what type of air pump can be used outdoors to aerate a system ?

hey fokes,

im looking to start a DWC tote box type system outside and need to aerate the roots with air stones and a pump. Unfortunately nearly all the pumps ive found that can be connected to aquarium hose and air stones are not meant for outdoor use and I don't feel like they can be left outside in the elements . Is there any specific type of pump or brand or something I can use with airstones that can safely be left outside ?

thanks guys!!

slime // sludge caused by general hydroponics PH UP - what to do ?

hey fokes,

pics of what im talking about https://imgur.com/a/rfsorAy

I'm new to hydroponics so go easy on me please lol. I just started a few weeks ago with an indoor sytem and now also have an outdoor tower. my ph has been low so I got some general hydroponic brand PH UP to help adjust it. unfortunately, for some unknown reason, it caused a lot of slime // sludge in the nutrient reservoir, that ends up pouring over the plants and putting slime and sludge on them too... i attached pics at the begging of this post of what it looks like on the plants, i couldn't easily get into the res to photograph that but i have seen it in another system and it looks discolored and streaked with the slime and sediment .

I had thought this might be causing it in the past, but today, i set up a brand new system , brand new water, clean everything, fresh nutrients, no problem, but within 20 mins of adding the PH up, again, everything started getting covered in slime...

i find this pretty weird because i know general hydroponics PH up is extremely commonly used and i cant even find a mention of this issue online, but i have drained my tank, added everything fresh except the ph up, and besides low ph, not a problem with the slime at all now.

I am using dyna grow hydroponic liquid nutrient and city water, with no other additions, but wondering if somehow the ph is interacting with my water or nutrient causing this issue, or what else could possibly be the issue ?

I plan to switch to maxi grow // maxi bloom nutrients soon and hoping this may somehow solve the problem , but i would like to know if anyone has any ideas what may be causing this or solutions to fixing it ? My ph is pretty low and I need to get it up but cant imagine this slime is healthy for my plants and would like to get to the bottom of this or find a way to adjust the ph up without causing this issue...

Thanks every body!!

Vivosun Hydro Kit - How to do a full clean mid grow?

Firsts hydro grow, so I'm still learning <3

It's been about 2 weeks and I wanna do a full water flush and bucket clean, but the Vivosun Hydro Kit has this tubing so it can feed the drip ring up top. I need to put my plant/roots somewhere while I clean the bucket, but I can't really do that because it's all attached as one unit. Outside of disconnected the tubing, I can't really think of a way to achieve this. Any suggestions?

Also, is it even necessary to do a full dump/clean? Or can I get away with just siphoning this water out and putting new water in without a clean? I think I can achieve that without taking the tubing out.

Thanks!

Mold on roots in Gardyn 3.0

Hi everyone. Today I was saddened to discover that all 20 of the various plants I’ve been growing in my Gardyn system have this green mold growing on their roots. I did a root trim/check a couple weeks ago and everything was fine. There is no mold growing on top of the rockwool substrate. One of my lettuce plants is looking limp, but everything else appears fine in terms of observable health. Pictured here are the roots of a cherry tomato plant.

I’m not sure how to proceed. Can I somehow treat the problem and preserve the plants? Are they all goners? How could I prevent this from happening again in the future?

Any advice is appreciated!

A Few Questions Before Finalizing Project

Greetings!

I have recently finished building an outside twin vertical hydroponic system and the water flow, joints seems to work without an issue. (I reside in Central Florida if that potentially helps)

I'm still completely new to the hobby and I wanted to get some tips as far as maintenance and care goes with these systems before I start it up with plants. Honestly anything that comes to mind will help a ton so I don't mess up too badly my first go around.

Things like

  • how often you check for nutrient balance?
  • How do you go about cleaning/sterilizing the system if needed at all
  • Important values to keep an eye on

Real sorry to ask all these questions but I want to get this down right before expanding and making more systems to add to the house

Thanks a ton in advanced and I hope y'all have a good day :)

Will this be ok?

6 red josta berries got here about 4 days before i am ready to plant them. I have them in a 2 gallon bucket with an aquarium air pump. Will they be ok in my garage in this state till the ground is ready for them? I’m interested in trying hydroponics and this is my first project. Thanks.

Is this normal?

