Grow Tent Tips

Grow tent tips

Put wet sponges in the tent to more quickly raise the humidity. Soak the sponges in water, then set them near any fans or air vents inside your tent. The heat and air flow will cause the water to evaporate over time, increasing the humidity level.

Do you leave fan on in grow tent?

Running your fan during different plant growth stages At this time, we recommend you run your fan 24/7 to maintain temperature, humidity, and fresh air inside the tent. In addition to an inline fan, we also recommend having a gentle oscillating fan in your tent.

How often should you change the air in a grow tent?

Air in your grow area should be exchanged at least every 5 minutes. If you are using a grow tent that is 5' x 5' x 6' this is 150 sq/ft of air. For optimal airflow, you need a filter and fan that can move between 30 and 60 cubic feet per minute (CFM). It is also important to balance the flow in and out of air.

Do grow rooms need to be air tight?

A sealed grow room must be sealed from every corner. You need to seal every hole or place from where the air can enter or escape. Sometimes, a few holes or places are left, or they might get open after some time. Therefore, you also need to take care of the leakages and draughts and make sure everything is perfect.

Should air be blowing in or out of grow tent?

Consequently, you'll need to provide a constant supply of CO2 for your plants to grow. This means creating air circulation to bring in that fresh air. Ventilation is a two-part process: intake and exhaust. While air is blown out of grow tents, fresh air comes in to maintain good air quality.

How do you keep the humidity constant in a grow tent?

Using a spray container, mist the air inside the grow tent multiple times. As the water droplets evaporate, they will raise the humidity level inside the tent. In order to keep the humidity at a constant level, mist the leaves and roots of your plants every day.

Where is the best place to put a fan in a grow tent?

Your intake fan or vents should be at the bottom of your tent. Your extractor fan should be high, towards the back of your grow room, on the opposite side of your tent to yout intake fan or vent.

The best grow room temperature during the vegetative stage of growth is 70-78 degrees F. when the lights are on during the “daytime” and no more than 10-15 degrees cooler at “night” with a relative humidity of 45-55%. With these settings, your plants will best be able to convert light into energy for growth.

What happens if grow tent gets too hot?

Failing to fix an issue with your grow tent being too hot will weaken your plants nutrient uptake and leave them more susceptible to diseases before they eventually die. Let's take a look at some common grow tent heat problems, and how to remove this heat from your grow tent or grow room.

How often should you water plants in a grow tent?

We recommend watering every 2-3 days, but test your soil as usual to see if your plant even needs water.

How often should I exhaust my grow room?

Ideally, your extractor fan system should replace the air in your grow room every minute, or at least every three to five minutes.

How do I get fresh air in my grow room?

Intake fans- They draw in fresh air from outside into the grow room. Oscillating fans– They help circulate the air drawn in by the intake fans. Exhaust fans- The fans act like a vacuum and suck the stale air out of the room. Inline fans– These fans allow the warm air to escape while bringing in the fresh air.

How hot is too hot for grow room?

In both cases, maintaining stable temperatures is vital. The recommended room temperature when lights are on is 68-77°F (20-25ºC), and 59-68°F (15-20ºC) when lights are off. Temperatures above this are likely to become too stressful for the seedlings and clones.

How cold is too cold for a grow room?

A cold grow room will likely slow down the growth of your plant. As a general rule, temperatures lower than 55-60F (10-15C) will slow down and eventual kill your plants.

How many air changes per hour in grow room?

In general, you want the air in your grow room to circulate at least 8 to 9 total air changes per hour. That means if your grow room is in a spare bedroom that measures 8' x 8' by 7', that's 448 cubic feet. for 8 air changes per hour, that's 3584 cubic feet per hour.

If you are looking to accelerate the grow cycles of your crops consider adding additional CO2 to your grow room. Plant growth accelerates as you increase CO2 levels up to around 1,500 PPM.

When should you close tent vents?

Its important to pick a tent with plenty of ventilation, as it will breathe more, and make the camping experience more enjoyable. Keep all vents open on the tent at all times to allow it to breathe. Use a fan such as the Christianos fan to negate condensation and create airflow.

Do fans lower humidity in grow tent?

Improve ventilation by adding more fans It could also be as simple as venting a duct fan or opening a window to push moisture out of the grow tent. I've observed that this option only works to lower humidity if the intake air has a lower RH than the air in the grow tent.

How do you control humidity in a grow tent when the lights are off?

If your humidity levels are too high even when your lights are off, using a dehumidifier, watering less, keeping the number of plants down, and promoting good air circulation throughout the tent will all contribute to maintaining lower humidity levels.
