chasv77answered grow question 5 years ago It all depends on what size and type pot you will wind up using.
I wont comment on when it is a seedling and what temporary container you are using.
When you transfer you seedling into its permanent pot (gal size?), water sparingly (one US qt.) around the seedling so you don't collapse the soil around it, before it can really take root. Stick your finger into the soil to around your second knuckle to see if it needs more watering.
Once it is in a few weeks of veg, you should increase water delivery to you see it coming out from the bottom or sides( if fabric pots).
For example: I use three gallon fabric pots in a grow box. I will use a whole gallon of water or water/nutes, pretty much every three days on each pot. It is just enough to run out the bottom/sides to reduce any accumulated salts or other brine from the soil. This is a dialed in process and works every time, as long as the temperatures are kept within the proper range.
GOOD LUCK
