Starting to grow

Hi..so i finally decided to try and start to grow my own weed. I searched a lot over forums but i still have some questions if you dont mind to help

So this is what i have:
DIY Growbox (Height-92 x Width-45 x Depth-61 cm), 150 w HPS light with reflector and 4 computer fans 120mm

Would 4 computer fans be enough to deal with the temperatures? I was thinking about putting 3 of them for exhaust and one for intake, and maybe i would also cut one hole for passive intake.

I was also thinking if it would be smart to put plexiglass between HPS and flowers? It would create some kind of a chamber with hot air at the top and i would put one fan for exhaust at the top.

Any ideas welcome

yeah you basically could build a little makeshift cooltube like that i suppose i would put pc fans just for cooling and extracting your light. then you can have a passive or active intake on the bottom for the plants along with the exhaust also. what are you going to do about smell? thats something you should be planning ahead for because a small box can stink up your entire house.

I am probably going to buy another fan so i can mount carbon filter on it. How many flowers would you advise me to have? Should i have lowriders because of low height? Or should i have some normal plants and SCROG them?

I would also recommend a small oscillating fan or 2 for enhanced circulation and strengthening your stems. Also helps prevent mold and fungus. Other than that, sounds pretty good. Best of luck to you. Happy growing.

i would check out some of those PC grows 3 feet isnt alot of room your light is going to take up a foot so yeh maybe screen it or lst them to keep them short and go with autos or 12/12 from seed

First of all thank you for your advices. Now i have another question. Is it possible to see if this is a male or female plant?

the gender is not clear yet, but pic 2 does seems to be looking a bit manish, but this not for sure

just keep a close eye on them, won't be long before the gender is obvious
