New Grower Black pots overheat roots?

[san]

Hello everyone:

This is the first time i grow outdoor, and its getting pretty hot here ( 34° celsius / 93° fahrenheit in the shade ).

So, black pots can overheat and kill roots?, or i should´t worry about it?.

Thanks!.

Hey great to meet you!! Yes you should be concerned about it. Ideally you would make something to shade your pots or dig them into a hole in the ground.

Not sure if white paper in direct sun is going to be enough with temps of 34C in the shade.

In Spain I've seen grows quite happy in those temps - large plastic containers (swap out perlite for vermiculite to give water retention but retain soil structure) - and then place those plastic pots inside larger clay pots which you can keep moist/cool by by having some clay pebbles or broken pot at the bottom of the clay pot and just keep it topped up with water at the bottom (above the plant base). The wicking and evaporation via the clay pot will help keep temps down a tad - not much for in shade temps but for when sun hits it works well.

Brilliant solution, and great tip on the vermiculite switch too.

thx - my post didn't quite make sense to me when i read it back so this is what it looks like (ish)

The plant(s) shouldn't at any point be reliant on the reservoir at the bottom of the clay pot (it's toxic juice) - in hot sun the clay will accumulate salts pretty quick as it evaporates so much water - Lime/Calcate being our Spanish problem, it gets pretty salty/toxic (well out of pH << but remember your plant shouldn't be there - this is the cooler) - so i just scrub down the clay pots with a bit of boiling water to dissolve residues and reuse as required.

I also tend to UP the pot size a bit in hotter climates cause its a water buffer - plus I think those girls love the sun more than LEDs

Totally made sense to me....and it makes even more sense with the illustration!! Incoming rep for the efforts!
