Hey Guys hope you all having a great time.

I have a question about the Mylar fabric, Is it good material on preventing the temp inside the grow tent from getting too low even if it 68~50F degree outside?

Which one is better insulation Mylar or Aluminum insulation film(double layer 6mm thickness) like the one in the attached photo?

Finally Should i get ready made Tent about $60 or make my own for $20~30??

Also please consider that the tent size will be about 80x80x160cm and i will be using 400Watt HID
Average Temp in my area around: (Nov: 68~64F, Dec: 64~55.4F, Jan and feb: 50F or below)
Thanks
