sirtom68: I have some videos here of my aeroponic outdoor system. The best way I
found to combat heat and bacteria is about 5 to 6, maybe 7 drops of
household bleach per gallon of nutrient water. It has worked for me very
well and I haven't grown an extra arm out of my neck or anythang. If you
can keep your reservoir covered and add a white external covering about a
foot around and over it you can reflect a lot of the suns heat away from ya
nutrient, which in turn will keep ya roots cooler. Like many have said,
keep the sun off your plants roots. Vent cool air from the vents under your
house crawlspace to blow into the reservoir if you can and don't run the
system in cycles outdoors in the heat, keep it running. Heat is the bane of
oxygenated water. Add an airstone if you can, overkill it. More Oxygen is
better. Keep ya pH in check, 5.8 to 6. Hope ya haven't given up. ;)
sandertel: First of: If you use a larger container for the main water supply you get
more thermal mass and thus less hectic temperature swings..
Secondly I recommend you bury the main water supply container. Let's say
you use one of these blue barrels. They come in various sizes (have the
largest one that you can), they usually have a practical (screw down) lid
to them and they are already opaque in nature. I recommend you plumb all
the lines which need to go in or out of the main water container from the
sides, thus leaving the lid free to open at will without having to deal
with the various tubes and pipes and such...
Also device a type of covering/shading for the exposed bit of the main
water container. I like the 275 gallon IBC totes a lot but they are large
and in your case an IBC would definitely be a thing set in place with
growth in mind...
Thirdly: Try and cover the buckets which the plants sit in, this will keep
radiant heat of the buckets and helps in keeping things cool. Maybe use a
second bucket to nest the actual planter bucket into to provide shade to
the inner bucket. Don't use any insulation if you may be tempted to try
that. Insulation may become water logged with all the negative
(pests/bugs/rotting/smelling) effects that may have...
Fourthly: I recommend you look into the use of fish (of any persuasion)
instead of the hydroponic chemical fertilization thing... You could grow
Tilapia or any warm water species and harvest the fish as well every now
and again. You just have to feed the fish and supplement some micro
nutrients every week or two.
You should be able to find a micro nutrient mix and ome seperate chelated
iron powder to help the plants grow well. The fish feed and fish waste will
provide you with the main nutrients: the famous N P and K elements.
Good luck, Sander Tel.
Th Linn gill: Alright young blood I have an idea for you. Go back to the bakery was it (
I get 5 gal. buckets for free at Dunkin Donuts and they come filled with
used coffie grounds which are great for your soil garden "Perfect PH") Get
new lids and this time when you cut the holes for your net pots cut hem so
the net posts go only deep enough to let the pots sit in to were the top
slot in the pot has part of the opening in the side of the net pot
still above and out of the lid so air can move in to your roots through
these slots This is a variation on Kratky's suspended raft method but with
your bucket lids. Or add air holes to the lids you have now to let in more
Variable Wavelength: Bury your reservoir in the grounds and use pipe insulation on your
deliver/return pipes and you should be golden. If your buckets get too warm
the increase water frequency.
Th Linn gill: Also, do you have a crawl space under your house? If so use this area to
barry some 4"air tubes that you can then run to your buckets to cool them.
Be sure to cover the inlet end of these cool air tubes with bug skreen to
keep critters out. This is an ol Indian idea we use out here in N.M. where
we have high temps also. If you deside to try this idea you can super
charge these air pipes by adding less than half thier volum with cold water
and they will act as a Swamp cooler type system. ( be sure to use masqitoe
egg killer to the water in the coller tubes so you dont get bugs.)
jffrywad: its your white buckets they conduct too much heat you need to cover them
with some black material then you'll have better results. or use black
buckets. Gl Thanks for the video.
henry wade: I use one of those reflective emergency blankets and wrap my tots. I am in
ms and mine stay around 80 degrees even when it hits 95
James Brown: Hello use a 55 gal food grade for your water reservoir to keep it cool put
it in the ground or use a dehumidifier for a D I Y water chiller works
good in FL
Ellenn Oits: if u cant bury your water bucket paint it white to reflect most sun
James, Moore: You might consider investing in a water chiller. They are pretty pricey but
it's a one time investment and it would rock your system. That or bury your
reservoir and insulate your pipes.
