this is where i plan to put the volume reservoir and maybe the control reservoir if it will fit. I'm thinking about using a longer flatter storage tote for the volume reservoir so i can put oon that wooden reddish shelf ive already got in my garage.
Built what will basically serve as a duct for my passive intake, out of wood
gonna finish sealing up all the cracks in the structure with silicone and put the batts insulation in before slapping on reflective R-tech foam insulation boards.
It doesn't look like much and isn't pretty but i feel like ive spent so much hundred hours single-handledly planning and building this out. My first time setting up a subpanel and fabricating a room and am happy with how its turning out so far. Made some minor mistakes that cost time here and there but im a rookie at building all this stuff and the experience so far already has taught me a lot!
thanks for all your help again d9! i went to home depot today to pick up some 2 gallon buckets while getting some insulation and they dont have black ones, only white. I'll probably just order some online. I can go to lowe's and get the blue ones but i dont like the idea of having lowes logos on my badass ppk modules i have time to wait for itt o come in the mail anyway i need to finish biulding the actual grow room.ok, i've got a little bit better view of your intentions and plans after this last post.
with your plan of two scrog screens with two plants under each you will need 4 plants after all. you will have 8.75 sq ft per plant so you will have to keep them small and flower early.
i am not the right indian to ask about scrogging. i'm about to do it on what is for me a larger scale, 16 plants in 7 gal containers each trained to a 4.5x4.5' screen. i have not done any scrogging in over 12 years. but i intend to top really early and train the canopy as flat as possible in veg before going to the screen. you should go to the coco forum and look at DJM's thread. he is a master at the scrog.
about the irrigation differences. you can fully flood the plant/medium container. this positively drives out all the old gases and pulls in fresh new gas. works great and there is no guess work or experimentation with the volume. full is full.
but it requires large pumps. big reservoirs so you don't starve the pump. large diameter pvc tubing on both delivery and return. multiple valves that must be tuned rather precisely so that you evenly flood all containers at once without any of them overflowing. this approach is more expensive to set up and more time consuming to build than the pulsed irrigation technique.
in the literature "pulsed" or intermittent irrigation is considered to be a subset of drip irrigation. it is superior to a straight drip because you achieve a more evenly wetted medium. i won't go into the reasons for that here but believe me, it do!
to do a full flood in one of the 7 gal containers i use would require about 2 gals of solution because you must have enough to not only fill the airspace but also overwhelm the drain at the same time. with 12 containers that's about 24 gals and it needs to be delivered in a very short period of time requiring all the stuff mentioned above. also you cannot use any media that floats.
right now i'm back to 30 seconds or about 1/2 gal every 90 minutes with the turface/perlite mix. so with the same theoretical 12 plants that's only 6 gals per event. much easier to achieve and much less expensive. the pumps run for only 8 minutes per day.
in the same environment either way grows the same size plant.
in the ppk we are watering the medium, not the plant. we are trying to keep the medium within an ideal band of parameters. so yes you can fire both rooms from the same timer.
basically where im at now regarding ppk research is irrigation. Need to figure out which pumps im going to need for my setup. I think I may want to strongly consider doing pulse feed since you mention its cheaper and you have been running pulse feed lately. I see the simplicity in flood but if i need more expensive pumps and take more time fine-tuning things then i rather look into pulse feeding. Going to read some threads and probably do a little google fu before knocking out. Thanks again brotha
