Average is every 3 days. My seedlings I spray with water daily so they don’t dry out but once they are past the seedling stage (about 2weeks) go for every 3 days. I use a moisture detector but I can usually just tell.
I actually poke my finger in the soil to see if it needs water.. too much water and it can drown, you end up with gnats... Soooo I will also pick up the medium/pot, to see how heavy it is.. too heavy, good on feeding..light feeling needs water. Happy Growing!
Hey dude - seedlings look good! Watering frequency is a tricky question but the general rule of thumb is to water your medium through with about 10% runoff out the bottom. That said, cannabis generally prefers “cycles” of dry and wet soil. Let the medium dictate how much you water them. If after a few days (prob. 5-6 at this stage) the soil is dry up to the first knuckle of your finger - it’s provably time to water. If it still feels moist, let em dry out more. This will vary by strain and growing conditions but it’s a pretty good rule of thumb. Hope it helps and good luck!!!:+1::facepunch:
