White Poison - 2 liter Hempy SOG

No run-off, drip pans will be there to catch any excess.

I will refill the big rez as the plants use up the nutes.

The pump will run 2-4 mins a day to fill the hempys.

I went over the theory and math a few posts up and I will see how it works in real world soon.

haha yep on paper it all sounds like it should work well. lets hope that continues once its fully operational. have you put any thought into running bigger hempys? or do the 2 liters keep a good root zone for plenty of growth for the sog?

I dont think I will ever switch to bigger pots for my SOG. It would require more media for every transplant with no benefit other then longer time between waterings.

The two liters grow mothers that are 3 times the size of my SOG clones. And all they require is a double dose of nutes.


I have to actually cut the mothers down in size because if I didnt they would outgrow the veg chamber.

The stuff for my Drip Irrigation has arrived.

Here is a parts list:

1 punch
10 cleanable button drippers - 1 gph
30 cleanable button drippers - .5 gph
10 in line shut off valve for 1/4 inch tube
40 6 inch stabilizer stakes
7 locking end cap
1 locking hose coupling valve
4 locking hose tee
1 locking hose cross
4 locking hose elbow
1 locking hose adapter Female end
1 locking hose adapter Male end
1 Inline hose filter
40 barbed connectors 1/4 inch

50 feet of 1/2 inch and 1/4 inch tubing.



Then my timer, pump, and rez with 2 gallon increments marked.





Its a self contained Automatic Hempy Drip Irrigation system.




First thing to do is cut a hole in the lid of the rez. And use the cutout to make a flap-like door.

Then I can put the drip together.

Done with the sliding flap-like door for the top of the rez.

It pivots on the bolt at the top so I can open it up and dump in water. And it does not close all the way because the water and power lines need the access. I might need an airstone and later a PPM meter too.

OK I put it all together.

The job that took the longest was straightening the 1/2 inch hose.

I had to run it under hot water and bend it back against itself to get it to stop curling.

But putting the drip system together was a snap.


The plants were very dry when I first tested the drip. They drank for about 10 mins before they were full.

Over the next few days I will be adjusting the timer and watching to see how things go.

When I first started it up one of my end caps was loose and I had a leak that scared me but its all sorted out now.

Looks like this will work.

First of all, I have been following your thread since April and this is the most awesome SOG I have ever seen! Are you sure you don’t have two green thumbs instead of one? My next grow is definitely going to be Hempy.
I do have 1 question for you about pH. In your first post under the heading “Water and Nutrients” you state the pH should be 6.0. In post 132 you state “Deficiencies will show up if the pH goes below 6.0” and in post 123 you state “I checked the pH with my dropper kit and its about 6.3 - 6.5”. For clarification, what should the pH of the nutrient water be before watering when using the Hempy method?

Vermiculite is a bit alkaline. So when I mix up a batch of media with 75% perlite and 25% verm I like to PH the Water down to 6.0 for the first week or so.

But for the rest of the grow I feed with 6.5 PH nutes. I find that this range works best for hempy. 6.0 to 6.5

When I mix up a batch of nutes I know that the PH will be right on after I add the nutes. Around 6.5 PH



If the plants are showing any signs of problems the first thing I would do is check the PH of a Hempy reservoir. Tip a bucket and catch some of the run off to test. This will tell you exactly what the PH of the hempy is inside the media.

Around 5.5 PH new growing tips will be yellow. Sign of a lockout. So I never go below 6.0

I added an airstone to the rez and tested the PH

Its where I expected 6.5

Because this is non recirculating zero run-off system my PH and PPM's should be Stable.

I only filled it up with 9 gallons of nutes to start with. Lucas Formula

Drippers in Action !

this journal's just getting better and better
so you just feed them till theyre full and no run off, right?

Well I was feeding them every other day with a full dose of nutes about 9.5 ounces per hempy.

But now with the dripper system they will get half that amount every day.

Zero Run off.

Each individual hempy reservoir will only fill up about half way each day. During summer they tend to drink more so I will have to make adjustments to the timer depending on season and plant size.

Thank you for the clarification Xare. I know different mediums require a different pH and I just wanted to be sure.

I’m in the process of getting ready for my 2 liter hempy grow which I will probably start the 1st of September. I haven’t had a grow in about 12 years so I’m going to stretch my legs with bag seed just to get the kinks out. Today I was trying to drill reservoir holes in the 2 liter bottles when it dawned on me that a soldering pencil would do a better job. I got out my 23 watt soldering pencil, let it warm up for about 5 minutes and started punching holes like going through hot butter! Drilled holes are ragged looking but the melted holes are nice and smooth around the edges. The tip for this size soldering pencil is barely less than 3/16”. Seems like a small hole, but putting 12 of them around the bottom should do the trick. If a larger hole is needed, just wallow the tip around a bit.

Yea that works good, I melted the holes for my two liter hempys with a little steel rod and flames from the stove.

The Drip Irrigation is great. Iam lovin it.

No more hand waterings



Its been quite hot this week, about 90 degree's and the pump has been running for around 10 mins each day so far. My guess is that cooler months will require 5 mins a day. A bit longer then my designed plans but very workable.


The drippers all flow at a constant rate, there are no leaks, no run off.



Here is the Veg Chamber with drip lines that I can shuffle around. /w shut off valves.







The Main SOG lines coming from the Rez.








All the WP Clones on Drip.





Now to see how it does under use and through time.

If something were ever to happen to the pump I could manually water every other day till I get a replacement.

looks good! how far from the tops of the plants is your 600w?

About 14 inches. The light is at its maximum height right now.

Much respect man! Were the buds dense? Smoke report please

Peace and keep up the GREAT work

Yea, SOG Grows are great for dense nugs. You dont get much little wispy bud at all.

Smoke Report:

My first test of a bud was with my vaporizer. I put part of a bud in the wand started tokin. It hit like some of the Hash I have been vaping. Nice thick hits and it lasted a long time in the vape wand. If something is of high quality you can get alot of hits with the vaporizer. Low quality buds will cash out sooner.

The White Poison in the Vape knocked my dick in the dirt. I was seriously proper stoned. Easily the best stuff I ever grown and the best I tried in the last 10 years.


You can tell its a sativa because you wake up and feel your heart get racey, but at the same time you have a strong overall buzz.

The Smell and taste is Spicy and Sweet. Like a peppermint candy. It gets that from the Durban Poison side.

The buds stick to each other alot. I can open up a zip and take it all out in one big chunk.

This is some White Poison Bubble Hash made from the extra harvest leaf.
