What the optimum amount of HPS Lighting for my GrowBox?

I am starting small Grow with 1 AI plant in a 2'x3' GrowBox.
I plan to Veg using a few 6500k CFL's.
But for Flower, I think HPS would give me better yield.
So with my sized GrowBox, how many watts HPS should I use?
Thanx! :leaf:

well id go with a 250 with coolshade with 5inch extraction and 4inch intake if you want the temps to be even lower go with 6inch extraction and stick with 4inch input if the 6 makes it too cool you can always buy a fan controller and lower the speed and itll also make less noise

sorry didnt see the height might go with 150 3ft dont give you alot of room unless your gonna train it how tall is your plant now ?

if i only had 3 ft of room id go with cfls and t5s cfls can get in close for side lighting and less heat

well remember some plants double or triple in size once they are put in to flower if you only got 3 feet to the top of your box youll need to flower it when its like 10inches tall to give you space from your light final size would be 30inches give or take if it triples in size

id have a look into lst might give you more room to work with and a better yield

Look into SCROG. A 250w HPS would work with a 4" fan for heat exhaust. Also, you probably are gonna want to have your carbon filter outside your grow box due to space constraints. That is if you are planning on dealing with the smell.

That smell is not my concern yet. I'll cross that bridge when the issue presents itself.
Right-now, I just wanna get the best yield I can from one Indica plant.

It's a stealth closet grow.
I could theoretically make it up to 6' tall, but the smaller, the more stealthy, the better!
My near term goal is personal stash, but if it goes-well, I'd like to scale-up to provide for dispensaries.
I have two empty bedrooms for scaling-up!

well make it a bit taller so you have some head room and go with a 250 last thing you want is your plant to be stuck against your light also it gives you room for the carbon filter when you need it
