Gonna start a new grow and a journal here i have some questions

I am finishing my first grow - bag seed now i think i only have about a month left. I am going to start my first "real" grow after this and i have a few questions so i can figure out exactly what i want to do.

OK so here is the set up I have a 3'x3' grow tent with about 5 feet of vertical grow height.
I have 6 lights - they are CFL spec's below
# Wattage: 105 Watt
# Incandescent Equivalent: 400 Watt
# Initial Lumens: 6,200
Full Spectrum 5000K

I am using a carbon filter for odor control and it works great - i have a 100cfm fan going all the time so airflow is good and temp control is no problem with the compact florescent lights.

I will be doing a soil grow using fox farm nutes soil in 5 gal buckets.

Water is tap water PH adjusted - water sits in jugs with bubblers in them for 48 hours before it touches the plants.

I will be either doing a nirvana blackjack fem seeds grow (if they get here alright) If not i already have fem nirvana Northern Lights seeds.

I plan to use FIM topping on the plants

I would like to get about 8 ounces final weight from this grow (its personal use only so i just need enough to go from grow to grow.

Now to the questions

1) I got the 5000K lights (specs above) to use for both veg and flower and they are working pretty damn well in my opinion but if i were to get these lights for flower how much do you think it would increase my yeild??

# Wattage: 105 Watt
# Incandescent Equivalent: 420 Watt
# Initial Lumens: 7150
Warm White 2700K

2) I know this varies from strain to strain so after putting the plants into flower how much should each of these strands grow? (looking for a rough percentage i.e. 50% of height, or it will double, it will triple ect..)

Nirvana - Northern Lights
Nirvana - Blackjack

3) For getting around 8oz+ dried and cured weight for this grow - how high should i veg the plants? Is bigger better?
(again per strain - Nirvana - Northern Lights / Nirvana - Blackjack)

4) How many plants should i grow? - 4 will fit in there though it will be a tight fit when they get bigger. 3 should fit nicely.

5) Would there be a better way to go then the FIM topping that i am planning on? (I.E no topping, Low stress training, ect.) to get a bigger yield.

6) I am doing the following soil mix potting soil + perlite in equal parts + a little bit of miracle grow moisture control. Can you think a better mix with soils that you can get at lowes or home depot or walmart? (not getting the fox farm soil i got all the nutes and solubles from fox farm).

7) Am i way off way off the mark on my 8 oz target? What would be my probable take with my grow space and equipment?

8. I am going to list the things i cant change but other than that is there anything that i should be doing different?

Space - i only have the one closet i can grow in so the 3' x 3' is fixed.

CFL - HPS and the like would be to hot and i am already using over 600w of power on the lights alone.

Soil Grow - i am doing hydro on my current grow and it just takes to much time to control PH and everything.

Strains - I have already ordered the seeds but if you have suggestions for a new grow i am listening - i like couch lock and a long lasting high - i like the strong stuff

CO2 - don't have the space, not going to do it.

other than those things that is about it.

Anyway in return for answering questions i will +rep and i promise you all a grow journal with pictures when i start.

I would be FLABBERGASTED if you get 8 ounces from a space that small and CFLs. Are you figuring in the size of your pots, the height of the lights and the amount of clearance you'll need in that "five feet" of grow space? because you may actually have more like three.

Just so you know, your 600W of CFL lighting consumes 150% as much electricity as a comparable 400W HPS/MH, while emitting less light.

If we're talking about MH, I bet they produce more heat as well.

I say either aim lower or get a better light. You would easily be able to cool a 400 in there, and it would save you tons of money in the long run. I just don't see that yield being possible with this setup - I'd say 6 ounces MAX, and you'd probably need CO2 to hit even that.

And by the way, I don't know about blackjack but Northern Lights is generally grown outdoors, it spreads a lot and can get quite tall. I think unless you do a ScroG you will run out of vertical space very quickly

Got my blackjack seeds today so i am thinking i will do that one for the grow - i don't want to mix strains if i can help it this time :) Anybody else got any answers for me - all help is appreciated - i may see about doing a 400w HPS i found one and if it will run cool then i may try it. - would a 600w be too hot for a 3x3 foot grow tent? once again i have a always on 100 cfm fan that is pumping air out of the tent (through a carbon filter).

I wouldent use a 600w with your setup, 400w is pushing it! I use a 600w cool tube on a 6" 300cfm and a 4" 200cfm on a carbon filter in a 4'x4' tent and temps are good.

but 100cfm fan through a carbon filter is a LOT less than 100cfm in 3'x3', If you find a way off cooling a 600w in here let me know!
 
Ok so i am thinking i may do a 400w HPS system for flower next grow - as long as you guys think my set up can keep it cool. - +rep to all who have written back so far.
 
Hey guys so i think i am going to do the blackjack for the next grow - i would really like to know how high i should veg them and and should i grow 3 or 4? Please guys i beg you for your wisdom on this.
