Hello guys first time grower here need a bit of help getting every thing in order looking to buy a 400 watt mars hydro led panel but unsure of the coverage area I will need what size fans and size growtent and best place to vent it I've got a 4 inch hole in my chimney if that would work for extraction wanted to do it in soil wiĺl I need to ph my tap water cus that' all I have ph of 7 could do with some growers love peace

IMO, that LED light is really only good for one decent size plant in a 2x2 or 3x3 tent. Those blurple LEDs don't penetrate the canopy too well and need to stay close to the plant, so you don't get a ton of coverage.

Also, if you use a carbon filter you can just vent into the room outside the tent. No need to pipe the air into the outdoors or anything. A 120+ cfm inline fan would be fine, though it doesn't hurt to go bigger and use a fan speed controller.

And finally, while the ideal pH range for soil is 6.0 - 6.8, I use my tap water at 7.0 for my soil plants all the time, on account of weed induced laziness, and it's never really been a problem. Sure, it's not optimal, and may affect my yield slightly, but I just grow for my head, so I don't stress it. It's only with my hydro buckets that I really stress it.

Also, what are you planning on for nutes and soil?

That sounds like a reasonable set up on the face of it, although I am yet to convert to LED's I am utterly convinced they are the way forward. I think on balance they have a slightly more concentrated coverage compared to their HPS equivalents (in terms of output).

I am currently operating a 600w HPS in a 120cmx120cm indoor tent, carbon filter emits straight into the room. Odourless - but heat is a bit of a nightmare as it is a very modern, well insulated flat. I would only worry about venting up the chimney if you're likely to have heat issues, and then you'll want to ensure you have an exchange of fresh air also coming in from another source.

I would heed the advice of Gentlemenscopse concerning the close range to the canopy.

Can you advise on your soil set up? I'd strongly recommend coco coir over anything peat based, I am sold on it for its draining principles.

I have never ever PH'd tap water or any water - I am probably in the minority but I think PH is a load of old bollocks and only matters if you are running a hydroponic setup. My ladies seem to love the tap water (bombarded with nutes)

Plantmagic soil mate won' it be a smell concern if I vent it in the room was gonna get a 4 inch fan and vent it up my chimney in my bedroom plus I can just leave the vents open in the tent to bring fresh air in wanted to grow some autos am I best start them in the pot I finish in and another thing do I water till I get runoff for the seedlings then water again when pots am light do I keep the lights say about 24 inches from the top of the seedlings was gonna put seeds in paper towes in a Ziploc bag in my tent and cover with a towel just to keep them warm in the dark till I see root then I will put in final pot say 7.5litre when I see break the soil I will then turn light on what light schedule am I supposed to keep them on and what should my temps be and humidiy where should I place thermometer at plant level where they am gonna be what is the probe for on the thermometer where should it be placed

Plantmagic mate with seeds should I just place them in paper towes in Ziploc bags under a towel to keep them warm in the tent till they sprout was gonna do some autos should I start them in the pot I finish in say about 10 litre once seed taproot shows do I put them in the soil and water till I get runoff then water again when pots am light where should I place thermometer and probe what temps and humidiy am I looking for and light schedule I heard they don' need light till they break the soil how close should the light be from seedling I've heard 24 to 30 inches for mars hydro another thing won' smell be come a concern if I vent it in the room mate

So, firstly, more punctuation would help your cause. The stream of consciousness list of questions rattles my brain, especially after a couple blunts.

Most of the answers you are looking for can be found at www.growweedeasy.com which is a great resource. Beyond that a lot of stuff will be best learned through trial and error. I can lend you some insight on a few items though.

A 10l bucket is okay for a smallish auto. Autos can do either a 24/0 or 18/6 light cycle for the whole grow.

And finally, the carbon filter i mentioned above attaches to the exhaust inside the tent and removes the smell.

At the moment I'm using 2 450w leds
Vipaspara 450w and metzi 480 .120cm ×120×200
Using auto seeds 2 to 3 weeks to finish dwc recirc .plants have been topped .

The plants are autos and are beginning to bud I would say 2 to 3 weeks left.
Sorry no way those will be done in 2-3 weeks. Try 8-9 weeks. If you do chop them in 2-3 weeks you will have almost no yield.unless that's a few week old picture.

2 fast 2 vast altho I have messed up and played about with them a bit lst and topped bit of an experiment 3 other grows diffrent farmers have 1 to 2 oz per plant am prepared to take a hit to see if it improves yeild .

These plants are compleated 50 60 days from seed
Well while I think we can all agree that those suggested flowering times are at best guidelines, and at worst horribly inaccurate, and that your plants don't even look close to being 3 weeks from finishing, the really important thing to focus on here is that the thread has been hijacked. Let's see if the OP has any more questions and we can debate when your plants will finish elsewhere.
