The Official Hempy Bucket Thread

[G.O. Joe]

I am looking for something to run hydro drain to waste

You might like rockwool cubes. Sounds off topic but a big cube or a 4" cube on top of a 6" cube is really just a hempy bucket without the bucket.

I did perlite "hempy buckets" before it was so named (1986), perlite/vermiculite, promix, soil - and will never do those again because rockwool cubes define no muss no fuss.

Really Jo, where is the internal Rez is it's the same ?

I didn't name it the hempy bucket others did at Cannabis world around 2000 when I first posted about it and I came up with this around 83 and no one including the Guy I got my nutrients and medium from as there was no hydro stores back then who was in businesses since 1969 had also not heard of it or did he feel it would work.

This is why I don't waste my time in these threads any more, its mostly full of negative people like you Jo who really has nothing positive to add.

At the bottom of the cube.

The only negativity here is coming from you! Nothing positive to add? Well, in this post maybe.

And this is why I don't post any more!

There is no internal Rez in Rock Wool Jo move on.

I grew up in a family business that involved growing hydroponic cut flowers in rockwool slabs in the late 70s, early 80s. The slabs were wrapped in plastic. To drain you cut a slit in the bag about half an inch from the bottom, so they in fact had a reservoir. You'd cut squares on top and the rockwool cubes used to sit on top allowing the roots down into the slab. Hope I've explained it ok.

Hempy buckets are a great idea but the concept isn't new in the world of hydroponics.

So how does Rock Wool the medium have an internal reservoir Chi ?

The rockwool slabs are completely enclosed in plastic. A slit is cut about half inch from the bottom for drainage, meaning under that cut is a permanent reservoir. They are watered via spagetti tube through the top, but always retain a reservoir of solution in the bottom. It's hard to picture but if you look up "grodan rockwool slabs" you should get the idea. Plants were started as cutting in rockwool cubes. You then cut holes in the top of the rockwool slabs and the cubes just sat on top and rooted into the slab.

I might add I learned everything about hydroponics from my dad, an ag scientist with over 40 years experience with hydroponics. He actually referred to it as a reservoir, and it reduced the risk of things drying out if there was some disaster like a pump failure.

The person that was heavily involved in hydroponics in Australia from 1969 and Growers from all over the world back in the late 90s did not believe it would work, So how was this concept main stream Chi ?

I was the guy that freely shared this concept of growing I fine-tuned over some years, and most said it would cause root rot.

I know how Rock Wool comes in Chi and most set it up to drain to waste, but you know that, right ?

So when it's run for flood and drain or drain to waste, how does ROCK WOOL THE MEDIUM have a built-in reservoir ?

It doesn't have a built-in reservoir, does it Chi.

This medium does not have a built-in reservoir.

If RW with the Plant is allowed to sit in water or water rich nutrients, the roots will rot.

I've explained it twice. The reservoir is in the rockwool SLAB, not the cube. The roots don't rot because they are watered between 3 and 6 times a day and the reservoir is constantly renewed with fresh nutrients.

Grodan Wrapped Slabs

Grodan horticultural grade rockwool consists of a mat of long, fine fibres, spun from molten natural rock. It is inorganic and inert.

Don't be an arsehole with "smart enough" comment. I am not trying to argue, just contributing to the topic. I worked in commercial hydroponics for 20 years, my dad 40. I know exactly what I'm talking about.

You should take your own advice, Chi.

Move on.

Can you just quit the bickering and insults?

doesn't really seem like it.

 

[Rocket Soul]

Looking for info and stumble into this. No thx, ill look for it elsewhere.

The rockwool explanation was easy to understand once explained with a cut. Not sure why anything would anger someone like that. Happy keyboardwarring guys

Do you know who Joseph Romer is, Chi ?

He had the first hydroponics company in Australia, it was started in 1969 he has published 9 or more books, on hydroponics he supplied both farmers and hobbyists.

I found him in 1983 where I bought my first nutrients and medium and lights from him.

A few years later, I told him about my concept, he also did not think it would work, but he was intrigued by it. So I know this concept did not exist from people that would have known.

I take great offence by people like you that just dismiss my contribution and act like it was out there before I shared it.

Sounds like you were running a flood to drain to me, Chi.

The hempy bucket only needs watering once the medium and rez is dry, and depending on the size of the plant and temperatures that could be from daily with 7 ft plants in summer to many days between watering/feeding with smaller plants.

I can't recall any authors names from that time but I looked him up and some of the covers look familiar. Maybe my dad had some of his books? I will ask him.

It was flood and drain, but with a reservoir. The rockwool slabs always had a half inch of reservoir due to the fact that the drain slit was half an inch from the bottom. I'm not saying what we were doing was like hempy buckets; it was not, but the concept of having a reservoir is not new.

I was not dismissing your contribution at all. You are taking it the wrong way (as usual).

 

[LostTribe]

For crying out loud you guys, leave Hempy alone. The thread is about Hempy Buckets stick to the script. If you arent running these buckets keep your comments to yourselves, I'm not interested in growing little piss ant micro plants in some tiny ass cubes and already have buckets with proper holes from my hydroton recir system which I am repurposing as hempy buckets.

I have my seedlings in pure perlite. Mini hempy's just solo cups with one hole each about half inch up from the bottoms. They are all looking nice 2w in.

I am feeding GH salt based nutes(maxibloom) at 1.2ec ph 5.7 every day or two depending on how heavy the cups feel.

Should these be flushed with ph'd RO every 2 weeks like I do in recirculating hydro? Thank you all and peace be unto all.

Hempy just PM me if you wish to respond. I am sure I will find the info when I get time to look further thru the thread assuming off topic comments arent spamming the entire thread.

 

[@hempy]

I wouldn't flush with water unless I am about to harvest, if it concerns you, sure check the run but all I do is make sure my nutrients are at the EC and PH before feed them, that's it.

I like Coco core these days with perlite in the Rez to allow the coco to drain correctly, I have posted that up in the coco section I have used this now for many years.

This method is as simple as it gets, but it produces the best results I have found.

 

[G.O. Joe]

If you were really smart, you would have figured out the concept behind the hempy bucket.

It happens to be the exact concept I was referring to with the RW cubes.

This can be easily quantified. so a little experiment was done. But, I don't have any perlite to compare the results with.

2 standard grodan 4" cubes were weighed dry, saturated with water, then 1 was placed on top of the other - the equivalent of a 2 liter container. This was drained on top of a screen for 15 minutes, at which point water had long stopped dripping off. The cubes were weighed separately. The top cube went from 72.8 to 353.7 g - a water content of 280.9 g/L. The bottom cube went from 70.8 to 865.3 g - 794.5 mL/L water. Tell me again how this is not comparable.

I actually do have all my cubes standing in buckets, but this is to catch runoff, because bad pH things happen to me in flower without runoff.