joe m: drop the tub in the gound it cooler there and cover it up
MICHELLE TOPLIFF: BLACK ASBORBS HEAT MORE
billrock12: Bring your setup in the house and that will stop a lot of problems like too
much heat, bugs that eat the plants, acid rains ect.. Home Depot sells a
150watt grow light for $90 and it's more then enough lighting for your
dav1099: Very nice video, try wrapping the buckets with tin foil, it will make the
inside dark and also reflect the heat of sun. I have had trouble in the
past with to much heat, when the back wall reflects hot afternoon sun and
basically cooked the plants, helped a lot when moved out from wall and got
air circulation. good luck thanks for posting. 8-)
mj leandro: Wow like this idea. Thanks for posting it.
parteofive a: what bout your wall are the plants too close , walls keep preety hot in
summer high temps?
Jay Michalak: Hey man... Just a thought might help you out... Try using a big cooler for
your Rez man that may help keep it cool
Blury Bury: great video nice build. brown roots = possibly bacteria according to the
garden pool guy. water crashing making bubbles is GOOD. nothing wrong with
that :) love the tip on the free buckets from bakeries! i will try that.
your water reservoir being black is good as far as antibacterial however it
needs to be covered,. the thing about Hydroponics & Aeroponics is it is
less bacteria since you dont have the soil involved as with conventional
growing. however without your reservoir being covered you have dust being
introduced into the system which can carry bacteria and worse if you have a
bird wishing to bath in it XP. flush all the water out and empty the
reservoir and clean it out. even sitting it in direct sunlight for 30
minutes will kill most of the bacteria once it is dry. id clean with 1 to
10 parts bleach water. then let it dry out in the sun to let the chlorine
will evaporate as well. do this in 30 minutes time and you should have no
ill effect on the plants. run your pumps on a timer 30 mins on 30 mins off
and yes your pump is pretty strong so just add some more dutch buckets
perhaps. dont forget to clean the pump too and you can use a black light in
the dark to tell if there is any bacteria as it will be fluorescent. for
cooling id suggest if not to bury the reservoir then to use a tarp as a fly
but burying is probably best and you could keep the pvc pipes cooler by
using a pool water weenies from dollar tree for a buck each. them pool
water weenies just slice it down one side and slip over the pipes or just
use the pipe insulation from local hardware store. but i found the water
weenies to be thicker and cooler but not always practical though depending
on the setup. alternatively you could use a fly over them as well though.
Judelia Medard: Tremendous!! I want to get into this for the new year. Building the
reservoir looks intimidating. But I think that Hydroponics is worth the
Rob Boone: Where are u located? I'm in Titusville on the east coast and am looking for
fellow gardeners to exchange ideas in our environment.
Jbasshead ice: Your Reservoir is black which heats the nutrient solution bro, swap it with
a white one, larger if u can also, white will keep your solution cooler
than the black container, also ur drip lines need to be insulated cause
they are black too :)
Tommy Graves: start over and go online to checkout the 4 inch pvc pipe hydro system with
circulating water . Your plants here are growing longer because of lack of
sun and use a 20-20-20 nutrient.
Gene Torres: you may also want to add a shade cloth, I'm in south Florida and had
similar situations and found that a 40% shade cloth works wonders in
keeping your system cool and promotes better growth for veggies.
joseph zimbler: TOO CLOSE TO A WALL, NOT ENOUGH SUN LIGHT, HOW DO YOU PLAN ON GROWING
ANYTHING?and you cant move it now......
Daniel Littman: Thats cool bro.
xbloodz1: and yes u should do Black buckets next time or put some black paint on them
xbloodz1: Check ur PH man i am sure that it well help if u have it at 5.8-6.0
Jo C: Understandably this is an old video but the knowledge may help either way.
There are basically 2 options when growing in a hot environment. Cool down
your reservoir somehow to around 65-75F OR use hydrogen peroxide to keep
the root issues away. Using h202 is a last option as you will get reduced
yields compared to doing it "right" but you will get "yields" all the same.
The reduction will be something like 10-20% of what you'd get in a system
where the temps were done right and beneficials and enzymes are used. You
of course cannot use enzymes and beneficials with h202 as it'll kill them.
