The Official Hempy Bucket Thread

[dubwise]

@dans-in regard to watering schedule....for me with the 70-perlite/30-vermiculite mix, newly rooted clones, seedlings and plants in flower get fed every day (albeit different quantity) and the girls in veg get fed every other day. It varies a bit during the heat of the summer, our veg room tends to get warmer in the summer and the plants will require more frequent feeding then.

Just thought I would share this with everybody

I mentioned earlier in the thread that they actually sell pre-made "hempy buckets" here.
tear drop shaped hole is the drain and the one below is a plug if you need to drain more.

 

[real ting]

Anyone run their hempy buckets with a drip system for feeding?

What you are describing is called a bato bucket or dutch pots.

NICE! Like the holes for stakes around the rim too. Very nice features. How much do they cost?

Also what size are they?

 

[Japanfreakier]

They were like 5 bucks and 15 liters I think. They have those air-slits above the drain point as well, not sure what effect that would have but I just wanted to show that this idea has been around a while and used all over the world.

Nice size & decent price.

Very true that similar setups have been around for awhile. I remember as a child my Thai grandmother using coconut hulls as pots, filled with chopped up coconut husks (early version of coco coir maybe?) for her orchids.

Hempy brought this style to the MJ masses and maybe he had never seen similiar setups before but in reality it's not a totally new concept.

Anyway wonder if those pots will ever make their way to the US. Wouldn't mind having some of those.

Mary Janes Garden brought them to the MJ masses...decades ago.

 

[Japanfreakier]

lol, I think you mean Emily's garden?

 

[Bonavendura]

I like those air-slits above the drain point i will make them to my new Hempy's .
I dont think that they can cause something bad (maybe quicker dry out ?)

Hey pls give me some help in my sig's growroom setup/sketch up

You'd be wrong again, Jr.

 

[Japanfreakier]

lol, Jr is it now? Anything you say gramps.

Perlite is not going to help in increasing oxygen levels. It can only have as much oxygen in it as the water holds. Oxygen bubbles will seek high ground, and won't stay in the perlite similar to an oxygen reservoir, which seems to be what you would be thinking.
Trapped air bubbles does not dissolved oxygen make.

These types of buckets are basically a hydro system, and DO is very important in a hydro system. Some hydro systems recirculate the water, nutes, and oxygen. So, I have a hard time buying that one can water too often using this style of bucket grow.
One can surely not water often enough to keep plenty of DO in and anaerobic bacteria out.
You can take the guesswork out of the oxygen equation by adding 30ml/gal of H202 at each feed. Some left over? Foliar spray it. Plants absolutely love the stuff and will show it.Perlite is not going to help in increasing oxygen levels. It can only have as much oxygen in it as the water holds.

Your understanding of active vs passive hydro is erroneous. you dont need to actively add DO in Passive hydro, as roots arent saturated in water.
DO via breaking the surface tension via water pump or DO via air stones and air pumps are only utilised when roots are stting totally in solution. (DWC)
With Hempy buckets the roots are in an aerated medium (perlite) and dont need to have DO in the nute solution because lo and behold all the air is trapped in the perlite, Nute solution is 2 inches (including perlite and roots) the rest perlite containing air.
Whether you like it or not perlite traps air and whether you like it or not this air will e provide oxygen to the rootzone.
I would suggest studying up the actual dictionary definition of hydroponics as well as the greek origin to gain a full understanding.
A horticultural course would iron out all the flaws in your logic too. Perhaps look up dictionary meaning of Osmosis and Diffusion. Throw in Turgidity and the Transpiration Stream, and how this relates to intake of nutrient in a linear and constant manner and how DO in a nute solution is rendundant when applied to a Hempy bucket.

 

[Baba Ku]

Aren't the roots saturated in solution below the seep?
And how do we suppose we are adding oxygen to that solution once the initial charge has been depleted? Don't we add oxygen by simply feeding solution, and the DO that is created at that time is what the solution gets? Are we to assume that the addition of perlite in that wet zone give us an advantage? I mean, there is only the oxygen presented to the solution at the time of feed available and if there is, or is not, any perlite in that zone it does not increase the level of DO.

Is there benefit from the perlite in that zone once the oxygen has been depleted? Let's assume two buckets, one filled with perlite, and the other from the top down to the seep with perlite, but further down just solution. Will one bucket hold more DO in the "wet" zone below the seep than the other?

