Questions about field capcity, starting out "dry", etc.
    #26828857 - 07/17/20 12:13 PM (3 years, 6 months ago)

Hello All,

It seems field capacity is a little more subjective than i previously thought. Some say only a few droplets with a hard squeeze, some say a lot of droplets to almost a stream. Is there an actual measurement that we can reference using a soil/sub hygrometer? We are experimenting with prepping on the drier side. Maybe 2-3 droplets per squeeze. Anyone else prepping drier?

Many Thanks!

IMO the "a few drops" measure is a safe rule of thumb for really new people. It definitely works, but more moisture than that is ideal IME. It's just hard to explain with words what the actual perfect field capacity is.

A few drops is safe and works, but a little more is better, but a bit more than that is too much.

I like to have it just on the border between drops and a stream, if that makes sense.

For shoeboxes, many get great results, and less side pins, by prepping on the dry side initially, then giving a heavy mist right after spawning.

The reason why you don't see any measurements to reference is because coir can vary quite a bit in absorbance, even within the same brand. Moisture level is one of the things in this hobby that requires experience and trial and error until you, personally, have a feel for it.

Like the person above said, field capacity is really an odd concept to accurately express through text so most descriptions give a broad method to start from. After that, you'll start altering the moisture of your sub based off your environment and fruiting method.

I personally make mine like this. Light squeeze: a few drops. Hard squeeze: a stream. That has been the most effective measure for me. I think eatyualive has a nice little video in one of their coir writeups.

I shoot for a small trickle that lasts a fraction of a second and ends in a few drops when palm full is squeezed med-hard.

Aim on the dry side when starting out is good advice for sure. Better be a little dry than a little wet

Thanks guys. I have done enough sub to know what most people refer to as field capacity, but i certainly appreciate the videos etc..

Recently we are trying slightly drier, about 2-3 drops with a hard squeeze and then a quick 5 sec spray before sealing up for 5-7 days. Will this be enough moisture to spawn to bulk? They have only just been started.

Clearly we are trying to eliminate over moisture than can lead to contams. The coir/verm is prepared about 2-3 days in advance using only bucket tek that is modified for large capacity with open air spawn to bulk . I am still slightly concerned about potential contams with the bucket tek method however and have also moved to a closed room.

My shoeboxes are on the drier side this time and I don’t like it. Like dude said above, aim for in between a couple drops and a small stream.

Got it :smile: i will see how these drier ones turn out. I have also done a few with a final misting right before sealing up for about 5-7 days.

The main difference I’ve seen is when it’s drier it’ll need to be hydrated after the first flush, otherwise it’ll be fine as is for two flushes.

I'll keep close watch on the drier ones and report the details.

Too subjective. How many psi can you squeeze? What might be a hard squeeze for you might be someone else's medium.
Do something, document, improve.

I agree the subjectivity bothers me a little (i am OCD lol). Isnt there a hygrometer reading we can reference?

The bucket tek method is completely sufficient for pasteurizing without contams.

I personally just use hot water from the bathtub into a tote to make my subs now and even that is sufficient. The contams you're experiencing aren't from your moisture content. They are from your spawn and until you correct that you will continue to see contamination no matter how dry you make it. I tried this when I first started.

Edit: as for your question, yes it will be sufficient but your flushes will suffer unless you bottom water a good bit which can lead to bacterial issues in already contaminated material
