Tips on How to Water your Marijuana Plants
Tips on how to water your Marijuana Plants: lots of growers have some serious queries about what watering your plants actually meamns. These issues have becom commonplace thanks to the myth that if the first cm of soil is dry you need to water your plant. This is not true, because if your plant isn’t even 10cm tall, and it’s in a 7L pot, it’s extremely likely that the top layer of soil will dry out before the plant can suck up all of the water in the pot. This means that if you water it again just based on the top layer being dry, you’ll end up soaking the bottom layer of the pot, meaning that the little hairs that absorb water through the roots will burn out and won’t be able to absorb any more water.
You need to water your marijuana plants with moderation, always adapting to the size of the plant. Obviously, a small, brand new plant isn’t going to need as much water as a plant that’s been alive for a month. The bigger the plant, the more water it needs, and vice versa. The best method to check how much water you need is to check the weight of your plant before and after watering it.
The first thing you should do before watering your plant is to check if it has absorbed all of the water from the previous watering. If the soil is still humid, there’s no need to give it any more water. If you have a lot of plants, this can be hard work, but if you neglect to do it you’ll be complaining about having small plants, plants that aren’t growing, yellowish leaves etc.
Steps you should follow:
- Germinate your seeds with the Tupperware system that we’ve explained in a different article.
- Once the root is showing, stick it in a 7×7 pot, already watered, at about half a centimeter to a centimeter from the top. There’s no need to water again until the sapling has begun to surface, and only when the pot is no longer weighed down by the water inside.
- Once the plant has started to stretch upwards, you should move it to a 3L flower pot. Once transplanted, you should water it with about a half liter of water more or less, depending on the soil. You need to lift up the pot every day until you notice that it’s not heavy at all. That’s when you should begin testing the water levels.
- Start with one glass of water a day per pot. If after three days the water has built up, you should stop watering it until it’s light again. Then, continue giving it one glass of water a day.
- When one glass a day isn’t enough, you can amp it up to two glasses a day. Once again, if the water starts accumulating, let the plant drink it all down. Never assume that all of your plants absorb water at the same rate; you have to check them all, every time. Once you notice your plants stop growing, they need to be transplanted. Right about now, your plant should have a decent root system going on, making them eligible for a ground transplant or a 7L flower pot.
- When transplanting to a 7L pot, I tend to use about a liter of water, because when your plant is this big, in a pot this size, it’s easier for it to dry up. This means that you should increase the quantity of water every day, all the while checking the weight of the pot to make sure it actually needs water. Do not water your plant based purely on the top layer of soil because most of the roots are concentrated from the middle downwards. Right about this stage is when you should begin flowering indoor plants. After about a week or 10 days training your plants to absorb water it’ll be very difficult for you to damage the roots because the training will have made them stronger and able to drink a lot more water.
- For outdoor growing, you’ll notice that the soil isn’t drying, and if you keep watering it when it’s still humid the plants will start shedding their leaves as if they need water. This is because if you soak your plants, you damage the little hairs that absorb water, so the plant can’t actually drink, and it will eventually die if you don’t do something to save it. To save your plant, you need to let the soil dry completely, and then start watering it again with a small amount of water, and product that will help heal the roots, like Hesi’s Root Complex, if you don’t mind using chemicals, or Bio-Rhizotonic if you use organic compost.
- The times you’ll most want to avoid soaking your plant are at the beginning and end of its life. If you soak it too early, you can end up killing the plant right away. If you soak it towards the end, near the harvest, you’ll end up with soil that won’t dry and you won’t be able to harvest it because the end product might end up moldy, and if you leave it there, it might get moldy from the wet ground anyway. Your best bet is to be extremely careful when watering your plants at the start and towards the end. Your plant will tell you when it needs to be cut, because every day it’ll absorb a certain amount of water. Once it suddenly stops drinking, you have your warning. If it stops drinking and you continue to water it, I’m afraid you’ll be in deep waters with the end result.
- Always water your plants slowly, check the Ph levels of the water and your plants will be healthy and strong.
These are all the tips that we have, but if we think of any more we’ll add them on. If you take this information on board when watering your plants, you’ll definitely make a lot less mistakes.