I'm new to hydroponics and pretty new to gardening so please don't come for me. Do the roots normally look like this when plants are overgrown? Im assuming it had been tangled in the water pump as the level was not going up despite filling it.

Hydroponic Tower Survey

Hi all! I'm an industrial design student and hydroponics lover. I am looking to create a new hydroponic system that's easy to clean and made with sustainability in mind. If you could help me understand what people are looking for in a tower, it would go a long way to helping me make a great design. Here is a pic of a tower I printed last summer, credit @SrDitamus. The survey is quick, only 6 questions. Any help would be amazing! Thanks for reading, and happy growing!

Help with vertical tower

Help with vertical aeroponic/hydroponic

I’m looking for some guidance with my concept for a vertical tower. I really appreciate any advice, especially from people who have tried it at home.

I have seen people make vertical towers from either 6” PVC pipe or 5”x5” PVC fence post covers. With the pipe, I have seen people cut anywhere from a 2” to 3” slit and melt the pipe. While the plastic is soft, they insert either a glass bottle or 2” or 3” pvc pipe (cut at a 45 degree angle) to make the opening. With the fence post, it seems that people make a template, cut out a bit of a semicircle shape, and insert a short piece of 2” or 3” piece of PVC pipe for the net pot.

  1. has anyone tried the above two methods? How well does it work? It seems like I’ve seen more people use the 6” PVC pipe. I have priced it out and it a bit cheaper to use 6” pipe, and if it really works, that seems a bit easier to me so I don’t have to cut a bunch of odd-shaped holes as I would with the fence post cover.

  2. how big of a net pot should I use? I’ve seen people use 2” or 3” without really an explanation as to why they chose that size. I plan of putting in some strawberries and lettuce and basil at first. For the next crop, I might add some tomatoes.

  3. some net pots use a sponge-like material and I have also seen people use a clay pebbles. Finally, I’ve also seen people use a bit of fabric to act as a wick. I plan on starting with seedlings, not seeds.

  4. I need to make the tower a bit mobile to move around in my garage as needed. My plan is to cut a 24” circle out of plywood and secure it to a furniture dolly. I would then secure a five-gallon bucket in the middle of the circle with the PVC tower secured in the bucket. I would then mount the lights to 1”x1” pickets, secured to the plywood circle, that would hold the 4’ lights out from the tower. Does that seem to make sense?

  5. how far should the lights be from the plants? I’ve read 12” - 24” inches? Should I make the lights be able to move closer/farther from the tower as the plants grow?

  6. I’ve seen grow lights on Amazon described as “full spectrum” but only project what appears to be white light. I’ve seen other

light fixtures, more expensive, that actually have different colored lights. Do either work? What should I look for when making the purchase? Is it colors? Is it watts?

Thanks for all of the help!!

Week 9 of Flower ….

Hey guys. Quick question. This is my first hydro run. I’ve got 10 years of living soil experience under my belt so I’m not a noob but I’m a noob to hydro.

Heading into week 9 and my ph keeps dropping. I assume it’s because she’s drinking water but not taking nutrients. Is this common towards the end of the grow cycle? She’s got a mix of amber/cloudy/clear trichomes and pistils are turning red. The roots are very healthy and branches are getting HEAVY. It Just seems like more of a natural process than anything.

Starting Guide for noobs

Hey guys

I need (some) help getting started. I have bought a indoor hydro-tower with two full-spectrum grow lights. The lights are positioned at the side of the tower, pointing towards the plants.

  1. What kind of measurement systems do I need?
  2. How often do i need to change the water?
  3. Do I need to add nutrients
    1. If so, how often?
    2. Which kind of nutrients

I'd like to create a getting-started guide, for noobs in the future. So please post your research as a comment.

Cheers

Using an indoor hydroponic system outside

Hi! Total noob here. I bought an indoor hydro system for growing herbs and maybe some veggies. The system has a water pump and a dedicated lamp and is targeted for indoor usage. However, I want to place it in my terrace instead (no direct sunlight). I was wondering, how would it affect my plants? Will the dedicated lamp have any effect this way? This is the one I bought: https://a.co/d/4QkOegH

Thanks!

Peat moss plugs in tower garden?

Saw those pop up peat moss things at Home Depot. Is that safe to use in a tower garden or will it fall apart or get in the water?
