I would like to introduce you to my new seedlings. I have changed my lighting arragement as the l000w was generating too much heat and removing all the humidity in the tent. Even with the flaps opened and a fan running the earth was constantly dry. Temperatures were in the 90's and humidity was 20. With this new arrangement the humidity is around 35-40 but the temperature is 68. Is this warm enough for these seedlings? I was planning on leaving lights for 18 hours on and 6 off. With the lights off the temp is sure to go down lower. I am using 3 100w cfl. Should I leave lights on 24 hours for a while to make sure they stay warm. Please give me your expert advise. Thanks
