Lighting please help noob with 2 x p900 in 6' x 6'

[Dan2234]

Hey guys!
Noob here first time growing I have some questions about how to do my first grow!
your help is much appreciated!

here is my Setup:
tent: 6 x 6
lights: 2 x platinum LED p900
ventilation: 2x hyperfan 6 inch for intake and exhaust

soil recipe for seedling:
just happy frog

soil recipe for after transplant:
2 part ocean forest
2 part happy frog
1 part perlite

strains: all autos around 7-9 week flowering time.
light schedule: 16/8
training plan: only bend and secure maybe super cropping

Questions:
1- I am limited to 4 plants legally. I want to get the max harvest per unit of time. I can't do a sea of green with a lot of little plants. with this in mind, what pot size should I use for maximum plant yield?

2- should I be starting the plants with only veg switch and then give them bloom + veg after some time or do I start full blast day 1?

Thanks!

You have a huge space. I would go with 5 or 7 gallon pots. And with autos they are going to auto flower no matter what but you could run in veg only in an attempt to get the most out of them. What strains do you have?

Thanks for your reply!
I know they are gonna autoflower no matter what but since I'm running so much light power I am worried about killing little plant with too intense of a light.
as for strains, I got my seeds from crop king seeds in Canada.

Great strains. Keep your lights at least 30 inches away and you should be fine.

thank you! keep the lamps 30 inches away only when they are little plants? how close is safe when they are budding?

will do sir!

I would never allow those lamps closer then 24 inches ever. They are powerful lamps. You will burn your plants.

Great advice @Ripper. The P900s are definitely intense lights, so stay in-tuned to your plants, if the show any sign of light stress move the P900 up a couple inches until they bounce back.

Looking forward to following your grow!
