This is my first attempt. I've set up a 4x4 tent with 2 ES300 lights. I'm in a super dry area and with the lights both on I get some pretty high temperatures (85-90) so I've added the AC. I'm having two problems that I need help with.... With my exhaust fan turned up 75% of the way and Taotronics humidifier set to 80% I can't seem to get my sensor to read humidity greater than 40-50%. The other is more of an experience question...Are other people that are using these lights following the manufacturers specs for height and intensity or have you seen better results with different settings.
I haven't started my seeds yet as I want to get my environment tuned in so I dont ruin everything by jumping the gun.
I am new to growing also and sure hope you post your progress because I am wanting to get those very same lights.
Hi Scott, good questions. For the humidity issue, you may want to try lowering the speed of your inline fan while the AC is on so more cool air will stay in the room. Also, since you're exhausting less air, the humidity will increase since it's staying in the room longer. If that doesn't work, there are a few alternate ways to increase relative humidity. You can hang wet towels in the room. As the towel dries, H2O is evaporating and therefore increasing the relative humidity. You can also place containers of water in the grow space as well. I just re-read your post and realized you don't have plants in the grow space yet. Having plants in there will also increase the relative humidity via transpiration. So if your environment is slightly off to where you want it to be, the addition of plants may land it in the sweet spot. For the ES300 question, I've ran 18" at the closest while flowering. I feel like 20-22" provides a bit better light spread and reduces the risk of too much light that sensitive strains don't handle well.
