Hydroponics is a method of growing plants without soil, using nutrient-enriched water instead. This technique can involve various inert mediums like sand, gravel, or perlite to provide mechanical support for the plants.


The Hydroponics Reddit

Hydroponics - a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to byproduct from fish waste, duck manure, or normal nutrients.

Pothos that was in hydro recently transplanted to fishtank and now dying - any advice?

I also posted this to r/pothos but I think I may have better luck with advice here. Also, I should note that the fishtank does not have fish yet! It’s brand new and should be cycling.

Hydro Pothos in fishtank losing leaves like crazy - any ideas why?

I have a golden pothos that I bought this past March, and I’ve had it growing super well since then. I put it in water and mixed in some liquid fertilizer, then eventually moved it to a larger container with an air stone. It was growing like a weed and I was super happy with it. Last week I decided to move it to a new fishtank that I’m setting up, and also to separate out the smaller stems from the larger ones and put them in separate net pots(the larger ones were overcrowding the small ones, and they weren’t growing well because of a lack of sunlight). The tank looks great, and now they have more room to move around, but unfortunately I’ve had to pull off 4 yellow leaves from the larger plants this week, and another leaf is already turning yellow. :((

Here are the factors that I think could be relevant:

  • I used topfin water conditioner to remove the chloramines from the tap water before filling the tank - this is allegedly plant safe

  • I used all purpose/play sand from lowe’s - I throughly washed it first, and other fish keepers do and recommend this, so I doubt there would be an issue with it, but who knows

  • I added topfin quick start/bacteria to the water

  • I put in a flake of seachem marine fish shrimp flake, which I use for my saltwater tank, to produce ammonia. At the time, I didn’t think there would be enough salt content in one flake to matter, but now I am wondering if I was stupid, although the yellowing did start before I did this.

Another thing to note is that the roots are developing a weird, possibly bacterial or fungal, fuzzy translucent film on the ends (I know it’s normal for roots to have some fuzz on them - that is NOT what this is, and I can post pictures tomorrow).

The plant is getting more sunlight now than it was before, so I doubt it’s a lighting issue. It shouldn’t be getting so much that it’s killing it though. There is an airstone in the tank, and it’s directly under the roots, so oxygen should not be an issue. It also may or may not be relevant that all of the yellow leaves are centralized closer to the roots of the plant, while the leaves further from the roots/further down the stems are fine for now.

I really love my pothos and I do not want it to die! Please help if you have any idea what might be wrong! Thank you!

Quick question about elbows vs 1 inch pipe with an end cap.

Hey everyone- quick query. I am building my own hydrophonic system. Its on a triangular pod like structure. I am using a cylindrical PVC pipe with 3 inch diameter. question is in order for me to connect the upper pipe with lower one, all DIY videos show an end cap with a 1 inch connector pipe going in to the lower pipe. Anyone used two 90 degree 3 inch elbows instead ? Any pros and cons of one system vs the other. Where I live both alternatives roughly cost the same.

Thanks

Ebb-Flow Timer

I'm sure this question has been asked and answered many times, but I can't find it. I need a timer to cycle a water-pump 3 times a day. My Google-fu fails me. Please help a brother out.

Any tips on germination in the fall?

Having trouble sprouting any seeds, tried mostly leafy vegetables lettuce, basil, kale. Tried every method I could find on youtube, got a few to germinate but didn’t grow any further than a tiny sprout out of the seed. I know it’s the wrong time for a seed to naturally germinate so wondering if there’s any trick to it, this time of year. Thanks.

I live in Southern BC, Canada btw. Average temp is 8C-15C and can be pretty damp. Day is getting shorter. But indoors I have a few T5 lights, heat mat, humidity dome, etc.

City water or distilled?

Our municipal water is pretty hard. Should I use only distilled water only or is it alright to use tap water in the Aerogardens and Kratky Jars?

Rockwool cubes or shreds

Hello,

i have acquired a garlandtray and an autopot easy 2 go system to flood it with. The flooding happens via pressureexchange, when plants have emptied the tray.

I reasly want to work with stonewool on it, since its super clean and practical. However i am not sure, whether to use a cube or a mixture of stonewoolshreds and clay pebbles, since i am not sure, whether a block, sinply sat on the tray could maybe retain too much water inbetween cycles or not, since there is always a little bit left in the tray and stonewool is able to soak up alot.

Do you have any experiences and or ideas?

Thanks alot :-)

What is going on with the bottom leaf of my beit alpha cucumber?

I'm using distilled water, General Hydroponics FloraNova Grow every two weks, and extra CalMag weekly. It's a new plant with just a handful of true leaves so far. It's in an Aerogarden farm unit by itself, but next to another unit growing peppers, celery, and rosemary.

Pictures in comments below.

Dwc hydroponic question

1st grow, in 4th week of flower. Changing the bucket to a fresh bucket of water and nutrients is increasing harder to do when using netting for support. The plant needs to be raised to change bucket. I'm afraid I'll damage the plant when lifting the net basket from the bucket. How do others handle? Thank you

Outdoor hydroponic and mosquitoes.

Hi, total noob here so plz don’t chew me alive lol. I have been thinking about starting an outdoor solar hydroponic DIY. But my backyard gets lot of mosquitoes even when I make sure there is no still water around. So I was wondering does mosquitoes breed in the water container of the hydroponic setup? Has anyone faced this issue? if yes how do you deal with it, in non toxic way?

Do air pumps clean water?

This pump is for an ice bath but I'm wondering if it is just an air pump and air stone? It claims 'The Ozone (Oxygen in the form of O³) kills bacteria and viruses instantly on contact and leaves no waste products that cause irritation or cloudy water like chlorine'. Is that what air pumps fo or does this have something else in it that cleans the water?

If I use a Ph lowering solution to bring the Ph down to 7 should I still buy the hardwater version of FloraMicro?

So I'm starting my first hydroponic grow soon and I'm in the middle of purchasing the necessary nutrients needed. I've settled on buying General Hydroponics FloraMicro, FloraGrow and FloraBloom.

However I've used a PH measuring device to check the PH of the tap water in my apartment and it has a PH of around 9. So I assume I need to use a PH lowering agent but I'm wondering should I buy the hardwater version of FloraMicro regardless of whether I use a Ph lowering solution? Or should I buy the softwater version?

Any helpful information would be appreciated. Thanks!
