Which is the Best Way of Watering Marijuana Planted in Soil?
Obviously, one of the first questions which occurs to first-timers in cannabis cultivation is about watering their marijuana plants. On one hand, it’s known that marijuana demands a considerable amount of water, on the other hand, these weed plants don’t have high tolerance to overwatering, so you need to balance this out. Here are some practical tips on how to develop a proper watering schedule. And keep out from underwatering or overwatering your marijuana plants.
Watering Schedule for Marijuana Plants
Marijuana is such a plant which doesn’t stand constant baths, so wait until the soil dries up till the next watering. Here are some rules to follow, while calculating the demanded amount of water for each separate marijuana plant: use as much water as 1/4 (quarter) of pot’s volume in which your plant resides.
As a rule, I water my marijuana plants slowly and steadily all over the surface of the soil to make sure that all of it gets an equal amount of moisture.
Lazy Watering technique for Marijuana
Another useful idea is to put pot plates underneath the pots and pour water into them. It will be absorbed later within a day and will provide equal moisture for the soil, both at the top and at the bottom of the pot. Make sure you use substrate of equal density all the way through the pot and don’t forget about a proper drainage like some perlite, coco coir, or clay pebbles.
After watering the plants, you may notice that the planting containers are rather heavy at the moment and you will probably find it difficult to move them. Another nice way to understand the need of watering is to weigh pots every day, not even necessarily with some equipment as your hands are enough. Compare the weight of dry soil and the weight of pot with watered one. When they have equal weight, it is the right time to water your marijuana plants. As water is heavier than substrate it will take a little bit of practice to understand the proper time for irrigation, depending on the weight of a pot.
This approach appears to be rather efficient and comfortable for cultivating cannabis or any type of plants in the pots. In case of using this approach, you will probably come off with a schedule of watering like every 3 to 6 days. But don’t forget that external factors like level of humidity, size of a pot and amount of sunlight can influence your watering schedule a lot.
PH Levels Friendly to Marijuana
Demanded acidity of soil and water is ~6.0 – 7.0 pH. PH level of water changes pH levels of soil considerably. PH level of soil can be found on any soil package. As a rule it is ~5.0 – 7.5 pH.
Naturally, marijuana plants prefer to grow in a soil which is slightly acidic. The finest pH level for the root zone is about 6.0 to 7.0, but make sure that the majority of time is spent in the conditions with pH in the frame of 6.2-6.9.
In case of growing marijuana in soil, you are considerably less likely to face any pH problems, mostly, if you decided to use some professionally mixed soils that fertilize marijuana plants all their life, without any necessity to input any other liquid nutrients.
There’s an opinion that the soil performs a role of a barrier, hence it assists to slow down the fluctuation of pH values on the contrary to hydro systems where any changes in the level of pH influence the plant considerably quicker. Making soil a better choice for minor errors in growing process.
Usage of pH Test Strips
pH test strips are available in all big stores, pharmacies, or specialized shops. Their price is about 3-15 USD.
If a shop assistant doesn’t have a clue what you are asking for, here’s a tip: pH testers are sometimes also called litmus papers and usually look like yellow papers shaped like a tape or white plastic strips. They are used in the following way – you put them into the water to measure the pH level. Pay attention to the fact that the paper version of this tester is much more cost-effective.
Way of Testing pH
Here’s when you will finally have a possibility to use the knowledge of the chemistry class practically. The litmus paper changes color when being put into different environments like an ordinary water, a soapy water, or into a lemon juice. Did that? Congrats, you are capable of measuring pH level of liquids.
OK, remember your science lesson at school and follow these instructions:
The best way to adjust pH level of water is to buy a “pH Up” or “pH Down” kit, wide range of which is available both online and offline.
