Benzelsanswered grow question 3 years ago Per day? Never water each day unless your in a tiny pot and in a media mix- something heavy with coco. I see your in week one, I also have a seedling in week 1, Its currently in a 55mm jiffy pellet and im giving it maybe 15 mls of water a day just to keep the pellet damp. Its outside in 30-50% humidity atm and its around 30C here each day too. Once its in soil outside, I will water it every 3 -5 days for the first two weeks, And not much water each time either... After that its every 5-7 days and its gets a bit more water than when it was every 3-5 days. Cannabis plant roots need more oxygen than most people realize and if you water that often, you wont be letting air in as the media will be saturated with water.
But the biggest issue u face if you water too often is root rot, water every day if the soil isnt dry enough to need it and you WILL eventually get root rot outdoors. The other thing thats vital in veg is you NEED to be a bit mean to them when they are big enough to take it, thats about week 4 or so. Thats when you start watering a bit less often or a smaller amount than normal now and again and make the plants roots hunt out water and grow bigger, bigger roots = bigger plant= bigger buds. If u water all the time why would the plant waste energy growing bigger roots?? it wont. It doesnt need to, cause your bottle feeding the baby instead of being mean. Good parents make bad growers normally until they learn this..lols. And if the plant has small roots going into flower u get smaller buds and plant gets stressed easily.
So cant say how much to use and how often, the weather changes so your watering has to adapt too. When the plants need it, thats when you water when they are around 4 week old, When they look thirsty and the soil looks dry. Outdoors i get sunburnt just watching my plants grow each day and not doing anything to them, if you watch them enough you will learn what they look like when they have just been watered, when they are still happy from last watering, when they look thirsty and when they really REALLY need a drink. Its all stuf fu learn with time and by watching the plant. But if you need a rough rule of thumb, less water more often when smaller, more water less often as they get bigger. In veg its vital at least a few times you let them wilt a lil bit from lack of water, just a slight wilt ok, very very minor, and then give them a bigger than average soaking. But later on in the veg cycle too, not too soon.
