Need Help Improving Greenhouse this Year

Hi I need help trying to figure out how to combat my humidity in my 10x20x8 Greenhouse. I have 2 ecoplus 8 in duct fans 740cfm one for intake and one for exhaust. I also have two windows id rather not open but could partially open if i had to. This thing is basically a tent and I could dig or cut into pretty much as I please. If anybody could help me figure out how to reduce temp and humidity let me know. Im running 10-15 degrees above daytime temp. Last year I grew in it no bud mold at all but i had a dehumidifier but I think it was pointless because there were so many gaps in my gh. This year I sealed it up a lot better so Im scared that could be an issue? Also I put my dehumidifier in another grow so thats gone and I was wondering if I would for sure need one and if so residential or commercial? Id rather solve this problem for 300 bones or less but If i have to spend more I will I just cant lose this crop thats about to go in it any help please. My main questions: should I get a dehumidifier if so how big? Should I have two exhaust and or more/bigger inline fans? Oh yeah morning condensation sucks and the strain I chose to grow this year is not very resistant to mold please help!

interesting situation. i imagine it would be difficult to modify for the better. take that dehumidifier out if you feel it's better. try a heat sink made with buckets or drums filled with water. you know, for the dew; if it's that big an issue.

my thinking is if i had to buy another inline fan for 135 it would give me 3 fans and two windows and thus would probly give me a climate similar to the outside air at the time? I just need to match my conditions to outdoor and then if it molds it comes down to the strain because these plants will never have water on leafs period I learned my lesson to water the ground not the plant.

Why not open the windows? Smell? Bugs? Get a screen for your window? I'd think that would solve your problems pretty quickly. Uhhhhhh if it's smell, Nirvana has a strain called Blue Mystic that reportedly has little smell while flowering; could be a nice F2 to add to your greenhauz
