4x8 or 5x9 Gorilla Tent and Yield?

I have been researching and reading as much as I can on an indoor setup that will bring me close to .5-1lb/plant. With little to no experience indoors, I have run into a problem choosing the size of my tent.

Originally my planned setup was this:
5x5 Gorilla Grow Tent
LEC 630W Sun System Fixture(Air cooled)
8" Hyper fan(stealth) - 710CFM rating
Active Air Carbon FIlter 8"x24" - 750CFM
ThermoFLo SR Ducting
...and accessories like hygrometer, hurricane fan, etc...
6-8 plants in red cups, then 3gal GeoPots, to 7gal Geo, to 10gal Geo.
Using Roots Organics/perlite with supplemental AN nutes - piranha, voodoo, B52, Overdrive, bud igniter, and flush

Now, I am looking into a 4x8 or a 5x9 Gorilla Tent setup with same number of plants, and using 2-LEC 630W fixtures(maybe adding a third later). I like the extra foot on each corner for the 5x9 but get better watt/sqft and lumen/sqft with 4x8.

My apologies for the windy thread, aiming for most information for a more accurate answer.

I have calculated the 630w and don't like the watt/sqft answer in the 5x9. But using the specs from the website with a 4x4 footprint and being compared to 1200w hps = 1- 630W fixture, it looks nice on paper when calculating it as 1200 watts.

So here is my question, would I be able to pull close to 4-5 pounds with a decent veg time, in a 5x9 or 4x8 tent utilizing 2-630w fixture-LEC growing 6-8 plants(gorilla glue, Jock Horror, Headband) Sativa dominant strains, in 7-10 gallon pots in 1 grow?

Which tent size would you recommend for what I am aiming to do???

Thank you for your inputs and advice.

10 feet by 10 feet, and 5000 watts hps. You sound super greedy expecting the results you described.

I have never heard of a single grower saying they have too much space.
With that said... Don't just focus on sq /lumens per watt. that is great that you have got there already but you have one thing that hasn't been mentioned. What training style do you run? Straight loli, sog, a style of scrog?
I run scrog and shoot for a p a plant on my sativa dom plants in a 28x28" screen using a 600w on a rail so yeah It can be done.
So honestly I'd go with a 5x9 tent its in the budget. Worst case scenario you throw in a light rail and call it a day.

more room is always better, work space, etc. same amount of plants, more room is all.
if you were packing every square inch of the floor with plants then calculating every square inch for light would make sense.
you wont get this expected yield your first time around. Temperatures and humidity will scare you, suffer plants, feeding may be difficult as it is for many newbies here. odor is going to be troublesome and when your girl friend breaks up with you......it gets worse.

He said he want 4-5 lbs off 1200 watts, in a small tent with little to no indoor experience...

I would go with the 5x9 and if you want lec then 3 of them. You wont get 4-5 lbs of dank though.

Cookie Master, you are obviously the nae sayer, and the negative energy in this thread. If you have done any research or know good growers. You would understand that 3+ pounds can be pulled from a 4x8 tent with 4 plants. I aim for this goal because I am optimistic(not greedy) and have people that need the medicine. A close friend for example, has had an eye replaced and is with glaucoma. So for you to judge so quickly, and to promote negativity in my thread, only proves you a fool. Keep your comments to yourself, they are not needed here.

I haven't crossed that bridge on training method yet, but have pondered the idea of SCROG, it is something I have looked into. I have also watched a few videos on topping and allowing the plants to grow while supporting the colas with sticks; although it is not recommended because of damage to the root system from what I understand. Thanks for your advice.

...and thanks for answering my question; 5x9 it is.

Proper feeding of the plants has been a strong consideration, from what I understand Sativas have an extremely sensitive root system with nutes, ph changes, and too much nitrogen. I understand that I will have mishaps and will need to fine tune things, but I have set a goal, and will reach that goal...eventually. I plan on setting everything up and running the tent for a few days to try and balance temperature, and humidity prior to starting plants. Figured I would throw a humidifier in there and use the inline fan to equal it out for example(although it prolly won't be too healthy on the carbon filter) Thanks for the input on calculating the light with plants, that puts my mind at ease with these LEC's, I chose them for efficiency and heat(roughly 2200 BTU's per 630 watts).

Cookie Monster was not exactly being negative, more like being realistic. Lets scale this down, most people using a 4x4 tent with a 600 watt lamp are hitting anywhere between a half pound to maybe pound and a half. 8 oz to 24 oz in 4x4. Now saw you have your 4x8 that is still 48 oz or 3 pounds.

What strains do you have, and have you, and when do you want to do this?

