COMPLETELY NEW HERE.. need suggestions and advice.......

New here, so suggestions and constructive criticism are appreciated.

I am to set up a pretty small closet. Right around 7.2² ft.
approx. 3.6ft x 2ft x 8ft..

I am to start with a digital ballast 600w w/ MH & HPS combo with the 6" cool tube ran with an inline fan running/exhausting straight out at the top or the ceiling.
(Mh for veg and HPS for flower)

-I need suggestions on fresh air techniques and adequate heat and odor ventilation.. new to HID and that whole scene-

(Not really worried about cutting holes in drywall or anything, those are simple repairs)
PLANS..
-Cutting a 6"hole in the wall towards the bottom to run a 6" fresh air line. (suggestions)
-Thinking about pulling the fresh air from outside of the closet from the bedroom the closet is located in.
-Would this work? right?.. It will be cooler in the room then outside in summer. I'm thinking of having a inline fan(if req)to push air in. But I have heard this is not mandatory as it will already suck air in..? so do I need to push air into the room or just create a 6" or 8"line towards the bottom and run through the wall and to the inside of the closet.
I have seen fans hooked up on the outside pumping air into a 6" line going to the room too.. so whats your take on this?

Ventilation

-Also an exhaust 6" hole cut at the top corner of the wall or into the ceiling
- with a 470cfm rated carbon filter mounted in the highest and out of the way spot
-with a 400cfm inline fan pulling air through the carbon filter/air scrubber and exhausting the odor free air out most likely into the bedroom ? Or should it go out to the attic? Exhausting it out of a window is not really an option.

-Exhausting air from carbon filter up to the attic vs back into the bedroom (suggestions from your knowledge or experience and or your opinions..)
I have heard of causing mold with the attic but I don't think i'd have to worry about that too much about mold as it has a few different places to open the attic and let breathe around the house.. which is better though.. routing the carbon filtered air being pulled through from the inline fan and out through a 6" hole in the top of the wall and back into the bedroom or going to the attic..
-Leaning towards the routing it through back into the bedroom as house is fully air conditioned in the summer and I could leave the door open on the bedroom for more air and leave the door open on the grow room during lights on for even more air or at least open it for a few hours a day.
But I am more worried about when flower time rolls around and having all the ventilation and everything perfect as I do not want any light interrupting my beauties sleepand I know they need a lot of fresh air so whats the best technique for thus getting fresh air into the room ..
I know fresh air should come from the bottom so it will be cooler and then exhaust the hot air from the top of the room with a carbon filter and fan back into the bedroom. Any problems with that? I could even put a vent cover over the holes in the bedroom and make them look as normal as possible or appear as if registers. But i am not too concerned with appearance and the privacy issue. I do not really have any privacy concerns besides odor really for that matter. (FYI)

So exhausting the hot air from the top of the room through a carbon filter and inline fan sucking air through the air scrubber and blowing it back into the bedroom.
Fresh air running from the outside of the closet through 6"hole hooked up to another inline fan. Maybe adjoining the fan so that the fresh air and the lights cool tube is together, separated by a Y connection splitting them off. One going to the bottom hole for the fresh air. Pumping in air and one to the upper hole for the light cool tube then back out exhausting into the bedroom

Here is my thoughts... since I am going to run a 6" cool tube for the light and have air coming from the bedroom from a inline fan at about 400-720cfm (6"=400cfm or 8"=720cfm)..Could I just split off of this cool tube air line and make it have another 6" hose running the fresh air into the bottom.. using like a Y connector to split it off the line from the air pump.. One connection going to upwards to the upper 6"hole for the cool tube 600w MH and HPS. and the other 6"hose running into the lower bottom 6" hole, pumping cool fresh air from the bedroom inline air pump. (Any problems with this idea?)
(only issues I see is that I will have to always cool the light too and cannot pump air in just by itself but that would not really matter to me as I will keep the light on 20/0 hrs - 24/0 hrs for VEG anyway. So it will need cooled, But flower time it will just run 12 hours for really no point but that is really no big deal at all to me. Not a huge concern. But Do you think a Y split connection would work good for fresh air flow? ..
21UVC1n+hwL._SL500_SS100_.jpgI am thinking using the hydrofarm active air 8" inline fan rated at 720cfm to pump air through the light's cool tube line and out and also to pump the fresh air into the closet through the bottom hole ran from a separate line off the Y through the wall from the bedroom. I'm thinking just having the inline fan hooked up on the outside of the closet and installing some sort of a Y connector to it
If I use the 8" I will have to bottleneck it down to 6" to fit the cool tube I was planning for, or I could just find a 600w with 8inch cool tube possibly. Idk
Maybe when I find a Y connector they will have one that goes from an 8" hose down to two 6 inches. Its possible, but Any way whats your suggestions on pumping fresh air in and exhausting and all this. I'm new to all this HID and heat and ventilation and everything.
I know all the basic stuff though and have had a few runs(CFL)before but now I want to have some real dank medicinal.. and I know there are plenty experts on here so I could use the advice and some pointers. Thanks

plans..

