Has anyone successfully used organic liquid nutrients like The Foop fish poop based line? I’ve tried several times to go organic but I get clogs and bio film buildup like crazy. I’m going to switch back to salts if I can’t get it to clean up soon. Any suggestions?

At what point do I take off the stickers for this system I just got?

I'm currently running a one-shelf rail system for lettuce based on the designs on https://www.simplegreenshydroponics.com/, which functions kind of like a hybrid NFT/RDWC system of sorts. I am designing an upgrade plan to expand the system. So instead of one shelf with 2x 4ft rails, I'll have 3 shelves with 3x 4ft rails each. This will result in one shelf with 68 plants in the 2nd thru 5th weeks of growth, and 34 plants on the top 2 shelves in their final 6th and 7th weeks of growth.

I'm trying to decide whether to run three pumps -- one to supply each shelf -- or one pump to the top shelf, which then drains to/through the middle shelf, then to/through the last shelf. Running the system in one loop would essentially be 36 linear ft of planting space.

So my question is whether supplying the entire system with a single pump would be alright, or cause nutrient/oxygen issues for the middle and bottom shelves?

I'm starting some tomatoes in kratky jars with plans to move them to dutch bucket when I get time to build my system (hopefully the coming weekend). I've been topping up the nutrients being careful not to overfill and drown the air roots.

I figured since the jars were just temporary/short term I wouldn't need to bother keeping light out, unsurprisingly I have some algae growth. I read a bit of algae won't harm anything but the leaves are going brown (even new growth is dying back from the leaf tips).

Is the leaf issue likely caused by algae? Should I treat with hydrogen peroxide?

FWIW I'm using masterblend full strength, ph down adjusted to 6.0. EC=2.0.

Hey everyone first post in this sub. I’m making this 5g reservoir for a drip system and I’m stumped as to how I should run the power cord. Ideally I would rather not drill a giant hole to fit the plug through because that ultimately defeats the purpose of a sealed reservoir… am I just missing the obvious here? Cord doesn’t detach from the pump.

Greetings everyone, I have a design in mind, does anyone use pvc pipe? They're good enough for drinking water so they should be good enough for veggies, right? Any other input is welcome. Thanks

Hey all, hope all is well. My problem in the last 4 days I've gone through 10 cases of bottled water. I was just about to order 20 cases even @ $3.00 a case it's still 60 bucks, not to mention 480 empty bottles. R/o system about 2-3000. My tap water is 135ppm with a 7.2 ph. Can I just for the love of growing just dechlorinate like I do for soil.

Hello, i have been growing short day strawberry since january, but until now still not showing any sign of flowering. Given lighting hour around 13 hours per days. Also the leaf grow so big which around 15cm diameter. anyone know the reason for this problem?

Hey all, new to the community and relatively new to the hobby, so I hope I’m posting in the right place. I have a DWC system (~8.25gal) that I recently overhauled to better prevent algae growth like adding better light insulation and a new air pump (there’s a little light bleed into the reservoir but it’s really low now). To further beat down any algae that’s growing I’ve been treating with Hydrogen Peroxide ~45mL every other day (I stepped it up about 2 weeks ago from 30mL). Currently I’m learning the hobby with some simple herbs like Dill, Mint, and Cilantro (the others never sprouted 😔). Im hoping ya’ll can answer some of my novice questions:

1. Is this an appropriate dosage of H2O2 for my reservoir size?
2. Should I turn the air pump off for a few hours when I treat the water to prevent speeding up the decomposition of the H2O2?
3. And lastly are there any other algae killing solutions I could use?

Thank you! I’m looking forward to what everyone has to say. I’m pretty new to this and I don’t want to kill my plants or have a gross tank in my apartment 🥲

I have a DWC system growing lettuce in my living room. I have a nice quiet air pump but the stones are very loud. Currently they are just small cylinder types that were cheap. I am running 3 of them in separate tubs. The combined noise is too much. It is loud even from our bedroom.

Are the "nano" style stones with a smaller bubble size much quieter?

Are the long style stones (e.g. 20cm long stick type) quieter? I was thinking maybe they are due to less of a concentrated effect of the bubbles.

I know that some people use a venturi type system but the water pumps I have are louder than the air pump - it is the sound of the bubbles that is the problem.

This is the sun shelf 3 that I use at home. Top layers got some tomato seedlings, 2nd top has some dill which is going wild. I've got some kratky chilli, and lettuce germinating below, and the bottom layer is some more chilli, dill and a houseplant!

Looking to do light feeds on semi hydro media that I water once a week. The media completely dries between watering.

Looking to get close to a 3-1-2 ratio but doesn't need to be perfect. It is for cacti.

I am thinking about growing herbs (mint, basil, cilantro, etc) indoors in a hydroponic setup. I found these kratky method pots designed for aerogarden-like seed pods/peat plugs, and was thinking about using some kind of aeration inside the reservoirs- maybe by getting a 4-outlet air pump and some air stones to run into each reservoir.

Is this a good idea, or is it no better than just using passive hydroponics? Is an aquarium air pump and air stone sufficient for oxygenation/circulation, or do I need something more heavy duty?

Hey everyone! I was wondering if anyone had undergone the transition from a home grower to selling your produce commercially? How was that process, and what were some of the major challenges (expected and unexpected)?

I am a student working on a project researching small scale commercial hydroponic farms, and any help on this subject would be greatly appreciated!

I'm a little tired of pH pens/meters and stuff that don't work very well. They need constant calibration without being told when or if done properly, need to be stored properly, cleaned properly etc. they often don't last a long time. The cheaper models are unreliable and not precise.

I'm now trying to make my own pH tester and I want to know 1) if there's genuine interest 2) what would make a high quality pH pen ex. Precision, user interface, Bluetooth, EC, Temperature compensation,

So if i’m starting seeds in rockwool, to eventually go into cloners do I need to make sure the rockwool is always in contact with the water? Also later when the roots gets bigger around the rockwool does that part still need to be in the water nutrient solution?

We have some nice pepper plants we wanted to try keeping indoors till next spring. So i was wondering if this would be a good cheap solution.

Also wondering if these lights make any noise.

Edit: disided on getting the Mars Hydro TS 1000 Full Spectrum Dimmable 150W LED Grow Light sence its an all around better light with passive cooling.

I've been noticing mold on the walls and inner lid of my garden. I clean it out regularly but within a week It's moldy again. Is there a way to keep it at bay? Its completely inclosed and obviously filled with water so im not sure how to keep it vitilated. It doesn't seem to he effecting my plants but should I be worried? Any suggestions?

(Context)| tried buying agrotonomy ebook of 39$ from India but I don't know my balance was credited but I did not get ebook nor I got a email. Tried contacting them from email but no results If anyone has it can someone share with me
