The roots would stay much cooler if you dug them in. Maybe even up to 20+ degree's cooler...

What will hot roots do to the plant?

Man that is one offensive sig

Hot roots = stressed roots. Stressed roots = unhappy plant.

Just stick your plant into the ground itself.

I am glad u like.
Can u help with my problem???

Should I dig holes and fill with soil and use the pots like plugs. The soil here is sand. How big should the holes be?

Step 1: Dig a big ass hole
Step 2: Fill it full of potting soil
Step 3: Put your plant in it
Step 4: Take care of your plant
Step 5: Harvest
Step 6: ????????
Step7: Profit!

Gotcha.
What about 103F and 18RH?

The temperature should be fine, depending on your strain. Don't know what the hell 18RH is, though. >.>

Relitive Humidity

Oh. Yeah. Low humidity is good.

Well I am getting black leaf edges and have had 2 plants die.
Getting necrosis in some of the leaves, may be a ph def.

Yeah, get them into the ground with some nice potting soil. Water them regularly with subtle nutes. They'll bounce back.

Gotta run. Will catch up later.

Mist the plants with water that will help them stay cool

Well we will see. I have moved them into the shade and have perfected the ph intake so thats all I can do.
The plants are on a rock shelf so I got about 7" down and hit fukin rock. So burying them is out of the question. Maybe next year I'll build raised beds.
Thanks for the help.
