When I was using those same pots, some of mine had to be watered a second time because they were getting too dry for my liking by the next morning with just coco, no perlite.
But that’s just my personal environment and I use 1200 watts of high pressure sodium in a 4x6 tent so it might be different with the leds your using.
I just started using leds in veg and had to raise the feed levels because they weren’t drinking as much as they did under metal-halide lighting.
Less heat=less they transpire.
You mentioned under or over watering being a concern so you made a great choice choosing coco. As long as you have good drainage and your plants have some roots you can’t over water coco. The more the better to a point. Each watering bring fresh oxygen and nutrients and washes away the old stuff.
I would recommend a good digital EC/PH meter if your serious about growing too. I love my blue labs combo meter but there are lots of choices.
Once you get growing and start researching more you’ll figure out what you want to do and refine different parts of your setup as you go.
What did you pick for seeds for your first grow?
