@Gpaw I’m glad you asked about the LED’s because it got me really thinking about the finer details of how I’m going go wire it.
What I’m thinking is this
The 3 supplies are 200w each. I’m going two parallel strings of 12 for a total of 24 on 2 supplies and 3 strings for 36 strips on 1. This lets me put 36 total on the ceiling and 48 on the walls. The 12 strips on the walls that are sharing a power supply with the ceiling strips will be on a switch.
This switch will allow me to turn off the 12 strips on the walls running at 8.3w. The remaining string on that supply will get fed 16.7w each strip and that will shift the wattage balance to 400w ceiling and 200w walls like this
My line of thinking for the switch is this. Of the 48 on the walls these 12 are the hottest. So if any are going to go below the scrog net its going to be them since the plants will never reach that far to get potentially burnt. On top of that once I’ve flipped the lights to 12/12 I lollipop below the net line which means there is no point running those lights anymore and i can turn them off and use the wattage where it is more useful.
This also leaves other options available to me in future. For example if at a later date I don’t want 100% 4K’s on the ceiling I can easily put those lower 12 on their own separate switched power supply and mix in 12 or more 3k in their place on the ceiling since there will be plenty of room. I should be able to squeeze a total of around 50 side by side on the ceiling depending on how i cut the aluminum plate and how i space out the 4k’s when i install them.
Hope that’s clear as mud and thick as water for everyone and I’m looking forward to see how well it works in practice once I get it all installed. It’s been cold as shit the last couple days and I haven’t wanted to piss around digging out the plate from the shed and cutting it to size outside.
