the tempature in my grow box fluctuates between 75 and 85 the humidity is usually between 20 and 40, 1. is it ok for the tempature that much? 2. is the humidity high enough and 3. does the positioning on my thermometer make a difference?

"Both excessively high and low temperatures can slow marijuana's rate of metabolism and growth. The plants function best in moderate temperatures - between 60 and 85 degrees. As more light is made available, the ideal temperature for normal plant growth increases. In high temperature and moderate light conditions, the plant's stems elongate. Strong light and low temperature conditions will decrease stem elongation. During periods of low light, sem elongation can be decreased by lowering the temperature." Thank you Mr. Ed Rosenthal

And humidity IMO best 60-80% veg, and no more then 30-40% for flowering.

What do you consider expensive? I would invest in a small humidifier if I were you. $20-30

I dont think that it will cause a "problem" its just about getting the most you can out of the plant.

,and dont go and buy a humidifer and will take water and energy from the plant slowly killing your plants
a humidifier can be a great asset. It will in no way harm or kill your plants, as long as it remains within the acceptable range.
I believe 40-60% is considered "ideal", but is acceptable outside of that range. For flowering, I recommend a lower rel. humidity.(20-30) It is believed drier conditions support more potency, and it will reduce the chanc of budrot.
