The biggest factor to increase 2×4 grow tent yield is to maximize overall canopy space. There are only 8 square feet for buds to form in this size tent. And unless you have a powerful grow light such as a 600 watt HPS or expensive LED, the usable light on the corners of the tent is lower which greatly impacts bud growth and density. Underpowered lights mean thin, wispy bud development, which will decrease yield from 2×4 grow tents.
2. Growing environment
Maintaining optimal humidity and temperature levels with adequate ventilation and circulation is a must. Learn how in our guide on how to set up grow tent ventilation systems. Your goal is to make sure to keep your plants in optimal ranges to facilitate photosynthesis.
3. Light intensity and penetration
Better lights equal better 2×4 grow tent yield. Go with a powerful light but make sure you can deal with the heat.
Understand the optimal distance to place your light. The inverse square law applies to grow lights. Closer placement to the canopy equals more intensity below the fixture. Raising the light raises intensity at the edges while reducing it in the middle.
4. Watering and nutrients
Proper watering and nutrients is essential to bring out the genetic potential of your cannabis plants. Observe your plants daily for signs of deficiencies or for nutrient burn, and adjust nutrients as needed. Learn more about nutrients for growing weed.
If you’re growing in soil, make sure not to overwater, let the medium dry out between waterings. Building a strong root system throughout vegetation will deliver a higher yield in 2×4 grow tents.
5. Plant training
Training plants into a flat, even canopy develops more surface area for bud development, maximizing yield in a small space. Top seedlings or clones early to encourage lateral branch growth and help form a bushy vs. pyramidal shape.
A screen of green setup using a trellis net is an easy solution to train branches into an even canopy. A very cheap solution to for low-stress training for young plants is to use twisties with bamboo skewers or stakes.
Experiment with more advanced training techniques as you get comfortable with the basics. But at the very least, top your plants and lollipop them.
6. Lollipopping
Lollipopping is the practice of completely stripping the lower growth of cannabis plants during flowering. This lets the plant focus energy on the top areas that receive direct light. All lower fan leaves are removed, and bud sites are pinched out.
Generally at least the lower 1/3 of the plant is removed, but on taller plants you may need to do more. Remember your plants will stretch during the first few weeks of flowering, which will further block the lower growth. So don’t be shy about removing that growth before initiating flowering.
7. Genetics
Look for strains known for being heavy producers if you want to maximize 2×4 grow tent yield. Some indica hybrids are known for heavy yield with dense, compact growth. Some sativias will stretch a lot and have lots of space between nodes, minimizing bud production.
Choosing genetic wisely will ensure that you are working with plants capable of delivering high grams-per-watt output.
Summary: How to maximize 2×4 grow tent yield
There are lots of factors that determine 2×4 grow tent yield. Your goal as a grower is to create the ideal environment to provide optimal growing conditions. Combined with proper nutrition and plant training you can get the most out of your cannabis plants.
If you’re a new grower and looking to purchase all of the equipment you need to grow, consider a 2×4 grow tent kit.
