Earthworm castings

[ThaiDye]

I've Been collecting the ingredients for Super Soil and was wondering if anybody had info on how much 15 gallons of earthworm casting in weight or 30lbs in gallons or cu.ft. Looking at one 30lbs bag seem only like 5 gallons or so. Any help would be nice as I'm mixing sunday and don't want to do part ratios because I come up short and my local shop is closed.

lol i miss president bush he was quality.

i think 15 gallons is 3 cu ft, if thats what your asking

 

[kushking42]

a cubic foot is about 30# and fills a five gallon bucket

 

[SpicySativa]

1 cubic ft is about 7.5 gal.

 

[kushking42]

1 cubic ft is about 7.5 gal.

whoops ya your right. its 7.5 which is definitely more than a 5 gal water bucket.

you really cant do too much EWC. that is the life blood in soil...the more the merrier in my opinion. in sub recipe i always use the high end number for EWC.

ya ur right. i go with 20 percent of my total mix. drainage is only thing limiting more

i found the cut off to be 20% also.....and i will use the whole 20 fucking %.......imho, the most important soil ingredient for a successful grow.

5.4 cubic feet per yard

Wow a lot was lost in translation I guess. What I meant was I have a 30lbs bag of earth worm castings. Sir Sticky's recipe calls for 15 gallons of earthworm castings. Has anybody actually measured a volume amount to find actual weight. 1 gallon = 7.48 cu.ft. is a simple conversion but I need to know how much in weight, how much I will need since that is how it's sold. Looking at the bag, I'd say 5 Gallons seems correct. Like saying 1 gallon of water weights 8.35lbs. (X) gallons = 30lbs. of earthworm castings, find X.

 

[kushking42]

weight will vary due to moisture content. but a cubic foot of castings is about 30#'s. 1 cubic foot: 7.5 gal. both were already stated earlier

Alright, I went and did some science stuff and found 1/2 cup is 68 grams. Through basic conversion formula, I came up with roughly 6.25 gallons per 30lbs of earthworm castings. Sorry to waste everyone's time.

It's not always going to be 1/2 cup is 68 grams, it's all going to depend on the moisture content in the castings. I bought a 15lb bag the other day and I'm pretty sure there was about 3.5 gallons in it. I measured out 3 gallons to use and there was about 1/2 gallon left in the bag.


Gallons to cubic feet or the other way around are f'n confusing.
1 cubic foot is about 7.5 liquid gallons
1 cubic foot is about 6.5 dry gallons
The horticulture industry and their pots are usually measured by trade gallons which are even smaller than a dry gallon. 1 cubic foot is about 5.3 trade gallons.
edit - I think I did the math wrong and 1 cubic foot might be about 10.5 trade gallons. This shit is too confusing.

I used Liquid considering everything I can use to measure is in that standard. Went back to the store and got 60lbs more. All 4 bags I have came up to 67.8, 67.7, 68.2 and 68.4, So I just used 68 to 1/2 cup as a base. Also Considering that some of it was clumped together adding extra weight to the volume, but I got what I needed to know. Still not enough for both base and super soil.

Oh my god, I had to register for an account just reply to this. I almost died laughing at this follow up comment to all of the above responses. I am an agronomist and do these types of calcs and conversions for a living. Good job on doing your science stuff! and now I get to use this helpful info in my calculation so I don't have to go out and measure it myself. They should really put a wt/v ratio on the bags. Thanks for the help as well as the entertainment.
