a ppk for a 6 plant limit

[Snook]

I think you got that backwards

NO, HE DOES NOT.

running at 90 minute intervals or 2 hrs to run its cycle ??? the pump is still running at full power but you got it is restricted so pump is working over time with back pressure and over heating possibly creating heat no other way your going to shake it
the feed lines are not cracked wide open there pinched back so it floods gradually if i am not correct
if it wasn't i am sure that pump force would blow the medium all over the place so i am guessing like a pressure washer
I am just trying to trouble shoot prior to deciding on what mag pump i want to purchase and being more efficient for instance
instead of 1 pump running at 1800 gph at 4 foot of head for 250 watts where i could go two 1000 gph units with same head for 180 watts 28 percent less power consumption and have same flow
if anyone is going to do this or try guessing it would be best to have all parameters in check including water temps i also read D9's water temps where on the high side would he see better overall growth if water temps were in check i bet he would

So this is the dilemma i am in and leaning more to 2 pump set up thinking its a win win meaning i never have to worry about single pump failure and if i decide to go away i can easily run one pump with even more cost savings right ??? or pull one for service never having to worry about losing circulation

the pump, runs for 90 second every 1-3 hours, DF. you really didn't read the thread completely, did you, tell the truth. Or maybe English is your 2nd language. if that is true, get a better interpreter.

and like they say above (and 'they' are correct') this isn't DWC.
water temps and their ability to retain O2 is not relevant to the PPK. DF, continuing to whine that you are correct, is indirectly saying, D9 doesn't know what hes talking about and he developed the PPK. it sounds trollish.

EDIT: sorry i'm not as 'kind' as D9 was in his last response.

Looking forward to seeing some plants. Switching things up is always fun.

I think you guys are jumping on Dr Fever to much. A poster had posted that warmer water holds more oxygen than cold water. I corrected that just before Dr Fever did.

It is true that the PPK does not rely on dissolved oxygen but more on the flooding to push out stall air with a flood cycle and bring in fresh air when the flood ends and drains back. This does not negate bad information. Like many here I learn a lot from threads that I may or may not use that style of grow. This is why it is important to have accurate info.

Dr Fever was just correcting someone's error.

Ty sir i am just trying to get all this down to a tee it gets expensive on power seeds or what ever if it fails on you 1/4 way or half way thru
To my understanding this is like flood an drain with a wick for emergency purpose just in case power goes out ok
Here are some questions i got and i think its relevant when this system floods its in deep water cult So even though you are now in deep water culture mode your plants are not receiving the amount of air and oxygen as if they were in a deep water culture system. The reason why is a deep water culture system has air constantly pumped into the reservoir 24 hours a day in which the roots are submerged. During the ebb cycle, or draining of the tray or bucket, air is now pulled down into the grow media supplying oxygen to the plants. At this point until the next flood cycle the roots again are being deprived of fresh air and oxygen. even tho your using floor dry or what ever is the air getting to root zone fast enough

2nd is your water in lower res below plant now stagnant water so is this good to wick back up if it has no 02 in it ??? No nutrient absorption occurs at the root zone unless oxygen is present. At a molecular level oxygen is required to transmit nutrients across the cell wall and into the roots. So, when you hear someone say they put an air pump in their nutrient reservoir to keep the plants from drowning, that is not exactly true. An air pump is placed in the nutrient reservoir to keep the plants from starving. is this the reason for the air gap ???? and if so how does it get aerated into the water is that air stagnant air

3 what about pathogens contaminating everything

Please don't come and attack me i am just thinking for me adding air injection might be a better choice for res an lower res hell even in medium

 

[Ichabod Crane]

The air gap is used to move the perched water table up and down. By lowering the perched water table you remove the flooded part of the pot so that the roots do not sit in stall water. The wick then can be used to bring water up into the pot if your plant is drinking a lot or lowered if it is not.

As for the oxygen in the root zone there is two ways to get it there. One is by the flood which forces the stall air out. The second is by using a wide pot that is shallow. Being shallow allows the air to penetrate from the top down.

I am not a expert so maybe some one can explain it better.

Oh please for a person that tries to Demean me and not one journal or picture ??? could you be so kind to post your ppk grow for all of us to see ... in your tent ????
It appears you got it down pact , i have in no way indirectly say D9 doesn't know what he is talking about,
I am looking at the pro's and cons to this system every system has them ???
and for your info i am perfectionist so i want every bid of info and be able to understand it perfectly, as this is fairly new to me
from being a Soil grower with multiple rooms going its time for down size and change.

