Fireknot farm 2016

Basically I've just shot for 10% soil volume this entire time. The frequency was determined by how they looked. Ive never let them droop super bad but if a few do a little bit I know they're good. This past week they just started disliking every 3. There is more wind and theyre bigger it makes sense. Tomorrow I expect to see a good response from 33 gallons with the sea blast and compost tea extract. I need to go buy six bags of ice right now to wash this trim with.

I'm not sure if my plants are as big as yours but if I don't water them at least 20 gallons a day they get real droopy. On hot days I'll give them at least 40 gallons a day. That's way up here in the north too. You ever think about watering every day?

Dank,

That is a lot of water.

Many folk over water and at the same time the plants don't get enough water.

That means that the water is put on too fast, runs through and then out and then the plants get too dried out and need water.

Is it possible to have a meaningful discussion about watering amounts without talking about soil volume and plant size and weather?

Obviously a plant in one yard is going to have different water requirements then a plant in a 5 yard mound right next to it, assuming the plant is using all of the available soil space.

Planting,

I enjoy your obvious comments. Unfortunately, the same plant at the same size in your neighbors yard, needs the same amount of water. Evaporation is evaporation is evaporation.

What will be different in your neighbors yard, on his or her plant, will be water retention in the soil or medium. That is a different animal.

And the factors that are involved are the volume of the soil if in a closed container, size of the plant, wind and relative humidity.

Slownickel, i didn't mean neighbors yard, I meant one yd of soil vs five yds of soil, right next to each other. Just takes more to wet. So if 50 gal every three days is good for Tess in one yd or whatever he has, I don't know how it scales up for five yards but you're getting closer to 100 gal a day. What am I missing?
 
Each site is ~500 gallons of soil. If I had twice that I would do 10% or 100 gallons and wait to see until they needed more via their behavior. Mulch makes water retention easier btw.

Looks like I'll finish around 3 today instead of 7.

Personally I notice zero indication from the plants they need or want water every day at this point. That may change but the weathers cooling down. So far so good...will be watching them closely like I always do.

Dank,

That means that the water is put on too fast, runs through and then out and then the plants get too dried out and need water.

That is why I set my irrigation to come on 3x per day at light-ish to medium saturation over one heavy.
 
As 1 barrel fills I empty the other one on two plants. So they get watered in intervals. I've effectively eliminated any runoff by doing this and with my top watering pattern. I could see how that may be useful for drip though if you didn't dig trenches around the center.

Nice to get off work early but I know it isn't going to last. One of the plants was starting to twist away already. I'll see how they look tomorrow and give them a bit if I need to but I bet I'll have to bump it up to 50 every other day.

Cannacoco oil yam brownies...Mr. Robot...maybe some sunset pics later now that they're bulking up and look awesome as silhouettes. Gotta throw this bubble in the freezer now too.

Thanks DAT...and thanks to everyones help along the way. Still tons of room for improvement too!

Yes, I agree. There is a difference.

My 100 gallon pot dries out daily, with a fairly large plant.

My 1000 gallon plant goes 3 days with the same gallon of water per gallon of soil ratio, with a much larger plant.

There is a difference for sure, how to calculate I don't know. However what slownickel refers to in the geographical maps showing evaporation rates is for native soil, with acres and acres around it, with only the top surface area exposed to air. My smart post are the opposite, and only the surface area of the bottom is touching other soil.

Trippin on this the other day/week. Please correct me if wrong SlowNickel or anybody. :tiphat:

Evaporation from the surface of the soil, believe it or not, is a minimal loss of water.

When I speak of evaporation, we are talking about what is evaporated from the plant. The more plant the more evaporation.

If you wet an area that has no roots, that water doesn't count either. And if you have a huge plant in a small container, it needs the same amount of water as if it were in a big pot.

Wetting all the medium is water that can be used if there are roots there only.