Yeah, I realized that after venting, so Cookie Master, my apologies I assure you. I'll be the fool for today. I've been trying to fix the title from 4x4 to 4x8. I currently have the Jock Horror strain from Nirvana, and will be getting a few strains such as Gorilla Glue, and Gorilla Cookies from Elev8 seed bank. I have read really good reviews on them. I am interested in getting going as soon as possible. I grew 5 plants(unknown strains) once to 4' tall in five gallon buckets using a 150watt reptile spot lamp, and bouncing it over each plant from time to time. Unfortunately, the landlord decided to make an appearance, so I had to trash them asap. I have a deep passion for growing the herb I found out. I have given myself a time frame of 5 months after this month to acquire everything for the grow. Right now I am still studying and choosing the equipment during the time of this thread. The only changes will be a 5x9, maybe a 10" hyper fan, and a 1200CFM filter.

so what do you have right now to start?

All I have is 5 seeds, and a $1000. My motivation.

I was undecided and jumped on here to get feedback on the size of tent I needed in regards to a 4x8 or a 5x9.

Amazon prime has a 4x4 gorilla grow tent for about $325 and vortex 6 inch fan for about $150. You have to start somewhere. get another 5x9 tent later.

I know, but the bigger space means I could crawl in there when it comes time to cut them down without risking the smell in the house. What would be the average yield for a 5x5 tent using scrog?

all depends. seach 5x5 tent grows in the search bar.

Thanks for the input, I'll take the 5x5 into consideration, and still debate on the 5x9 for shits and giggles. I'll journal whatever build I decide to go with. It'll take a minute, but I'll get there.

I grow indica's and sativas side by side with the same nutrient and soil and temps and rh and nitrogen too. I dont fuss with the ph in my soil, no need. sativas take longer, veg less here, and typically yield less too. In MI I havent found one patient who actually enjoyed a real sativa since 2008, except myself. led's may leave you wanting, they did me. I'd plant them and let them grow my first time, but thats me.
when I had a grand and five seeds I planted them without fuss after following the guidelines in the jorge cervantes grow bible. I carried those same instructions to a full size outdoor dedicated grow building and have never had a garden issue since. I set it and forget it according to the grow bible, once, no fuss.
I've never employed a humidifier in my mj gardens. I hope you enjoy your sativas.

The only reason I mentioned adding a humidifier to the room was to see if I could regulate humidity getting an idea for fan speed setting. This would be done prior to adding plants to the room, If anything it would be a dehumidifier during the grow if one was needed. I am a fan of the Sativa doms, but have gathered that the Gorilla Glue is mostly sativa in genetics. I have read the grow bible as well, the black&white version, and the version in color(been a while, couldn't reference the exact title/authors). Thanks for the input on Sativas, I have noticed not many individuals prefer Sativa as well. Only the old school bunch that have far more years than I do in terms of age. I have an interest in LED's but they are too expensive for what I can afford to put into it right now.

Skip the Amazon tent, if you are going to be ordering one. I picked up an El cheapo 4x2 off eBay a couple months back. I want to say it was like $60 some bucks shipped to my door. Took five minutes to assemble and it seems built to last; metal corners, multiple support brackets. It might be worth a look on eBay to find your tent. I ordered my reflector off of there too, the cheapest cool tube available, and I was not impressed. Ended up breaking the cool tube and ripped the reflective aluminum out to make my own wing.

If you do end up going through Amazon, watch out for this scum fucker named "Low_Baller". That hack job couldn't pack a bowl, let alone a package for shipment. He packed my last ballast and reflector combo with the cord for the lamp right over a the top bracket of the reflector, so when whatever it was that landed on top of my box landed on it, it sliced my cord nearly in half. Luckily, I had another one I could replace it with. Also, that hairy turd will package up used lights, and send them to you instead of new ones when it says "new bulbs" in the listing.

Guy is probably the feds, hoping to disrupt growers

Edit: just noticed that the thread it titled "Gorilla Tent". If you have your heart set on the name brand, go for it, but I think one of these cheaper ones can still get the job done. The only "qualm" I have with my tent is that it is not 100% light tight, but since it's a veg tent it doesnt matter. It could be made light tight in a matter of minutes though. Up to you, man, but I'm always looking to save some money.

Unrealistic goals for a, self proclaimed, inexperienced grower. Start with a 5x5, get your shit down, then get another 5x5 and duplicate the first one. It's WAYYYYYY easier to get consistent 1.5-2# per tent, than try to max out yield every time. As you get more experience, your yields will go up.

Plus, running 2 tents on overlapping cycles, say 4 wks apart, makes harvesting a little less intensive. Trim 1-2lbs every 4 weeks, or 3-4lbs every 8 wks?