 

[Two-Dogs]

Like I said , do some study, go back, re- read my post, pick out keywords that I mentioned, google them.
All the answers to resolving your rudimentary comprehension of Hydroponics is contained within those words.

 

[Baba Ku]

Surely one so astute in the art of hydroponics and horticulture could provide a simple explanation that was easy for the layman to understand?
Or are you here to nip pick and critique, and sod helping anyone?
Anyone can point to a book...with an air of understanding. Perhaps the true test of their understanding would be if they could convey it to others?

 

[Two-Dogs]

Lol Talk about biting the hand that feeds you. I just provided you with so much keystone info and you still refuse to learn. Im not going to take an hour to type out what will take the average bear two minutes to comprehend when you can just google it.
To explain anything properly to you I have to know you understand these concepts so we are on a level playing field, however I suspect when you google them ur bad self you might just understand these concepts and all your questions will be answered making my explanation redundant.

This is all high school biology stuff, and can be found in jnr high school biology text books. foundations are always handy to have, as Nicollo Machiavelli says "He who has not first laid his foundations may be able with great ability to lay them afterwards, but they will be laid with trouble to the architect and danger to the building."

you dont need DO in Hempy buckets because the nutes arent totally in nutrient solution, they are in medium, this medium contains air, therefore air get to roots via diffusion because medium contains air, last two inches contains nute solution that is constantly being taken up the plant via a mechanism known as the transpiration stream, therefore constant movement of nute solution = no stagnant water. when a plant is dry and goes floppy it needs water because turgidity is the mechansim that keeps a plant stiff.
A DWC needs moving water so DO occurs in the nute solution so roots get oxygen via diffusion otherwise if the water was still the roots would use all that o2 in no time causing anaerobic respiration.

Hope this helps.

 

[messn'n'gommin']

opinions are like assholes .... everybody has one . thats not to say either of you are right or wrong . but i'm right in the middle tryin to figure which way is best for me . this is my first hempy run so i'm tryin to get it dialed in . my soil grow was watering every otherd day & close to every day towards the end . so this is what i am inclined to here as it worked great for me recently . but hempy is different than soil so i'm not sure its right . i'm 3 weeks into veg ... one more week till the flip . i have been feeding every 2 to 3 days depending on how dry the mix is down to my second knuckle .the last week seems like they want more watering ...every other day at a quart per plant with little to no runoff .i should also add that i water in 16oz increments ... meaning i'll give them a 16ox cup of water/nutes to each plant & wait 15 minutes before i give the second one , looking for runoff before i give more . i'm up to 2 1/2 cups every other day now .thats 40oz per plant . but i feel like cuz this has a rez maybe i shouldn't be watering as often as i do .
are their benefits to not watering so often ?i know in soil you want to let them dry out so the roots will expand looking for water ... but with the hempys ...once they hit the rez ..search is over . they just expand in the rez . or maybe i have that wrong . dunno

Off-hand, I'd say the amount the plant wants has to play a small role in how much solution you use. After that, I say that is about right for approximately a 2-1/2 to 3gal (about 12L) bucket.

Personally, I'm using four, 12L black plastic office trash cans with about a 75/25 ratio of perlite to vermiculite and watering with about 1L of solution about every 3rd day (lol...I say about, because I'm not smart enough to split hairs). As an experiment I went seven days after one watering (about 1-1/2L until runoff, for max capacity) before the leaves showed the slightest amount of wilt.

And yes, yield sucked! But, that wasn't the reason for the experiment. The test was to see just how long i could go before an apparent physiological response. If your plants are soaking up watering in two days time...I say give it to them!

Wow, What a bunch of internet dick waving goin' on here. I dont wanna play, i gots a pinner.

What Im more curious about is the osmocote mentioned a few pages back. search didnt help me much but then again im not as smart as some. whats the generally accepted application rate in a hempy? i have access to a giant 50lb bag of osmocote classic from the school nursery (14-14-14) but cannot read the label. is it generally just mixed into the substrate or top dressed? always trying new things...

 

[Japanfreakier]

Are we to assume that the addition of perlite in that wet zone give us an advantage?

Well you might have to assume but I know. Once again experience trumps all.
