cab vs tent question

[babiesoftus]

I made my own grow cab but the ambient temperature is at 30 celcius and temps inside the cab could range around 30-35 celcius. (growing in led)

i have given up on trying to manage my cab because the weather here is just too hot (i live in a tropical place) and using an ac is just out of the question for me (budget issues)

my friend told me that my temps would be so much better if i bought a grow tent because the insides are lined with mylar, etc.

i was wondering if this was true. any thoughts? im considering buying a tent just to avoid high temps lol.

How big is your grow cab, your fans and your light?

How big is your grow cab, your fans and your light?

it's about 1.8x2x6

i have an 6 inch exhaust, 3x passive intake at the bottom and a 4 inch oscillating fan.

i was thinking of getting a growtent from your site and stuck between sj dr90 2.5 and the one from growlab 2.7x2.7xsumthin

my light is a 200w(155w) led light from china.

also, i was wondering if ducting is necessary for grow tents? will it be possible to just install a 6-inch exhaust fan at the port and it won't be screwed up while i use passive for my intake
