High humidity inside and outside the tent - 60%

I use similar size tent and have similar issues depending on times of the year. 1st improvement I made was exhausting to outside, that helped a lot. It was easy for me to do this but if it's not going to be easy for you then exhaust to a different room. 2 or 3 oscillating fans helps. The thing that helps me the most is the Dehumidifier, it doesn't fit in the tent, I have it in the room the tents in, but that does also then raise the temps slightly which could be an issue for you. Check out VPD charts and check your temp and Rh are in the suitable zone.

Managing humidity in a small grow space like a 2x2 tent, especially with a high-wattage light like a 300W, can be challenging. Here are some strategies you can consider to balance humidity and temperature: 1. Improve Air Circulation: Enhance Internal Airflow: Use oscillating fans inside the tent to improve air circulation. This doesn't lower humidity but helps prevent mold and mildew by keeping air moving. Exhaust Fan Cycling: Instead of running the exhaust fan constantly, use a timer or humidity controller to cycle it. This can help prevent the tent from getting too hot while still reducing humidity periodically. 2. Environmental Control: Room Dehumidifier: Place a dehumidifier in the room where your tent is located. This will lower the overall humidity of the room, indirectly affecting the tent's environment. Air Conditioning: If possible, use air conditioning in the room to reduce both temperature and humidity. 3. Tent Modifications: Passive Intake Adjustments: Adjust the size of the passive air intakes. Sometimes increasing these can help balance the environment inside the tent. Seal Gaps: Ensure that the tent is properly sealed and that there are no unintended air gaps. This helps maintain a consistent environment inside the tent. 4. Evaporation Control: Water Carefully: Over-watering plants can increase humidity. Ensure that your watering schedule isn't contributing to the problem. 5. Monitor and Adjust: Regular Monitoring: Use a hygrometer to continuously monitor the humidity and temperature inside the tent. Adjust your strategies based on the readings. 6. Plant Considerations: Plant Density: Too many plants in a small space can raise humidity. Ensure you're not overcrowding the tent. 7. External Influences: Ventilate the House: Improving the overall air circulation in your house can also impact the grow room environment. 8. Acceptance: Understand Limitations: In some climates, achieving perfect humidity and temperature control can be very challenging, especially with limited equipment.

Hi there. I have just bough the FC-E 3000 and I run it in a 3x3. I have a 2x2 and run a 200w. To address the heat I would dim your light first. In veg you want about 20-30w per square foot and in flower no more than 50w. I would start dimming your light right down, get a smaller light or a bigger tent. Either bring air from outside or exhaust outside. Never have any water laying in trays or puddles. I was thinking of putting the 300w in the 2x2 or the tsw but it's just too hot. Try a phone app for light intensity. A dehumidifier does also help. If you can have it to drain constantly it helps as they fill up quick. Plants only use about 3% of water you give so have this in mind when sizing the dehumidifier

Are you running your exhaust out of the room/house? Doing that helped me lower my humidity from the 60s down into the 40s.

Better intake and out take fans is the key to lower humidity or you can bite the bullet and buy a small de humidifier that is another option there is always the option of adding more air curculation fans to try and get the warm moist air out the tent quicker the choices are yours buddy best of luck :)
