Some say you can't overwater a well-drained potted plant, some say you can. Some say leave it a few days between watering, some say water every day and then every 4-5 days don't water for 24 hours.
I'm slowly getting my head around it by just watching and learning from my little seedlings and my rehab project plant that I adopted a month ago.
I've gathered by not watering constantly, the roots grow, searching for water which in turn means more growth above the soil because the root system is bigger.
Figuring there's variables with watering due to day temps, medium, pots and... everything, so I'm hoping I can get some more tailored advice.
I'm growing some autoflowers (White Widow, Lowryder, and some mysteries). I started them out in jiffy peat pots with peat pellet soil. Once they were above ground and going well, I moved them to some small plastic pots I had laying around (removed peat pot). Would have preferred to put them into their final rhizo fabric pots but there was a delay in my order getting to me, so... ya make do.
Rhizo pots arrived on Sunday. Got my act together and transplanted the first one I started (WW) into the rhizo this morning. Hadn't watered since Sunday, so I could try and make sure once the trasplant happened, it'd be a good thing for her instead of a stressful thing.
Slowly but surely over this week, I intend on moving them from their plastic starters and into a rhizo pot each where they will stay and nature can take it's course. Pots are 12L. My soil mix is a fairly even mix of peat moss/perlite/compost mix. So I have the moisture retention in the peat moss and aeration of the perlite plus the organic goodness of a compost mix that includes coco coir, compost, manure teas, worm teas, castings and other stuff including beneficial bacteria.
What should my watering schedule look like? I'm probably way overthinking it and I'll learn on my own through trial and error but just want an idea from people that know their stuff. I've also been adding a very small amount of worm tea and seasol once a week to their water.
Dog is going blind and I can't have the pots out in the yard because she knocks them over not being able to see them, sometimes. They're up on a deck that gets full sun from 9am until sunset and it gets quite warm up there. Two weeks ago, I was distracted for a day where it got to 41° and my big plant and clone I was given got heat stress from being out in the heat in black plastic pots. Clone is still recovering but big one has sorted herself well after a bit of TLC and also adding seasol and worm tea in her water.
Plants are under 24 hour lights at the moment. Sunshine with supplemental light at night in the form of a 130W CFL in a reflector.
So, should I water every day in smaller amounts then let them dry for 24hrs every 4-5 days or water until run off and drench the pot then wait a few days between watering?
Sorry for the novel, just want to learn as much as I can during my first run so I know more next grow.
Here's a picture of them from today. WW is 10 days since popping her head up and the others range from 5-8 days since emerging. Still early.

While I've got you here, I want to mulch the top of my pots to feed the microbes and protect the top of the pot from drying out. The sun here is pretty intense and anything of a darker colour absorbs quite a bit of heat. Going to Bunnings tomorrow and want to get a good green and brown mulch for them. Any reccomendations?
