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:
Hi @JReady! If you're not using foliar sprays, you can water every 2-3 days, but you'll need to judge by yourself, looking at the plant's leaves and the soil's dryness. Your soil need to be on a wet/dry cycle, however each phase should be pretty quick, you don't want a too dry medium neither than a wet medium for too long. That's why it's important to water with maximum 20% of your container's size. And if you want the roots to spread, you better water on the outside-border of the container, not in the middle. Hope this helps, keep us up-to-date and happy growing! :facepunch:
@Stick, thanks for that info im a newbie and are making mistakes left and right. But my girls are still growing. I will take your advice and any other advice from a pro. :peace_symbol:️

I water every third day and spray them down every other day with RO water and liquid see weed

Hi you should water when soil is dry and about every 5 days :+1:
This strain may have come from us but its one of Bomb Seeds strains.
@Seedsman, thanks for clearing that up for me. I got some Mama Mia from you also. I'll be showing next . :peace_symbol:️
Good luck with the grow ;)
