Watering my plants

[GRAPEapeGorilla]

I keep hearing about you want 20% runoff how is this determined or measured? A lot confused

"Every time you water your plants, make sure that you provide enough water to get about 10-20% extra run-off out the bottom of the container, especially if you're feeding additional nutrients in the water.

The reason for this is that sometimes soil and soilless growing mediums like coco coir start to form natural salts if it the fertilizers just sit in there and never get washed out.

These built-up salts can eventually cause nutrient problems, pH problems, and nutrient lock-out if they're not rinsed out.

Making sure you keep adding water until you get run-off is also a great way to make sure that your plants are draining properly.

Plus, this practice will immediately alert you to any drainage problems, (as mentioned earlier, cannabis likes well-draining soil) because you'll be able to notice if the water takes a long time to come out the bottom, or doesn't come out at all."

Basically, you want to over water the pots they are in based on the volume of the water going into your plant container. Let's say you use a 5 gallon container to water your plants. The runoff at 20% would be 1 gallon so you would want to water your plant with 6 gallons instead of 5. Likewise, 10% runoff would be .5 gallon so you would use 5.5 gallons instead of just 5. If you water your plants with only 1 gallon, 20% more would be .2 gallons (or an extra ~25oz) and 10% would be .1 gallon (or an extra ~13oz).

If you are growing in organic soil, or a peat bases medium, then no. In soil you would wash out the nutrients, and in peat based you will have so much water in the pot it can drowned the roots.

In coco, you can water until you start to get runoff. Once runoff starts, you can assume that everything you put in after that will be adding to the amount of runoff.

The purpose of runoff is to wash out salts. If you use chemical nutrients you will get salt buildup and it will start to lower your PH. If not 'flushed' out the PH will get so low that the plant can not take up nutrients properly. The use of a 'flushing agent' compatible with your nutrient line improves the effectiveness of the flush.

You should get back 1/5 of the water you put in if you are tryi g for 20% runoff. I just water until my plant flows water then drain, completley.

I water daily feed every other day just enough to wear it trickles out the bottom a little bit my two cents overpaid at that good luck. You're going to want to learn to check the pH before it goes in and after it comes out that'll tell you lots and lots of what you need to know.

Failed to mention I'm in Coco not dirt, dirt really depends on humidity temperature size of the plant size of the container. I do have a couple in dirt generally just pick him up when they're light I water them when they're heavy I leave them alone.

We could quible about the details but you ans I are really on the same page; is it light? Water it.
