Sythetic Nute Fertigation Reservoir Can be too Warm for for Soil-less Grow or Non-Issue?

Hi I am thinking to keep a synthetic-nute fertigation reservoir of like 15-30 gallons for a soil-less mix (peat/vermiculite) grow.

To be fed by a smart-home irrigation valve timer.

The issue, is that the reservoir will be outside in a hot environment.

I know this can be a problem for hydro (when the water tank-reservoir is too warm).

However I suppose that for soil-less, this might be less of an issue or even a non-issue since the medium acts as a great buffer?

I would plan to not change or refill the reservoir for about 2-3 weeks or so. To help automate the grow.

The outdoor environment is very tropical-hot and the fertigation tank could reach temps of 85 degrees even 95 degrees! I will plan to aerate it.

Please let me know your thoughts? Thanks in advance

its way too much for you reservoir, aerating with pump will heat it even more

if you really need to put it outdoor, you need to dig a hole and put the reservoir inside

If you can share the reasoning for this, it would be great: What is the issue here? It will not hold enough oxygen? It will build up negative bacteria? Or the warm water will harm the roots / not be able to feed the roots?

After all, I was hoping that the soil-less medium would fully buffer these issues. I suppose one solution would be to use a chiller on the reservoir if needed, however I would reeeally much prefer to avoid that hassle/cost/space usage.

I don't see a problem to this as long as you have a light blocking container. The media will quickly buffer the tempature and ph of the irrigation liquid.

your solution will hold less oxygen, and anaerobic bacterias will grow

what do you plan to water with this solution ? a greenhouse under sunlight?
is the room cooled ?

Yes I was planning to use a light-blocking reservoir container. Surely less oxygen will be held in the water but I dont see it as important for soil-less. The medium will have oxygen for the roots easily.

Aerating should take care of the bad bacteria, I was thinking. Even if some bad bacteria comes, I dont see how that could hurt the soil-less medium since it will not be hydro.

The room is sealed, running co2 (so I keep it at about 85F, not a greenhouse) in a 4x4 with aircon.

I think the root zone will maintain a fine, healthy temp most of the time. More or less.

As this is not an organic operation, I can also add a measured amount of some H202 (hydrogen peroxide) into the fertigation reservoir to cut down on any bad bacteria (while adding beneficial O2 from the H202).

Thoughts?
