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.
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.
Ellenn Oits: if u cant bury your water bucket paint it white to reflect most sun
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
mj leandro: Wow like this idea. Thanks for posting it.
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
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.
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
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.
Stephen Edwards: keep the water cooler by digging a hole to put it into the ground
temperature will help
joseph zimbler: TOO CLOSE TO A WALL, NOT ENOUGH SUN LIGHT, HOW DO YOU PLAN ON GROWING
ANYTHING?and you cant move it now......
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.
Henry Fairbairn: definitely bury your resevoir
xbloodz1: Check ur PH man i am sure that it well help if u have it at 5.8-6.0
KevinRayKnight: Sink your res. into the ground. It will stay much cooler.
xbloodz1: and yes u should do Black buckets next time or put some black paint on them
John Cozad: I have extensive experience with hydro .
Sean Kelley: looks good but the water gets warm and they don't like it gets the roots
which it gives the plants stress
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!
saborguerito: Use a black buckets for light problems in the buckets and a lid on the
reservoir to keep out light
John Cozad: I am from orlando , live in n/w fl now
John Cozad: also put a lid on it . light creates problems with nutrient
Tony Martalk: put it in the shade bro... your pool
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 %
Tony Martalk: hope your weed plants look better! :) nice setup, heat management got to
be hard to deal with!
mj leandro: Wow like this idea. Thanks for posting it.
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.
Holiday: We don\t make alot, but our group do get to travel frequently. Just this year we went to Bangkok to get pictures and their holiday schedules. We are still in a growing phrase so best we can aim for is break even. I think everyone have to overcome the same type of challenge when starting something new. Don\t give up!
