Hello there r/Microgrowery,using a trhowaway for reasons.

I've been reading the sub and other pages for a while,excited to start my first grow/setup. Important to know: I live in an illegal country, not much space, the tent will be in a closet.

Setup:

• Tent: 40cm x 40cm x 120cm = 1.6'x1.6'x4' Secret Jardin HS40
• Lights: 132W±3% real wattage Viparspectra V300
• Fans : 105 m3/h= 61 CFM Vents VKO100 and a small clippable fan
• Carbon Filter: 150 m³h=88 CFM Can Lite 1500-plastic
• Nutrients: VitaLink calmag, General Hydrophonics TRIPACK FLORA
• Growing medium: Buffed Coco with perlite
• Pot: Regular 5 gal (couldn't find smartpots were i live)

My questions:- Is this type of cheap fan enough and how hard is it to install?
- Can i do the Coco buffing with this type of calmag?

So this is it. I should add: I will be growing Royal Critical Automatic seeds from RQS(starting with two,keeping only one in the tent). Any advise or citique is more than welcome, thank you in advance.
