600w cool tube setup help..

Okay so I've got a 80x80x160 grow tent with 5" cool tube 5" fan and a 5 " ram carbon filter all will be one set up. Carbon filter>ducting>cool tube>about a foot of ducting outside the tent to a 5" fan pulling air from the tent creating negative pressure..using the passive intake vent.. btw the tent is in a brick shed with a 13a extension up to 3000w unwound. . And a 6a for the fan on separate extensions from the house which is hidden... and fully waterproof.. the 13a will be use to power a 600w hps.. ive tested the lamp and ran for 10 or so minutes... and fine...just wondering would a 600w be too powerful for small amount of space.. I have a spare 4 " fan just in case it gets too hot.. my seedlings are on day one they are feminised fast and vast auto flowers under a 200w cfl for 18/6 for about two week then going under the hps. I know there supposed to be under more light when flowering but can I get away doing 12/12 also going straight into there last pots as they don't like to be transferred to other pots..nutes ill be using is bio grow and bio bloom.. as my soil I have coco bricks... this is my first post... also can post pics..

That 600 will heat it up quite a bit even with cooltube depends how cold ya intake air is

400 hps max or get a 1.2 1.2 2.0 tent then ya good

Can easy change to a 400w have a few new bulbs..

Well it is a cool shed.. the fan is pointing to the door as the passive intake is about a foot away from the cool bricks

Are you on a digital ballast were u can change setting?

Just try it n check temps but ya need atleast a 1 foot gap between ya light n plant then there's pots don't leave much room for bud.
Check out scrog or lst this will help u in a small place

No bud have a 600 and a 400.. but will be investing in a lumi 600w dimmable digital ballast soon..

Done 2 plants with a 400 got about 2 off each.. which was my first hps grow..but ive got 5 seedling ive checked space with the pots and there more than enough about quater of a foot between each and there 10 litre.. would a 400 do 5?

Not in that space I think it would get overcrowded

I've seen tents jam packed just sure I could as long as am pruning??

Some autos can get pretty big cramming 5 them in less than a square meter is asking for trouble that's all
