Hello my good banana-folks! I'm looking for some EXPERTS to help me with some AVERAGE TEMPS. and RELATIVE HUMIDITY LEVELS for my small 8' x 4' greenhouse here in Illinois! It is FINALLY allmost finished! I'm planning on haveing 4 pineapples/4 pomegranates/and 4 papayas in it over the course of the winter! Right now it is 28 degrees f. outside and 59 degrees f. w/48 relative humidity on the inside (of greenhouse) at 10:00 p.m.! I'm thinking cranking it up to about 68-72 degrees f. and possibly the same 68-72 relative humidity would this be proper? Only 1 (one) foreseeable problem, when the sun is nice and bright it does get up to 90-105 degrees f.(for 2-3 hours) in there, but i have my misting solution allmost completed!
PLEASE LET ME KNOW!
THANX ROBBY
P.S. My pineapples are just pre-rooted tops from store bought-papayas from seed from Fla. (what a great state) and the pomegranates if i can find them, seeds from the kind that grow in the snowy regions in Iran such as turkmanestan=(spelling)!

Pomegranates will tolerate excursions into the 20's (F).
Pineapples will tolerate brief visits to 35 F, provided the roots are not soggy.
Standard papayas generally die below 40. There are a few frost hardy varieties of papaya (Carica papaya) and also some non-Carica papayas that tolerate excursions into the high 20's; for example Babaco aka Pineapple Papaya.

For pomegranates, the hotter the temperature the less humid it should be. When the temperature exceeds 85 F, I would keep the temperature from exceeding 75%. For temperatures over 100 F, I would keep the humidity from exceeding 60%. Under these conditions, pomegranates will handle temperatures well over 100 F.
Pineapples will tolerate high humidity when the temperature is very warm or hot.
Papayas will withstand high humidity with warm temperatures but are less tolerant of extreme heat. I would keep the temperature from exceeding 95 F by installing a servo-controlled vent.
