How close together can plants be?

How close together can MJ plants be? I've been doing LST and previously did some cropping. These white widows are in week 1 day 7 of flower. The one in the upper right can't be LST'd any more for a while as I bent a little too much, taped the joint though, it's holding well. Anyhow, after watering I try to arrange the plants so they get the most light everywhere, but with my 600 watt HPS, there's only so much light. Should they be crammed together more?

Raise the light for more spread...........

Also is the light fixture/reflector perfectly square? If not rotate the light so the longer side of the light matches the longer side of your plant footprint.......

They can be crammed together but you need to make sure you have a lot of airflow so you don't get mildew or insects

Thanks guys -

It's almost square, so no difference there. I've been trying to keep it low for penetration, but these suckers are growing fast in flower. Moving to hydro next and just two plants.

the thing that scares me the most is the ballast on the board on the floor........... and under the light?

put that hot ass ballast on top of the metal cabinet and not that ignition source WOOD and Carpet? no offense just not something I would do especially if you had other humans in your home you cared about. Fire is real

Heres a tip for that ballast bro (i have limited options as well) point a cheap computer fan on the ballast, it will stay nice and cool

Defoliate some - Lose some of those fan leaves - they suck your sugar and reduce your Brix levels - now after that move them a little closer in and your good to go. Week 3 defoliate again - once them big sugar sucker fan leaves come on again and growth is again looking good and like WK1 did; then from WK3 forward you will be good to go and have light focused on fruit and not leave and stem development meanwhile robbing you of your harvest bruh!

I rock 9 plants in a 3 x 3 space 3 gallon coco. 2LBS running blue dream. I prefer plants as close as possible with trained scrog

Wut light you using
I run LED. Can be done with HPS as well but I prefer LED. Highly reccomend a diy build of a COB light. I run 3 COB light bars with 75W using 3 COBS run at .700ma for a total of 225 watts. Before I switched to COB I was running a Mars II 1200 and getting the same results just at 550watts. All about ppfd. I run a commercial strain of blue dream ao your results may be lower but still can pull 1.5 for sure with regular strain in a 3 x 3

It's two fire bricks, actually. Left over bricks from a stove I sold. Angle may be deceptive too, not under the light. Thanks for the concern though!

Thank you. I'll read up again on defoliation, sounds like that will help.

I noticed just tonight when watering that one of the 5 gallon pots had a bit of a root peeking out the bottom. Today is day 3 of week 2 of flowering. I know this could mean another repotting, however I plan to move to hydro on very next grow. Can I leave these in the existing pots, or do they NEED to be transplanted? Would hate to buy new pots and do all that if I won't be using the larger pots again.

That's a good thing! Leave them alone it's all good! Mine are already doing that in my 10gal pots at 1 month old.......

can you get some more reflection? looks like you are losing a lot of light.
I did have that reflective bubble stuff from lowes. Was held on by tape, duck type. Well, I had some extra cfls up at the time too. Found the tape failed, reflective stuff fell on lights and pushed them against a couple plants! Burned a couple sections up really well too. Pissed me off so ripped down the rest of reflective stuff. In doing THAT, the tape that held, ripped off a bunch of drywall. So I then had to spackle a bunch of areas, and once plants are done, paint touch ups.

May try lighter reflective stuff later on, using tacks or something, but for now I'm sour to the concept.