If you use h202 and you go with that method you cannot stop using h202 or
it's like instant root rot and an onslaught of issues from the heat. h202
will help to add back some of the oxygen you are lacking because of the
heat. Dissolved oxygen is the key problem with hot res temps and this
solution will work and correct your res issue however it won't help with
plant stress so don't add too much. Something like 2ml-3ml per gallon of
h202 every 3 days should be perfect.
Chris Elliott: if you cant sink your reservoir, raise it off the concrete. Concrete will
absorb heat (from the sun), and will transfer to your reservoir....maybe as
simple as placing a couple pieces of 2x4 underneath it.....
randall lloyd: The reason your water is warmer going in is due to the black reservoir
absorbs the heat & the white reflects the heat. Put a few pieces of wood
under the reservoir to get it off the hot cement and either put some
styrofoam around the reservoir or some bricks around the outside.
wckdkl0wn: Just my 2 cents. Take it as you will. System looks great. But what I would
do is find a different water container that is lighter in color. Maybe even
something larger. Also cover it some how. Tarp or something to help keep
the sun off it. This may help with your water temp problem.
Henry Fairbairn: definitely bury your resevoir
Stephen Edwards: keep the water cooler by digging a hole to put it into the ground
temperature will help
KevinRayKnight: Sink your res. into the ground. It will stay much cooler.
jim kimball: good video how often do you have to change the water
John Cozad: the problem is your nutrient temp . you need to use a cooler outside and
freeze 2 liter of water and throw them in there . temp should never go
above 73 %
lunker012: I too am from Central Florida. Just started doing hydro for vegetables but
have some observations to possibly help. You need to use dark buckets to
reduce the light in the bucket so painting them black would help. Over the
black paint you should then paint them white to help shed the heat. I would
also do the same to your reservoir. I would also dig a hole and submerge
the reservoir approximately 3/4 into the ground and insulate the exterior
of the reservoir. I also have a sheet of thin foam insulation that I place
over the top the the reservoir lid to keep the sun off the reservoir. I do
aerate the water with a large air stone.
I too use the pump to empty my reservoir by installing a hose bib above the
pump PVC line above the reservoir with a shut off above that and use a
short piece of garden hose to drain the water or get water samples to test
the PH or TDS or to recirculate the reservoir when making PH or TDS
adjustments then open the shut off valve and close the hose bib to sent
nutrient water to the plants again.
You system looks good. Congrats to you on the new baby!
Sean Kelley: looks good but the water gets warm and they don't like it gets the roots
which it gives the plants stress
saborguerito: Use a black buckets for light problems in the buckets and a lid on the
reservoir to keep out light
Mr T: bad ass!
John Cozad: also put a lid on it . light creates problems with nutrient
psilverman9300: you can also use a radiator or chiller to cool the res
blackbeardSCBC: Actual walkthrough start after life story at 3:00
Antoine Kerfzhan: bury your bucket in the ground and cover with insulation panel from a
John Cozad: I am from orlando , live in n/w fl now
Hydro Redux: I'm glad you liked the video and thanks for the tip of the wooden box I
currently wrap the tote in foam panels but may have to try out the wooden
box to create more insulation also to keep it off the concrete slab as it
also radiates heat. I've been debating on adding a timer but don't know if
it will benefit the plants since there isn't any media in those buckets.
They are constantly being fed by the drip lines what would be the benefits
of adding a timer?
Frank guillen: hi mate, you roots are brown because the is too much light in the bucket
light water & nutrients produce algae is recommended to keep as dark as
possible .heat cause lack of oxygen in the water you can use an air pump
that well help regards from down under
toonces2011: Nice set up, looks like mine. I too am a fan of MHP and Urban sunshine. You
could try to build a wooden box around your fill system that's what I did
to help keep the water cooler, I do put ice bottles in it. That was a great
tip on the grocery stores for buckets, I bought mine at Lowe's and built
them fairly cheap.I have mine on a outdoor timer Lowe's $15 and it feeds 10
times a day and I think that helps with the heat also. Great to see other
central fl people doing the buckets.
John Cozad: I have extensive experience with hydro .
mj leandro: Wow like this idea. Thanks for posting it.
