Last month it was posted in here for about 420 in Amazon for the same model, it made me to start researching about Green house, have to start building the base and other details, anyone has any recommendations?

Product Description:	There is something very rewarding about growing your own flowers, herbs, or vegetables, and greenhouses provide the ideal environment to make that happen. The Palram - Canopia Hybrid 6' x 14' Greenhouse combines two types of polycarbonate panels to create a balanced environment for your plants. The translucent polycarbonate roof panels have twice the heat retention of single layer panels and allow the light to reach your plants at all angles while the crystal-clear polycarbonate side panels provide over 90% light transmission and block harmful UV rays. Polycarbonate is a virtually unbreakable polymer that provides the light transmission of glass, but is lighter, stronger, and safer. Palram - Canopia engineers their panels and aluminum frames to be strong, highly resistant to harsh weather and sun, and durable. This attention to detail continues with an integrated gutter system for drainage as well as two roof vents and hinged door to provide airflow and allow adjustment of heat, humidity, and ventilation. The 6' x 14' Hybrid Greenhouse comes as a complete kit and can be quickly and easily assembled. Extend the enjoyment of your growing season and protect your plants from harsh weather and pests with the Hybrid Greenhouse kit from Palram - Canopia! Palram - Canopia Hybrid Greenhouse, 6' x 14', Silver: Virtually unbreakable 4 mm twin-wall polycarbonate roof panels block up to 99.9% of UV rays and diffuse sun light eliminating the risk of plant burn Crystal clear polycarbonate side panels provide 90% light transmission Rust resistant aluminum frame extends 6'-10" from floor to peak Kit Includes two adjustable roof vents, rain gutters, lockable hinged door with magnetic catch, aluminum frame, polycarbonate panels and a galvanized steel base Withstands winds up to 56 mph when combined with the Palram - Canopia Nature Series anchor kit and supports snow loads of up to 15.4 lbs. per sq. ft.

Polycarbonate good, aluminum bad. Generally the aluminum frames don't hold up to a handful of moderate windstorms.

Palram's products are usually better than the typical Alibaba/Temu/Better Homes and Gardens (I wish I was joking)/random Amazon brand garbage, but we're still talking about aluminum with parts of the structure only held up by tension.

Pressure treated wood and/or steel, at least for the outer frame, unless you live somewhere with virtually no weather.

Aluminum is a great material for this application. If these aren't holding up it is due to poor design in general, and not the material choice. Aluminum won't rust, and lasts much longer outside than a steel structure (if it is designed well).

I missed the $420-guess I'll wait wasn't buying one until next year anyways.

If you're building it yourself, and milling the aluminum, maybe. But aluminum can be thinned to the point that it's just shy of structural failure, and while Palram's greenhouse structures are not nearly as bad as the cheapest ones, but on the lower end models like this they're... pretty bad. Even if you've got a solid slab foundation (or a good level block foundation around the perimeter) the fit on this is notoriously fiddly, and the aluminum join points will bend, a little at a time, under wind pressure, the vibration of passing trucks or machinery, etc, and eventually, because aluminum is *brittle*, a critical tension element *will* fail. Your weather conditions dictate how long that will take

I reiterate, aluminum is not the material you want for your structural foundation. Too easy to bend, and too brittle where it starts to bend. It's good for the reasons you stated, and in places where you can reinforce it, but you don't want it for pylons, only struts, you don't want cookware that's solid aluminum, and you don't want this aluminum erector set garbage.

I like how the price history clearly shows this has been $429.99 for weeks and today the price INCREASED to $521.05 and ya'll are still upvoting like this is a discount not a price hike. Hilarious.

Yeah, I think you guys are stuck on semantics. Aluminum isn't the problem here, the fact that aluminum is expensive and they're choosing to go with significantly undersized structural components is.
Having said that - I don't know what the alternative is at this price point. I've seen greenhouses made out of wood and poly that are considerably more expensive, and at around this price, plus or minus, I've seen numerous aluminum/poly ones. Don't think I've seen anything with steel, which would be cheap enough to get it done at around this price while not offering the rust resistance.

Ten years ago, you could get a kit with galvanized steel for the outer frame - four corners, across the sides, top beam, and outside of the roof - and aluminum struts (bolted on, not held with tension) for around $600, but the panels were single wall clear vinyl, decidedly less effective for heat retention than these. The galvanized steel had a plastic coating on the exterior facing part, which slowed rust exposure, and I had one of those kits hold up fine for over ten years. It might still be good, I had to move across the country and disassembled it and gave it to a neighbor. The key point was that it had the steel for rigidity in the points that absolutely needed it. I know the prices have gotten competitively lower, and every dollar shaved from production counts, but there's a happy medium, and I really don't think this is it.

I ended up building a frame with pressure treated lumber, liberal application of linseed oil, and parts salvaged from a kit greenhouse that tore apart, leaving only the corners bolted to the foundation, during a dust devil. Enough higher quality double wall polycarbonate to make a 6x14 was $190 a few years ago, but I don't know what it would cost now.