So started a thread on my current grow in its early stage tho. seeds just cracked
i will be using under current DWC as well plan on throwing a few in a ppk grow room
so if you got any positive things to add in this thread then great if not then Sit your ass down and learn also only thing your doing is making a ass out of your self coming at me clown

Dr fever if you take the time and read the old ppk bible, you will learn everything you want to know, many things you wouldn't have thought of, and the difference between shit and shinola. Just read like 10 pages a night. Its cool to see the evolution of the device.

Reading that thread improved the way I think about growing in many ways.

don't dab naked! especially over your "lap" while sitting.

mr happy now has a new "birthmark"!

looks kinda like a fly!

To my understanding this is like flood an drain with a wick for emergency purpose just in case power goes out ok

Essentially you are correct. The wick serves three purposes however. 1. it's a wick, obviously. 2. it's a drain for the flood cycle. 3. allows you to move the perched water table out of the upper container.

Here are some questions i got and i think its relevant when this system floods its in deep water cult So even though you are now in deep water culture mode your plants are not receiving the amount of air and oxygen as if they were in a deep water culture system. The reason why is a deep water culture system has air constantly pumped into the reservoir 24 hours a day in which the roots are submerged. During the ebb cycle, or draining of the tray or bucket, air is now pulled down into the grow media supplying oxygen to the plants. At this point until the next flood cycle the roots again are being deprived of fresh air and oxygen. even tho your using floor dry or what ever is the air getting to root zone fast enough

The flood/drain of the system should take at an absolute max of 5min to complete (I personally shoot for 2min. 1 to flood, 1 to drain). In either case the roots aren't submerged long enough for the o2 content of the water to make any noticeable difference in growth. During the time between the floods you have two things working in your favor 1. the PWT is moved down into the drain/tailpiece. This allows the entire upper pot to be at the ideal air to water ratio almost immediately after being flooded and maintains that ratio between floods due to the wick action and constant water level in the lower bucket/s (that is the reason for having a float valve top off your main res). 2. Using the shallow 7 gal. containers assists with lower the PWT, as well as helping o2 exchange with the atmosphere. Both due to the increased surface area over a taller container of the same capacity. Add that together with regular floods, and o2 shouldn't ever be a concern.

2nd is your water in lower res below plant now stagnant water so is this good to wick back up if it has no 02 in it ??? No nutrient absorption occurs at the root zone unless oxygen is present. At a molecular level oxygen is required to transmit nutrients across the cell wall and into the roots. So, when you hear someone say they put an air pump in their nutrient reservoir to keep the plants from drowning, that is not exactly true.

All the water in the system is regularly aerated and remixed as part of the flood cycle (very similar to how a flood/drain table works). A majority of the o2 your plant will see/use in this system is pulled from the atmosphere, and very effectively at that . So it's not necessary to aerate the water in the res. Certainly wouldn't hurt anything, but I seriously doubt you'd see a noticeable improvement.

An air pump is placed in the nutrient reservoir to keep the plants from starving. is this the reason for the air gap ???? and if so how does it get aerated into the water is that air stagnant air

No. The air gap is only there to control the height of the PWT in the tailpiece. In the event of power failure the tailpiece will continue to maintain whatever water/air ratio you have it set for. Essentially the roots draw in water/nutes, and through capillary action air is pulled from the atmosphere, and water from the wick. It's not perfect, hence the use of floods during normal operation to supercharge o2 levels, but it will keep your plants alive and reasonably happy during a power outage.

3 what about pathogens contaminating everything

Doesn't seem to be an issue due to design. Not saying it couldn't happen, but if the system is being operated as prescribed the chance of getting pathogens is very low.

Please don't come and attack me i am just thinking for me adding air injection might be a better choice for res an lower res hell even in medium

Most of us are here to help.

This thread is so full of info from actual experience. I learn so much in this thread.

Mostly that dope smokers do in fact do stupid things.

Dr. fever,

the main thing u need to grasp is that the roots don't, or aren't supposed to grow down in the bucket below the planter. So adding air to that water does nothing essentially. also that's why water temp, and water pathogens are not a problem as well.

"I" am making an ass of myself?

If you 'are' a perfectionist you would have read the original PPK thread. It is obvious you didn't.

Help can come in many ways DF and it has. my frustration with you is you're not listening. this isn't DWC!

as for pics, KMA!
