Theses are auto flowers so I shoot fif as little stress as possible . I water the media ahead of time then measured amounts of water only until 3-4 nodes then I water to runoff
Don't be afraid of autoflowers.
yes you don't want to stress them but you don't really want to stress any plant
you're going to likely stress them more trying to keep them watered properly then you would have by starting them in a smaller container
When I started growing again few years they gave me my 1st ever autoflowers for free and before I had read all the hype and the do's and don'ts I treated them just like photo period plants and they grew pretty much the same way too
I topped & transplanted them right along with the other plants they didn't really grow any differently except for the autoflowering bit, they grew under 12/12 and they gave me close to the same yield as the photo plants too
