80cmx80cmx160cm (2.6x5)

Hello,
Im recently New to the grow tent bussines as i always grown outdoor. But now i had to buy a kit tent. It comes with 400w hps with pure light open ballast, an intractor 107m3/h, can-lite 150 carbon filter, extractor 145-187m3/h, is this enough? And this grow tent doesnt have wiring hole. I was thinking about plugin it on the wall above the tent along with the ballast (is it ok to hangbit dirrectly to the concreto wall? . Is it ok if i pull the wiring thru the extraction holes togheter with the aluminium extensor? Any sugestions how i should build this? Tha k you all and sorry for all the questions

Yeah feed your wiring through your duct sock and then pull your duct through afterwards.
Just make sure the connections (male/female sockets) have no chance of been pulled out.
They need to be 100% connected.

You can hang your ballast on the wall. Just make sure whatever you hang it on is well secured. Drilled and plugged properly.

As for the fan 100m3/h is not a lot, but it will depend on how cold or hot your environment is.
I have a silent fan which is about 120m3/h and it keeps my 1mx1m tent in the right range all year.
Everyone's environment is different.

If you can post a link to the kit it would help.
