux densities, temperature and CO2 conditions.” Physiology and Molecular Biology of Plants 14.4 (2009): 299-306. It allows you to top-vent your exhaust fan and use the side duct openings for a separate fan to air-cooled HPS/MH lighting. Features include: A 600 watt air-cooled fixture will increase 2×4 grow tent yield dramatically, with dense, frosty buds at the tent corners. We recommend getting a dimmable 600 watt unit which lets you reduce the amount of light (and heat) which is helpful when things get too hot in there. The Vivosun 600 watt dimmable grow light set costs just slightly more than iPower’s set. AC Infinity makes the best inline duct fans. All are very highly rated, powerful, and whisper quiet. The most commonly used grow bags for home-growing cannabis are three and five gallon grow bags. A good rule of thumb is to allow 2 gallons of soil for each foot of desired plant height.Consider the Vivosun mini dehumidifier if you are looking for a mini dehumidifier for grow tent use. The tank size holds 1/2 gallon of water, and it’s only rated to remove less than 3 cups of moisture per day. Keep in mind you need to remove as much water as you add to your plants each day, so unless you’re growing a real small weed plant this unit will struggle to keep up. Summary This compact grow light is perfect for small spaces and can easily be hung from the ceiling or placed on a shelf. It emits full-spectrum light that is ideal for plant growth, and it’s energy-efficient too! CFL grow bulbs and T5 fluorescent are great for short tents, such as a 2x4x5 grow tent setup. They’re gentle enough for young plants, and are useful if you want to make a 2×4 vegetation tent or mother tent. Your dehumidifier should be set up to run using a humidity controller to keep you within the proper range. The bluetooth-enabled AC Infinity humidity controller lets you control a fan or dehumidifier from your phone. Avoid using fluorescent lighting to flower weed plants. They just don’t produce enough usable light to bring out the genetic potential of your plants. Buds will be wispy and underwhelming. You’re better off running an HPS. Don’t waste 2 months flowering a plant to be disappointed, get a better light to start with and you’ll be much happier with the results.

Place the unit right inside your tent, so that the dry air isn’t being pushed right into any one plant. Use lots of circulation fans to keep air moving briskly inside the tent to keep everything as homogenous as possible. This is the type of setup you’ll need if you’re running a sealed 4×8 grow tent and supplementing carbon dioxide. The MIGRO ARAY 4 is a modular system. It can be upgraded to larger grow sizes by simply adding on additional fixtures. Added fixtures can be connected together and daisy chained for power and dimming control. Make sure that the area around the plant is well-ventilated so that the heat from the light does not damage the leaves. LED grow lights for 2×4 tents are more expensive than other options, so they’re not ideal if you’re trying to outfit your tent without spending a lot. But LED technology has come a long way in the past few years, and prices have dropped while quality keeps improving.Benefits of using a mini dehumidifier for grow tents are low prices and small size. But keep in mind that since your tent exhaust is ideally turning over the tent air every minute, using these inside the tent isn’t always the most efficient way to lower grow tent humidity. Ventilation panels with sealable velcro flaps at the bottom are needed for air intake during the vegetative stage. During flowering you’ll need to seal these off and introduce air through a lower vent hole. grow tent yield depends a lot upon the quality of the lighting you’re using, and your ability to keep the environment in your tent at optimal growing conditions for weed plants. We’ll walk you through all of that below.
