Watering

Waynski
Waynskistarted grow question 3 years ago
How much water should be added to a plant at each stage per day? Is it better to skip a day? Was thinking of doing a flood once a day but not really sure about exact values of water. Outdoor plants in full sun and south facing in northern hemisphere

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.

Deep watering every few days is much better than frequent watering. Wait until the top 1cm has dried out before watering again for seedlings. With established plants, wait until the top 2-4cm have dried out before watering again. A small plant/seedling might need only between 100ml and 1000ml and a large mature plant in hot weather might need between 10 litres and 50 litres at each watering. It all depends on temps, plant requirements, the wind and the water holding capacity of the soil, so it is impossible to say give x litres every x days. However, never water every day "just because", you want your plants to send its roots deep and frequent watering will keep the roots shallow, which can lead to plants falling over in high winds or when heavy with buds. Just make sure to give a good amount to penetrate deep down in the soil and then not to water until things dry out again. You will soon get the hang of it and will eventually "just know" when to water and how much to give each plant. Hope this helps, Organoman.

Hey Growmie, When they’re seedlings, you’ll need to water them frequently to ensure that the soil is always moist. But you’ll need to cut back after a month or two. Once they’re mature, you can water them once a week. However, you’ll need to do it more frequently if your environment has porous soil or you live in a dry and sunny area. Now the amount of water they need will depend on various factors such as the strain of the plant, the weather, soil, and intensity of the sun, among other things. Feel free to shoot me a holler if you ever need any help, I'd be honored to assist you. Hopefully, this was helpful, and remember ... "Happy Growing" and "Free your mind one puff at a time".
