Right. So hey everybody, Hush agrees with me. Don't use aquarium heaters unless they are submerged in water- they WILL explode!

Hemp coco ftw
i am wondering about the benefits of a hempy being fed with recirculating...
it got me thinking, especially since i just switched from hand watered coco hempies to coco PPKs.
A Hempy is a great thing, but one drawback is that the Perched Water Table (PWT) is higher than in a normal bucket due to the hempy reservoir IN the bottom of the bucket. if your hole in the side of the bucket is at 2" as they usually are, your PWT is permanently 2" higher than if you did normal top feed recirculating using a normal bucket (draining out the bottom)
The higher PWT will serve to make less coco available for roots to grow in. For hand watering, the benefit of the coco not drying our so fast and causing more rapid salt buildup is worth the higher PWT
but:
but you are never going to get dried out if you are recirculating (unless you feed only a couple times a day) . OF course with a recirculating coco system, we tend to feed enough times a day that the coco NEVER has salt buildup...
SO, i am interested to know what other hempy benefits are there that make feeding a hempy with a recirculating system worth having a higher PWT? I cant think of any.
For years I just put 1L pots 100% perlite on big trays and filled em enough to get a good PWT (?). Worked kind of like a hempy but the tray was an extra big rez. Easier to control PWT that way.
And it's lazy as fuck + gives you a bigger rez. 12/12 from seed 150w HID 1L pot 100 perlite. Only Hesi bloom hydro. Perpetual 25 plant wardrobe sog. Boom shiva.

Its not higher than a normal hempy although when feeding it acts like an ebb flo with hydroton. You have to run on a timer this way as they ebb and then you let them drain with the 2 inch pwt in the bottom. If you dont run on a timer they will overflow all over the place and the plants will move all over the place not good especially if you have bigger plants! I only use a 20 gallon rez and can leave it for 5 days unattended. With a bigger tote and rez capacity they can be left for longer over a week with the right nutes. I run PBP with botanicare sups....and ro
i didn't say it was higher than a normal hempy, i said every hempy has a higher PWT than a normal container (hat with holes in the bottom and no internal res i the bucket with the medium))
your PWT isn't at the top of the water i the hempy res, it is 2" higher than it would be without the hempy style bucket. it is as high as capillary action will allow it to be (for a given medium) , and having 2" of water in the bottom raises it two inches MORE.
so basically you donated about 2 " MORE of medium (the height of the res in the hempy bucket raises the PWT that much). but it isn't buying you anything because you are already keeping the buckets more most than the res in the hempy ever could.
but hey, if you get good results =, who cares.
You mean I ought to drill out the bottoms and drain all the way out every flood leaving no retained water in the bottom?
I tried that the second run on this system and it sucked. Its pretty well tweeted just needed a better pump which I hope I found the other day. A Little Giant msp-5 1200gph.
The thing with 100% hydroton is you can water it 24/7/365 no worries, but I let it dry out to get more oxygen to the root system. It classic Ebb Flo tables with hydroton it is common to flood 3-4 times for 15 minutes during lights on which is why I settled on this way. Although my first run I ran 24/7 for veg and first 3 weeks until they started overflowing and floating out of the buckets.

I haven't heard of PWT before but I get it. As a bottomfeder I let my plants sit wet for days. Both passive hydro and soil. Then the potsize decides how much external rez I get. PWT explains why it works so good.

May look into doing this
heres another thread specifically on coco hempys which is my preferred medium.

peace, bozo
I just made one with a 3/4 gallon container and straight perlite. Now I have this thread in my post feed, I will update here with pics how it does.
If you are recirculating it, it's not a Hempy bucket, it's a Dutch bucket.
Dutch buckets are built as many ways as you can imagine, bottom drain to side drain.
A Hempy bucket relies on the daily draw-down of solution, to keep the plants pythium (root rot) free, and growing pretty briskly no matter what the temperatures are.

Numerous feeds per day?! That sounds absurd... I water my hempys once every 3 to 4 days and the photos in this thread that I've posted prove nothing to worry about root rot. Seems to me yall are making this harder than it needs to be and wasting water and nutrients simultaneously.
Good idea. Everybody seems to be trying to build a better mousetrap, which I can dig. But just go over to the coco hempy thread, and read all the bitching and complaining. "I can't get my ph right". "My shit keeps drying out too fast", etc.
None of that with original Hempys, just saying.
We call em Ebb n Gro's bro!
