A weatherproofing film kit made to be used over windows might work. Something like this - https://www.amazon.com/Duck-Indoor-84-Inch-120-Inch-282450/dp/B000NHW2Z6/ref=zg_bs_495374_2?_encoding=UTF8&psc=1&refRID=CD4K071GXSESC5PCDPGF

30" shutter, its nice quality with some visible openings in corners around 1/8" - so not completely sealed.

I have smaller 8" vents with draft dampers that I will be using in the cold months with the large shutter insulated and sealed off.

Good news, GLASS! Glass is great for heat. Bad news, we're both in the PNW and expecting a nasty winter. (Okay, so they've been telling us to expect a nasty winter for 3 years running )

An electric heater with a thermostat is perfectly safe. You will probably only need a small heater. I have a 6'x6' and I use a small heater with a fan connected to a plug in wifi thermostat: https://www.amazon.com/gp/product/B0811LWW4D/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

This turns the heater on at 60, turns it off at 70. I've had it on my wooden porch for 2 years, no problems. THe heater has a tipover shutoff in case a random animal makes it through the door or the wind gets so strong it goes over. The thermostat unit tells me what temp the greenhouse is at every moment so I can respond to it if the temp drops too far.

If you are putting up a greenhouse like this: https://www.amazon.com/Greenhouse-Indoor%EF%BC%86Outdoor-Shelves-Portable-Gardening/dp/B08C2CNK3H?ref_=ast_sto_dp&th=1&psc=1

It is entirely possible to protect the top of the greenhouse by using sheets of clear polycarbonate (Either twinwall or corrugated). You can ziptie these to the inside after you cut them to size and it will protect your plants in case a branch comes down. If you do it to the outside, you will have to create a little roof structure, make sure the panels are connected together and secured from blowing away.

I bought this guy and I love it, but… definitely needed to be shellacked, better hardware (pieces rusted) and no ventilation. I really had high hopes because it’s so cute and perfect for the small space that I have.

Picked this book up before we got too involved in our greenhouse and it really opened our eyes to ideas and problems I had not thought about, worth the quick read I think. https://www.amazon.com/dp/1539126196/ref=cm_sw_r_apan_i_FG2TTD7JCS6WKN36TX1P?_encoding=UTF8&psc=1

An indoor grow tent sounds like what you're looking for: VIVOSUN 4x4 Grow Tent, 48"x48"x80" High Reflective Mylar with Observation Window and Floor Tray for Hydroponics Indoor Plant Growing for VS4000/VS4300 https://smile.amazon.com/dp/B01731MNJE/ref=cm_sw_r_apan_glt_i_JEJBWKN3Z0KGS5TP62FD?_encoding=UTF8&psc=1

They aren't meant for display purposes but your plants will love it!

Well depending on your needs one thing I’ve used that is power free and more useful than the fans in my opinion is the automatic green house window openers https://www.amazon.com/dp/B071VYQ91P/ref=cm_sw_r_oth_api_glt_i_6PTDHEXJQW1DB7GP8AD3

I had regular Honeywell vortex fans in mine but the vent windows work much better at venting heat passively believe it or not

SensorPush HT1 Wireless Thermometer/Hygrometer for iPhone/Android. USA Developed and Supported Humidity/Temperature/Dewpoint/VPD Monitor/Logger. Indoor/Outdoor Smart Sensor with Alerts https://www.amazon.com/dp/B01AEQ9X9I/ref=cm_sw_r_cp_api_glt_fabc_6TSC01AGF99DRTDGRRPS?_encoding=UTF8&psc=1

I don't really want to spend more than $175-$200

Right now out setup is two iLIVING 12" shutter exhaust fans with Thermospeed fans in the greenhouse to control the temperature. I don't think we have a plan to deal with humidity yet.

It is our first experience with a greenhouse and we are still figuring a lot of things out.

I bought 2 of the short version of this cabinet and have my indoor setup in them. I have 2 mini desk fans running constantly in them, removed the side glass panels off of the sides that face the opposite cabinet so that there is air flow through the space between but not too much humidity loss, and have these lights stick on with outdoor command strips https://www.amazon.ca/dp/B0811VX52Z?ref=ppx_pop_mob_ap_share.

I get temps up to 28c and 50% humidity which my hot peppers love. They are flowing since bringing them in 1 month ago. I'm constantly pruning because the space is very small, but the plants are thriving!

I hope this helps!

Sounds like you made the mistakes I did 15 years ago. You want to seal the top with aluminum tape, but you don't want to seal the bottoms. Sealing both ends can cause cracking due to air expansion. The bottom should be sealed with a fiber tape so that air, and moisture can escape as the temperature changes.

Might be this

There is also this book

For those looking for the link here is an amazon link

For those not wanting to frequent amazon the model number etc

Manufacturer: Palram

Model: HG5504 (or HG5504G for the Green not Silver version)

Dims available: 6'x4', 6'x6', 6'x8', 6'x10', 6'x14' all at 7' tall, looks like most of them come with manual vents built in but they sell an automated vent add on (cant find an active link for those atm)

Price range for the dims is 420-1600$ depending on where you are ordering from and if it's Green or Silver.

I added one of these - https://smile.amazon.com/Solar-Powered-Attic-Watt-W-Ventilator/dp/B00M0NI4PS/ref=sr_1_3?keywords=solar+powered+attic+fan&qid=1554429795&s=gateway&sr=8-3 to my greenhouse.

At 86 degrees F, it kicks on and really does well to pull the hot air out and pull the outside air through side vents.

Cheap enough and runs itself once installed.
