Back when I was a member of a forum known as HG420 I met a guy named Hempy, this was his method and I have used it to great success ever since. If anyone here remembers HG420 you know how exclusive and how many of the worlds best growers frequented there.

The biggest benefit of this method is.......it's virtually free!

To make a hempy bucket is simple, all you need to do is this:

Get a bucket.

The size of the bucket can vary from 1gal(4lt) to 5gal(20lt).

Hempys' preferred size is a 2.5gl bucket, I use 5 gal for monster plants

Drill a drain hole in the side of the bucket about 2 inches from the bottom.

The drain hole should be 7/16". I've had better luck with 1/2" and larger perlite

The grow medium is perlite/vermiculite. I generally nix the Vermiculite as I notice it slows the rate at which the roots hit the bottom of the bucket due to the wick effect, but it makes things a little less high maintanence for the first week or two while waiting for the roots to make contact.

3 parts perlite to 1 part vermiculite.

You can use volcanic rocks (Hydroton) but the perlite/vermiculite is the preferred method.

Once you have your seedling sprouted fill the bucket with plain water every day until the tap root has reached the standing water that always remains in the bottom of the bucket. this will take about 10-14 days after the bean sprouts. If you use clones, plant the stem in the middle of the bucket as it will shorten time for roots to hit the bottom, however you loose space for the root ball by lowering the stem, if your in rockwool or anything like that what I like to do is bury the rockwool about 1" from the top of the perlite so it has a little support on the stem but allows the most space for the root mass, upon harvest you will be amazed with the size of the root mass! Also what I've been tending to do recently is water directly down the stem of the plant until you know it hit bottom, and trust me you will know when it hits the bottom, I also use PH'd and Nutrient filled water every other day w/ root stimulates, I've noticed this tends to speed things up but you don't want to let the salts build up in the bottom so when you water with fresh water use alot to run off the standing water at the bottom of the bucket.


Completely fill the Hempy Bucket with plain water, every two-three feedings. This will stop all the nutrients from going stale and building up salts in the bottom.

Use water that has been open overnight to allow the chlorine to escape, unless you can afford to buy filtered or distilled water..

Fill your water bucket or whatever you use to water with JUST water, no nutes, or PH until the following day, Add the nutrient solution to this water bucket and then adjust the ph to 6.0 For best results use an accurate ph meter and follow the nutes mfg reccomended amounts very carefully. Use precise measuring devices to make your nute solution.

Once your roots hit the bottom you will notice a much faster rate of growth and at this point is when you want to begin full strength feeding always, I like to add water/nute mix every 2 days, however I never let it get dry, you could water in theory every 5-7 days depening on the feeding rate of your plant, when I water I move the bucket to a utility sink or drain and I add until there is a little bit of run off allow it to level out


The strenght of your nutes depends on several factors such as how much light you have, humidity, CO2, strain your growing. You will have to use judgement, If your plant looks under fed or unhealthy add more nutrients, generally your mfg feeding schedule is going to be the safest bet without over feeding or burning, If you notice what looks like burnt tips on your leaves your under feeding. also look up plant deficiencies and get a feeling for what different defiencies look like since your medium isn't soil it will provide 0 anything for the plant. make sure to have a good line of nutrients, I always use 3 part nutes, Veg, Bloom and Micro and have had good results, I also use additives like Superthrive and other planet essential vitamins.

thats about it. Its a pretty simple way of having a passive hydroponic grow, I only use organic nutrients with my plants as well, I have had extremely impressive results compared to soil grows of identical clones side by side and I haven't looked back since.

i am very happy that you brought that over to share. i have often thought about collecting some of the most informative pieces i have read over the years and posting them here as well. this is definitely one of those threads. i have never personally owned a plant in a hempy but i know tons of people who do and it is a 100% proven and extremely simple and effective way to grow.

rumpleforeskin's bubblebucket DIY thread from GrassCity is a must have on this site as well. i will post that later today.

Exactly, we need to archive everything and anything we can on this site! Alot of people are just begining and any guidance I/we can provide people will help weed out all of these quality issues. Growing high quality meds is a simple thing and all to often people don't want to search far and wide for the info needed!

So let me understand this... A hempy bucket is a 2.5-5gal bucket with drain holes 2" up from the bottom to create a small rez.. correct..

"I generally nix the vermiculite." So despite the medium being described as 'perlite/vermiculite' you grow in 100% perlite, 1/2" or larger?

i am leaning towards doing the bubble buckets after a couple more cycles. But the hempy grow method may be a nce intermediate step. I'm gonna keep my eyes on this.

hempy's are no joke.
if dialed in correctly, you can seriously get stupid big plants.

i took a hempy bucket to the Holland CC last week just to show folks what they were and how they worked,the other members had a hard time believing that something so simple could grow the meds.i showed..lol..i may have gotten a few converts and for the Posted Imagenewbies nothing could be easier...i'm a hempy bucket kind of guy...lol..zzb

i love hempys.

really i do.

they are so easy its dumbproof.

for a beginner just starting off, or someone making the transition from soil to hydro, i highly recommend making a hempy to get your feet wet.

very user friendly.

That is my ultimate plan- I really want to step away from soil, and go Hempy all the way... Soon!! :thumbsu:

Wow this thread sure woke up...

So let me understand this... A hempy bucket is a 2.5-5gal bucket with drain holes 2" up from the bottom to create a small rez.. correct..

Yeah, I'll bring pics over in a few days, just waiting on some supplies for my room before I bring all the messy stuff upstairs in my house :lol:

you got it sub.

but jipo just started 12 in hempys and i expect results jipo :)

and pics to add to this DIY. if you need help, just holler and i will get them added for you.

You know I'll be pic heavy, I don't have my DSLR Camera anymore just a Nikon P100, but it'll do the job :)

I will be taking a seat in the front row for this one.. I've been looking forward to this for a very long time! Yay Jipo!!! :goodjob:

Thank you!!

"I generally nix the vermiculite." So despite the medium being described as 'perlite/vermiculite' you grow in 100% perlite, 1/2" or larger?

Yeah the Vermiculite will make it easier for your plant to drink before the roots hit the bottom, however in my experience the roots don't search for water as hard and hit the bottom as fast. Vermiculite has a wick effect and stores water, perlite does to an extent but barely at all.

i am leaning towards doing the bubble buckets after a couple more cycles. But the hempy grow method may be a nce intermediate step. I'm gonna keep my eyes on this.

I'm going to switch after my 12 strain grow (or hopefully 12 if they all pop) however I have a lot of hempy supplies and figured I wrote the tutorial I might as well do a grow journal of them :)

hempy's are no joke.
if dialed in correctly, you can seriously get stupid big plants.

:) this.

<<< REALLY wants some stupid big plants!!! :D :D :D

Easiest method to get them is this, just follow along I should be adding a nice bunch of photos on sunday as long as mr_smith comes over and helps lends a helping hand

Give this man a round of applause. Thats a fine fine grow you got there.

Best advice ever. If you grow soil, this changes nothing but your medium, you water it the same, treat it the same, end up with hydroponic results.

I like dumbproof... but sounds like you gotta flush it with water/nutes by hand everyday? could you do a drip on it? seem an idea this good could be made to be near maintenance free with a rez, drain in the floor or good catch basin, like a non recovery NFT. also I don't get how to fill it up with water. V V

"Completely fill the Hempy Bucket with plain water, every two-three feedings. This will stop all the nutrients from going stale and building up salts in the bottom."

Guess I'm not dumbproof.
