The forecast calls for at least 2 weeks of temps in excess of 100. Along with this high heat, we will experience low RH--oftentimes in the single digits. This low humidity is as worrisome as the heat.

So, what are some of the things that others do to protect their plants in times of high temps and low humidity?

I find that mine do not grow in triple digits and they will not use that much water. You can cover with a tarp during the hottest temps. I have been known to mist my plants when it is hot and they seem to appreciate that. They are surprisingly hardy in this heat.

Rosebud, I was wondering about misting them. Do you just go out and spray them with a fine mist of water? I was wondering about something like the misting systems they use on decks and patios for people? I was thinking they would need more water with the heat and the RH being as low as it is. Maybe I should invest in a moisture meter? Not like you can lift the pots to see if they feel light. The hottest part of the day is around 6 in these parts. I have a nice tree that starts providing shade around that time of day.

LOL--mojoganjaman, I'm thinking that you have a much better outdoor growing environment than I do--I don't even consider 30C (86F) hot yet. It is pretty much that hot most every day in the summer here, with most days being hotter. I think the average daytime temps in July are 92. This 2 weeks of 100+ will put us over that this year though. I water every morning. I was actually wondering about watering twice a day.

Thanks

I also cover the roots with hay or straw, but be warned if you used a lot of myco's you will grow a huge fluff of mycos under your hay that you may be worried is mold. it isn't it is all the beneficials , just move it to let more air in. I just go out when it is scary hot and put my hose on mist and stand there like an idiot and mist them, then i go in the house and die of heat. Isn't growing fun. Oh and i still judge the moisture in the soil with my finger... You will be surprised, i was, at how they are still moist under there.

I had always thought it was good to water in the morning so they faced the heat of the day well hydrated, but hear you about evaporation. The hottest time of day is usually around 6 in the evening here. I go out sometime in the evening before dark to make sure they don't look thirsty when it is really hot. Also like to check on the chickens in weather like this. Today was 103--105 tomorrow.

Where I live it gets triple digits only a few times a year on a good year on a bad year we May have a few week's of 99-104 degree weather during this time I as rosebud said will mist the plant down with the hose on mist or shower mode after sunset never mist plants while the sun is out and water at night and use more water then you usually use I double to triple the amount and during the few weeks in a bad year of high heat I water every night the misting and water after sunset helps the plants take the heat and stay hydrated threw the hot weather

thg, you are getting lots of ideas. Here are a few of mine. Last night at 8 pm with 103 degrees with a slight wind my plants looked sad. I would not water at night or mist because of fungus, i know sounds impossible in this low humidity, but it isn't. I knew they had been deeply watered yesterday morning so i didn't water. As the low is 68 this morning they have perked up. I will watch them today and stick my finger deep in the soil. My hose as a misting thing, i also have a misting fan, that helps up the humidity in the garden during the day and I don't have proof, but i think they like the moisture in the day. not at night. It is a real trick to grow in this July heat. But it can be done. you go girl. you got this.

Rosebud, our climate is so alike. I really depend on your knowledge and experience. Fortunately, my plants seem to be holding up pretty well so far. I have soaker hose run to each pot that comes on automatically at 7 in the morning. I did go out last night just before dark and gave them a drink and misted them though--never even thought of fungus. I'll be more careful. I've got a misting thing on my hose too (I copy you a lot). I think when the humidity gets as low as ours does that they probably need the moisture during the day.

I watched the video link you posted about spreading the plants out. I had had something like that in my mind for my plants but hadn't quite worked out the details, like how to work on the bottom of the plant if it is caged. I, too will be off to Home Depot today. Picking up some plumbing parts to install a bigger pressure tank and some wood and hog panels to put a new railing on the deck. Looks like I'll be picking up some gardening supplies, too.

Very cool THG, I really like that video series. I haven't watched all of them, but he likes to harvest in layers. Take the lowers later, which may be not possible in our neck of the woods because by the middle of october we have to have them all down. Maybe indica's would work that way. Yes it is amazing how they stand up to this heat. They do way better than me. Hardy plants this cannabis.

Not totally on topic but a singer in my band had his brother with him last night, visiting from Oregon. He said he lived 'right on the central coast', whatever that is. LOL

He was a very bright guy. We talked quite a bit. He is retire military and has been in OR for about 6 years. It's funny, he is involved in the pot business there but he doesn't smoke it. LOL

He did mention something about the OR law changing after political name/Sessions came in.

From what he said, OR pot laws required a photo ID to purchase and records of the sale were maintained. After political name/Sessions, the law was revised to dispose of all previous records and not to require photo ID to purchase. Pretty cool, if that's true. Good thinking, OR.

Hackerman, I am on the other side of the state--the desert eastern side. By central coast he most likely means that he is in the center part of the state on the coast, probably somewhere around Newport.

I love Oregon...just so progressive!
