How much run-off?

[cuy103]

Just an information question.

I didn't notice this until I did my watering today.

I was trying to get a good sample of run off to test for the ph of the soil.
As I was gathering the run off I noticed how much "ran" off.

I am growing in 1 gallon pots with FFOC. I gave them 1 gallon of water each and I got 1/2 gallon of run off!

What's your experience?

are you watering that much to get water to test or do you always water that much? it seems excessive.

i was flushing

how much do you water them normally? you gotta figure a gal pot holds 1gal o f water, so a loose airy mix+roots can only be so dense in comparison to water. so if it is half as dense as water(so .5g/cm3) 1gal would only occupie half a gallon of actual space and so .5gal would fill the pot.

Here's a sticky that has LOTS of info on watering, runoff and how to arrive at the proper amount of watering for your plants:

Good Luck!

A good rule of thumb is to water 20% the volume of your container to begin with. After that, you will kind of feel it out for yourself. As in: 5 gallon container--water with one gallon.

Aren't 1 gallon pots sorta small?

Thanks everyone.

But I was just asking as an information question.

I know exactly how much to water my plants and how much they need. They are on a specific feeding schedule. I give them plenty of water and plenty of oxygen during the dry cycle.

Like you said PencilHead, I give them around 20% of their container size and it works fine. Yeah, one gallon pots are relatively small but I have a small space.

Thanks Lotek. That makes sense to me. Maybe that's why I had so much run off.

I was just wondering what everyone else experience was with run off, that's all...

You say JUMP and we say HOW HIGH?

Okay...

So I watered tonight and here's my runoff amounts. I have two 10 gallon pots with two plants per pot. I've been alternating feedings with water and I'm on the first day of week 6 of flowering. I've had to water every 3-4 days early in this grow and now it's every 2-3 days depending on soil conditions and listening to the girls when they tell me it's time. Tonight I gave my girls a s-l-o-w watering, about 1/2 gallon each and then I'd let it soak in and come back 10 minutes later and add another 1/2 gallon. I repeated this process until I noticed some runoff and then I stopped. I ended up giving them about 2.5 gallons each. I got a little more than a quart of runoff from one pot and a little less than a quart off of the 2nd one which is about what I usually get I guess. My nute ph was 6.3 going in and the runoff was 6.1 coming out... It has been coming back 6.5 til now and I think it was a bit lower because I gave the girls a soil drench of a product I found online called TerraVive on the last watering. It's humic acid based soil conditioner with soil beneficial bacteria added. My ph probe still reads 6.5 so I think it's all good... the girls are in the home stretch!

Any-hooo... that's the skinny...

Peace!
