My proposed grow. Couple questions and looking for some input

I want to start by saying thank you to the rollitup community. Ive learned a lot over the past couple years from you folks here and the knowledge is invaluable. This is only my 4th grow but all the ones before it weren't even given a real chance, lack of money and time.


Without getting too technical, what I'm thinking is...

• 12 plants - 6 x RD Ghost Train Haze#1, 6 x DNA Kosher Tangie
  
• 5 x 10 grow tent
• Running soil - ffof with some guano, worm castings and perlite
  
• Advance Nutes expert line - Im still so new to it I just want something that will work, until i get more hands on practice with growing. As i said, ive read alot but... "in theory there's no difference between theory and practice, in practice there is"
• 2 x 1000w - possibly a third... full ventilation. already going with overkill on it probably
• Dehumidifier - if needed in the tent

I was thinking about doing a 2-3 month Veg with serious LSTing and some topping. Would flower for about 11 weeks after that.

Questions-

1. what about adding a third 1000w to the mix?
2. Co2 is an option. what about just using my fermenter? i usually have a batch running and i can get it to hit 2300ppm stable. just change the airflow some and can keep it pretty much around 1500ppm. I worry about the smell messing with the bud smell

Well I'd really appreciate some input, i didn't want to get to long winded but i can provide any other information.

--Thank You--

3KW for 50sq ft isn't unreasonable. From what I've read 50W/sq ft is about nominal.

Just my opinion, maybe a 600W for third light, and during veg you run the 2 X 2KW MH and the 600W HPS for a fuller spectrum. During flower it'd be 2 X 2K HPS and 1 600W MH

You got the cool tubes, filter and fans, right?

Unless your 12 plants are going to very horizontal your not going to take full advantage of 3 hoods.

If you want to increase the watts/weight in get hoods that hold 2-1000 watt lights and have 2000 watts on the same footprint you were going to have 1k. (4k total) Your colas will be the size of your forearm.

You want green under every sq inch of the footprint. Then if everything else is going right you will yield an average of 1-2 grams per watt.
That could be with one plant or 10 under the same light, its all about the coverage. (and of course veg time)

Also remember flower your plants with 2x the power you veg them with.

co2 is if ur under very tight room conditions man, not for a home grower imo
