How to make Tiny 600w GrowBox! 28deg

[DrGonz0]

Hi,

This is my first real grow and just wanted to show how I've made a fairly small box hold a steady 28deg temp with a 600w HPS

I have made a stealth(y) box measuring L 90cm x D 42cm x H 89cm it started with X2 130W CFL's but have since upgraded to a 600w Dual Spectrum HPS with a cooltube.

It's has a 125mm Inline Fan, Connected to a 100mm Inline fan, Connected to a 150mm Inline fan cooling the cooltube, this is connected to a passive intake at the top. Separate to this the box has a 100mm Exhaust fan also connected via a Y connector to the 150mm incline fan.

Constructing the Box


Started with this equipment for building the stealth box

- X2 100mm Exhaust Fans
- X2 100mm Duct Vents
- 5m 100mm Ducting
- Cord Desk Blocker Things (lol)
- Random Box of electrics from previous attempt years ago

- 1X Light Shade (Later to be 2)
- 2X 130W CFL's (6400k)
- Mylar or similar style reflective material
- Part of box disassembled

Before putting the box together I decided to cut all the holes a and wrap it in its reflective material first.

After cutting holes in the box for the ventilation (using 100mm holesaw) I then wired up the exhaust fans secured the ventilation over the holes.

I then cut 80mm holes on either side of the top to run the cords for the lights out and filled them with the circle desk things.

I then put the box all back together and it looked something like this closed.

And something like this open (Before I Installed the second 130W CFL)

Planted Seedlings in pots and placed in box

HAHAHA.
I recognize all that stuff you bought. I bought half of it myself.
No wonder bunnings' stock price just shot up.



You have a long, detailed bit of info.
Gimme some time to go over it for you.

Looks good, I'd fix those light leaks though.

 

[DrGonz0]

Thanks guys appreciate the feedback.


Thanks Paul haha spot on the money mate, bunnings loves me! Thanks would appreciate if you could check out my grow as well!

Blac Smoke already onto it - FYI the room it's in is complete black so during its dark hours the plant is still getting complete darkness

Nice cabinet build up how is the fan sound working out for you. And weather striping or using 90 bends works well for light leakage.
