Arthur Pletcher: Do these buckets require protection, such as a tarp, from rain entering through the opening and diluting the solution?
sciencerocs: Move them away from that cinder block wall. that traps and reflects heat. tx panhandle gets much hotter and I grow them in direct sun , they do fine.
Deborah Elliott: there is a small wall on the other side of your tomatoes, you can put the bucket out of the sun there and place another wood sheet to keep it in shade, which will reduce temperatures in the water. Keep the water bucket totally OUT of sunlight and you won't have this issue. If anything, Place a vented wood crate to hide the bucket and vent in back so that when sun hits it, its still in shade. Keeps it cool and better for plants.
tommothedog: Hi Hydro,
The water is probably leaving the drain pipe cooler than the it is going in for a few reasons; when the water is pumped up through the drip pipes its surface area relative to its size is greatly increased allowing it to lose some more heat, and it can cool as it drips into the buckets this is also true as it leaves through the drain pipes. Also when the buckets sit in the sun they reflect more of the heat imparted allowing the interior to be cooler similarly with the drain pipe.
paul evans: How crowded are the roots - thinking of trying 4" drainage pipe - any comment from your experience on root volume you are getting?
trethehunter: build a wood box about 2 inches bigger around your reservoir. then add sand in between the reservoir and the wood box. get the sand moist. that will insulate your water.
Bernadette Husch: Great to see that... I made it too. Using inplix handbooks :)
Chuck Adams: I would suggest you bury your water supply to maintain ground temperature which is much cooler than air temps.. Also, is that a metal stake on that last tomato plant? If so, that can be detrimental, if not deadly to you plant. Metal can rust and cause root damage.
pedro de alvarado: how often do you change watter
Mikkel Lorenz: Great system! Next lvl: Solar powered pump
Regina Leathers: It might help to fill soda bottles with water, freeze them and place the frozen bottle in the container. It will cool down the water without adding more liquid to the solution.
Victor delosAngeles Jr (Mr. Pimpmytattoo): bury the tote in the ground it will stay cool...
Mitchell Jordan: I am in southern Ca...much hotter here. I use a 60% shade cloth. It drops the temperature dramatically and saved my tomatoes.
torry nerheim: Someone in me family decided to plant tomatoes against a wall and the heat was just to much, light was fine the wall got to hot. If I decide to ever plant in the wall location again I'll flash the wall with white cell foam maybe then it might work.
Cosmic Carrie: Im in central florida too
Greg West: You should be aerating the solution tank. And keeping the solution cooler helps it dissolve more gas (air). Look up and understand "Henry's Law" If you are not going to aerate then cycle your pump longer and more often, that cool cool it and aerate it..
Richard Love: You may need a bigger tote, 1000 litre works well for me, very stable ph and temperature, cheers!
MrKlink951: on your dead leave's just cut them off the plant takes so much energy to repair the burnt leaves so its best to take them off so no energy is wasted
kevin walston: 1st thing the black retainer tub draws heat,id sudjest getting a white one with a top,preferably sunk in.2nd on the tops if you want to insulate it even more,put light colored pebbles on it.the pebbles absorb the heat before it gets to the lid.
Bachhanial Games (Lethaldose74): The reason the pump outlet is hotter than the return is due to the pressure difference. Where there is a pressure drop, heat is generated. Pressure drop = power loss/ flow rate Power loss is usually in the form of heat. reduce pressure drop and/or flow rate to reduce heat. Since you have a high flow pump you are generating excess heat.
