INPUT NEEDED - First attempt @ stealth grow fridge

G'day guys - New member here.
Just after any tips / feeback etc.
Haven't grown in a long time, and things have come along way with LED growlights and what not now.

As a constant sufferer of migraines I thought it was time to grow for my own use again.

Setup is as follows
An old fridge/freezer hollowed out and sealed up - about 1.6mtr tall and around 2ftx2ft floor area.
I sprayed all the walls with a satin white paint to help with reflectivity too.
4" intake fan
4" exhaust fan with a carbon filter attached
300w viparspectra v300 growlight (read that it was good for 2ft x 2ft) and to save $$ only consuming 136w - Running on a 20/4 cycle
Have the growlight on a pulley system.

Is what i have in there enough lighting etc?

I have no local hydroponic shops but am considering switching to a hydro growrocks grow with the next grow, I wanted to go as chemical free as possible so at the moment ive been using a rose mix with some perlite & applied some seasol spray during veg and a little during the start of flowering and some worm castings..

Plant on the left is a Berry bomb auto flower (i lost track of when i started it but i think its about 8-9 weeks from germination now?)
On the right is white widow which went in a couple of weeks ago.

Basically all im after is any info that will help me produce more buds? i didnt bother training as these where autoflowers and i wasn't sure just how big they grew as its my first time with auto flowers.

Is there anything that I'm doing wrong that can be corrected?

The next plants to go in will just be another lot of autoflowers i have, and then some Fem seeds so i can scrog in there and hopefully increase yeild.

How far off do you think the berry bomb is off harvest? I'm hoping to do a staggered harvest to try to increase yeild.

anyways heres the pics.
Thanks in advance

More/better light. White light to be more specific. With that consuming 136 at the wall, a quantum board 135 watt will likely blow it out of the water. Whats the air quality of the room its in? If the air movement through venting will keep the grow cool enough you could probably push 2 90 watt quantum boards and really increase output.

Ace ta.
air quality in room is good. Room has a constant window open too so fresh air always coming in and its winter here at the moment too.

I'm considering switching to a 80cmx80cmx160cm tent and throwing a 600w viparspectra in there? would that be suitable/a better job?

I was leaning towards getting away from the viparspectra/mars cheaper led setups. You could probably get better output using "60" watt cree household bulbs. The 40 watt ones are considerably cheaper but dont compete with the output/efficiency of the 60 watt units. A diy cob or quantum board build would be ideal though. Just about double your photon output with the same wattage draw and have a better/more complete spectrum.

My issue is I'm in regional Australia.
Hard to get that stuff around here

Will look into the DIY quantum boards for sure tho

Dude, cutter electronics! And i believe northern growlights will ship to oz? They make the quantum board

northern growlights is now hlg (horticulture lighting group) sells the quantum boards
https://horticulturelightinggroup.com/collections/diy
they are in big demand and you need to be fast when they become available cause they sell quick
ask robin or stephen there any questions you may have
from what I know in a 2x2 area 1 quantum board will be enough for that space get one in a 3000k or 3500k spectrum and you can use in veg and flower
