Guerrila grow-heat stress signs, please inform me, how bad are they?

[ozzy987]

Hi

So, I have 14 plants outside, guerilla grow.

Almost all of them showing signs of heat stress, as in the past 3 days, it went up to 34-36 celsius. Thankfully from tomorrow, the weather goes back to 27-31.

But 3 of them in my opinion looks really bad compared to others, other plant leaves are "just" clawing.

I attached pictures, please guys fire away with you thoughts.

Many many thanks

In reality there's not much you can do other than try your best to keep them hydrated . You'd be amazed at what outdoor plants can bounce back from .

Plant some white Dutch clover around ur plants and lay some soil ontop (1/2 inch) , this will give multi bonus of retaining ur water more, deterring weeds, promoting predators and if u chop and drop ur clover (cut the greens) = result will give the chopped clover into nitrogen fixation bacteria . Key is a lil bit of straw at start so u don’t kill ur seeds . You’ll be surprised how much some straw and clovers do, cheap and very effective


Gorilla growing wise I would also suggest the clover cause once it’s established it will remove the obvious if your growing in a feild/forest/swamp or w/e that ur plants aren’t just wild plants vs obvious human grown farming , having a pure green ring around ur plants vs bare

Step-by-Step Instructions


1. Prep the Surface

• Gently rake or scratch the top ½ inch of soil in your pots with your fingers or a fork.
• Remove any dense mulch or debris temporarily.

2. Sprinkle Seeds

• Broadcast clover seeds evenly over the soil surface.
• For a 5-gallon pot: use around ½ teaspoon of clover seed.
• Try not to over-seed—it’ll crowd itself and your cannabis roots.

3. Lightly Cover

• Gently press seeds into the topsoil with your palm.
• Optionally, sprinkle a thin layer (1/8”) of fine soil, compost, or vermiculite to help with seed-to-soil contact—but don’t bury them deep.

4. Water Gently

• Mist or lightly water the top until moist—avoid heavy watering or runoff.
• Keep the surface consistently moist until germination (usually 3–7 days).

5. Maintain Moisture

• Once sprouted, reduce watering frequency slightly but keep it regular.
• A light straw or leaf mulch can help retain moisture without smothering sprouts.

Care Tips



Do:

• Let clover fill in naturally—it’ll stay low-growing.
• Trim if it starts climbing stems or shading soil too heavily.
• Water normally; clover can take light foot traffic and light drought once established.

Avoid:

• Planting too early (young cannabis seedlings can get crowded).
• Letting clover flower excessively—cut it back to maintain energy in roots and nitrogen fixation.
• Overfeeding nitrogen-rich fertilizers—clover already fixes nitrogen naturally!

Benefits You’ll Notice

• Nitrogen fixation (feeds your cannabis subtly)
• Cooling root zone
• Increased microbial life
• Better water retention and erosion control
• Looks lush and helps outcompete weeds/algae

Put hay or straw or grass around the base of the plant, several inches deep. Will help keep the root zone cooler, the part above ground will be fine.

It gets hotter than that where I live much of the summer! Mulch is the key!

Not looking critical
Buy a shade cover of 30-40% shade
Put on top of them when its hot, remove in nicer temps
Problem solved
Plants dont care too much about ambient temps being high, its the direct exposure that slowly cooking them, the shade cover fix this.

I would think a shade cloth might draw undue attention to his grow. If the base of the plant is shaded he is good to go.
