I'm trying for a 3 week perpetual setup,
I have a 4.5 square, and a 3.5square,
2 600w and a square t5 bank

I'm hoping to pull 10-20 oz a cycle
with 5 weeks from seed, then 9 weeks of flower

my question is , would I be better off running the seedlings under the t5, begging under 600, then flowering under the other 600,

or or vegging under t5, and flowering under 2 600 watt lights, and using co2 if needed to boost yields

i am looking at doing 12 plants per 3 week cycle,
so 36 plants in the 4.5

this is only my third grow, so advise is more than appreciated.

Very true friend,

I just want to make this work from the start

It doesn't take much light for the cannabis plant to reach a mature vegative state. I would use the bank of T'5 and than the 600's when you change their light cycle.

How big is your area? How many plants are you planning? Are you going to top or let them grow tall?

I have a 5X5 and a 4x4, the 5x5 is 25 square and I am lucky to get 10 ladies in there.

In my 4.5 square tent
I have 12 semi bushy ladies flowering with enough room to stand inside

I think you'll find that you'll want to find a strain and phenotype you like and keep a mother to take clones from. Running seeds in a perpetual is a guessing game you will have no control.
I run a 2 week perpetual with 2 plants in 2 1/2 gallons of coco dtw under a single 600 for flower. Rooted uttings go under t-8s for three weeks then under a 250mh for 2 week then in to the flower room they go. I am pulling 1/2 lb. every 2 weeks with this setup.

Would 2 600 lights in cooltubes be to much for a 4'6" square tent?

not if you keep the heat under control.

Would I need co2 to maximize yield

The amount of light you have is a big factor in yield.

All depends on your budget and the ventilation system in place.

Alright, I moved my 2nd 600 watt into my 4.5 ft tent, but I left the vegging bulb in there as I had read that ideally you would get better performance from having both -If- you were able, and since I was....
But I wanted to ask if that was a correct understanding.
I cannot run co2 atm due to the amount of heat generated by the lights
those things even in cool tubes are posing a bit of a problem.
But I figured that 2 600's in a 4.5 with 17 plants should give good yield.
Advice would be appreciated.
Thanks
