Please Help?! Hot do I deliver Nutes in my limited space.

[Dogenzengi]

Hello and thanks for reading,


I am working in a space 56" high.


With my light hoods I have about 44" to the floor.

I have about 24 sq ft of floor space broken into two areas.


I would like to use two drip irrigation systems but it will have to be the same level as the reservoir.
(on the floor for both)


how can I pump the liquid back to my reservoir from my tray?


peace,
DZ

Thank You Tbird!

SOOOOOO SIMPLE. Use cpvc for the drip system(trust me cpvc works best) Buy a 50-80 gallon fountain pump from lowes($17) and a 15-20 gal rubber made container, or whatever size will fit your space. Fill your tub with your water and nutrient mix then place the pump is the tub. Buy some 1/2 in rubber tubing to run from the pump to the cpvc up to the lid. Drill however many holes in the lid the same size as your net pots, put your net pots in the mark when the cpvc tubes cross the pots, drill holes in the cpvc(three holes to each pot) then connect all this with elbows and pvc cement. Turn your foutain pump on the water will run to every plant then drip back into the container!!!! Easy as can be and produces great results as you can tell from my pics.View attachment 2673530View attachment 2673531

Good idea Gtran, thanks for the pix.
i will need a more shallow container because of my low ceiling.

can a plant grow to finished buds in a 6" net pot?

I can fit Four systems as you describe.
I would probably have 6 plant per container like you.
also so I can leave them in rock wool surrounded by clay pellets.
Grow From clone placement to Flower in the same place.

I bought some drip irrigation parts, your idea is so much simpler!
thanks again!

peace,
DZ

I start and finish my clones and flowering plants all in 5in net pots. The reason these are large enough is because when the roots grow in a hydro system they are growing down towards the water/oxygen/nutrient rich water which means that the roots wont spread until they hit water level which is why buying a big container is a good idea. Net pots are the way to go, i use the same size for every grow because its easier to move them into different spot. I recently started putting all my germinated seeds in 1 in rockwool cubes and after the first few sets of leaves grow, i bury the rockwool cube in hydrton and let the plant sprout through. Also, the more oxygen you can get into the water the better, im using a double pump with 2 4inch air stones at the end!!!! Ive had situations where the plant roots literally wrap themselves round the airstone they like it so much!!! Let me know if you need anymore help.

I dont think you are fully understanding how DO (Dissolved Oxygen) is delivered to your root system. Root systems are incapable of utilizing oxygen in its gaseous form (What comes out of your air pumps). Air pumps are used to break the tension of the surface above making it more turbid, allowing the water without DO molecules to come in contact with the oxygen rich air, thus increasing DO percentages in your water culture. The extra molecule of oxygen can only then be utilized by the root system. Your roots are not growing around the airstone cause they like it, and actually greater DO percentages can be achieved by simply waterfalling the reservoir mixture over and over into itself (Which is why Undercurrent can be run successfully with out the use of airstones at all) I am glad that you are having success with your setup, but would you find it easier to manage reservoir temps by putting your pump inline rather than having it run 24/7 inside? Just a suggestion because the OP is asking for an idea for how to best manage that space... I would strongly recommend looking into recirc DWC otherwise known as Under current where the reservoir is at the same elevation as your containers. My 2 cents, goodluck~S0uP

His question was returning the nutes to the rez. This video does not address that, it is a simple DWC bubble system that accounts for evap.

My system PUMPs nutes from rez to the plants in a tube/deep tray. You can use another, smaller, pump on a timer connected to a float, to return to the rez.

Here's cool system I put my spin on, that can be run either way. I have the space to gravity drain back to rez, though. Airstones are in the rez

Great Answer!
I will be doing undercurrent DWC, I hope it is OK for a beginner to use.
peace and much thanks, oo soup oo, You are my Obi Won!

Well you seem to know your stuff about dissolved oxygen but the plants clearly know where the oxygen is coming from. I have yet to have my res temp go over 75 and im having great results with my system. I am concerned about how im going to keep my res temp down when i switch to a HPS bulb. From what i understand, res temp should be between 65-70 degrees when flowering? Any tips on keeping the res cool would be greatly appreciated.

Again, the plants DO NOT have the ability to absorb the oxygen gases coming from your airstones, whatever sign you are seing that they know oxygen is making its way to the surface of your water culture via the airstones is an illusion I PROMISE. That isnt an argument Im willing to pursue as you have the ability to google it for yourself. Nonetheless, I am glad you are experiencing success, truly I am, are you running non stop H2o2 with your res? I saw in another thread you were asking about the setup of an 8" inline (you can Pm me if you didnt get a satisfactory answer) but that should help maintain some of the temps with your HPS bulb. Regardless I would set up your pump inline as suggested above and hook up an igloo DIY chiller at the same time. https://www.rollitup.org/do-yourself/453926-25-diy-dwc-chiller.html

Something like that is cheap and very effective believe it or not. Goodluck.

OP, I got your PM regarding the setup of an inline water pump and recommendation for model. I dont DWC or undercurrent myself (Im just interested in the science behind it) and would want you to get the most out of your investment. I suggest you post your query in the water culture forum here or look over at thc farmer as they seem to have a higher population of undercurrent users. I would encourage you to do extensive research before jumping in to UC, it requires full time attention and a good understanding of pH, PPM, DO, and plant biology. That being said when dialed in can produce some of the most exceptional results for MJ cultivation. I just wouldnt call it beginner friendly. Goodluck. ~S0uP

that vid is of a recirculating DWC system, the pump shoots water to the buckets, which are all plumbed to the rez, the water "recirculates" as the pump runs.