$160 on amazon (great start, good product reviews)

51xkHlIdV9L._SL500_AA300_.jpg-Digital ballast 600w MH & HPS with both bulbs they just switch right out with one another.
I am going 600w because of the small area+less heat and because you can get it closer to the plant and therefore the plant getting more lumens + can also build on and add more later but right now focusing on right now and going with what budget can allow.
-What seed bank do you prefer and have had good experience with ?.. which ones would you stay away from..
I'm thinking of getting some feminized pineapple chunk and some feminized LSD. any suggestions
ceiling is 8' and with the air tubed light and carbon filter and inline fan all installed inside I do not think I will want anything getting much over 5' or much close to 6' for tops
( I want a decent yielding quantity bud and exceptional dank quality) (Personal medicinal USE ONLY)
not to sale!
-Mylar to cover all walls
-Thinking of adding some extra CFL lighting mounted on the walls. I have a few cabinet sized 75w output grow purpose CFLs left over from a few years ago .. maybe 2 or 3 on each wall to support healthy side and steam growth and developments along with the blazing 600w MH & HPS mini sun lol.
-Fox farm ocean forest soil- has 30 days worth of nutes then I have seen some peoples suggestions say to not use any more until last week?
(is this the best soil) what is the best soil if you think it is not and maybe tell me why you believe the way you do
(no budget for hydroponic at this time, maybe next time)
So unsure on the nutes. So suggestions.. heard good things and bad things and everything in-between lol
soiltabs-10-tablets.jpgflowertabs-10-tablets.jpgvs61oaXp+ordL._SX450_.jpgSoiltabs and flowertabs ? vs Fox farm nutes ? (big bloom, grow big and tiger bloom)

I have heard not using any nutes until the last week of flowering and I have seen people use them all the way through..
What do you think? Which is better ? What were your results

-Reverse osmosis water or distilled water ? prob R-0 right

-0₂ ? what is your experience with it, how should it be used / should I use it...

figuring
probably max of 6 plants at once in the small space. Probably go with like 5 for starters. Probably as many pots as will fit lol
all feminized seeds(atleast as of right now) I don't want to waste any time or space with the males. I dont swing that way lol
about 2+months for veg
about 2+months for flower (what ever the strain recommends)
Thinking that while I am flowering I will eventually get another 600w ballast or another whole setup for the MH that is not in use and veg with it in separate area so that when the others are done flowering, I can just put the newly veg'd young-ins in the place of them under the HPS under the 12/12 cycle and keep harvesting like that about every 2 months and repeating the process with different strains and so forth.

Basically from your perspective, what would you do if it was you. I want to make sure everything is right . I am planing to get started very soon and I do not want to mess anything up. I want to run through as perfect as possible. Help is greatly appreciated

I find my plants dont grow As big As they would when i start clone or seed in those Pod things
I say 2 pints / solo Cup Size ~ & no Smaller ~ Just my Pref.
both lights will Grow That Size of area 7.2 sq ft
600watt 3x3- 9sq ft
1000watt 4x4- 12sq ft
As for Light warrior ~ never used it. ~ I alway by FF Ocen Forest Mix Then mix W/ Something Cheaper ~ My Fav ~ BlackGold

Also 1000 is going to go deeper into your plants then a 600 ~ it is hotter & cant get AS close But 1000's R were its At
If You have a Vented hood W/ Glass Between the bulb & Plant ~ you cant Get Pretty Close ( Closer When Vented )
But I have had any issue Before Where I didnt feel like My 1000's wernt Close enought ~
I suggest 600watts for Hanging ~ No Hoods
I use a 600 to get the popcorn Nugs Nice & Chuny Like the tops ~ i Hang down like a Vertical Grow

R you going to have 2 rooms Grow & Bud? Or just One Room & Switch out Bulbs?
I suggest Having a Designated 8x8 BLOOM Room Give you some Space to Move around Plants&
5x5 grow area ~ This Will Help keep The nugs Flowing ~ As you can throw a New Plant in every time you harvest One




And Last but not least ~ Nuts ~ i would Start 1/4 or 1/2 dose
Every Strain is gonna React little Diffrent to The nuts ~ So it finding the Stain that work well in your Nuts & growing conditions.
MAINLY TRIAL & ERROR! ANy Whoot GL hope to see some photos when ur done
