Can I grow cannabis under a shade cloth from seedling to flower?

So I live in south Los Angeles and it gets pretty hot during the spring and summer,
I feel like if I leave them in direct sunlight on intense days they get baked just sitting in the sun all day like for example I have a cucumber plant and every time in the afternoon when the sun is intense it droops like it needs water but soon as it gets some shade it comes back up
Why is tht? I see others not using no shading

so I had built a structure and placed a shade cloth over , which also helps with pest like preventing bud worms ..

the shade cloth I am using is 30% ..

I would like to leave them under a shade cloth the entire life of the plant , would this be okay? I’ll maybe leave one plant out in direct sun and see the difference in using shade and not using it ..

Here are some pics of the plants under shade I took the large plant out and transplanted the ones in 1 gallon pots into 3 gallon bags

I’ll keep the large one in direct sunlight all day, and leave the transplanted ones in the shade structure unless anyone suggests otherwise..

Also I’ve been using supplemental lighting to keep the plants from flowering but since on June 21st the daylight will be going down I can stop using the supplemental lighting and let them flower with just daylight ,

this should be okay and will stay in flower and not reveg since daylight will start decreasing on june 21st/summer solstice right?

I love the setup! It may hurt yields to some degree (im not sure) but I love the idea of keeping budworms and other pests out. I would plan on IPM still. Your covered area won't be able to hold ALL those plants once they flower and double in size but I'm sure you're aware. With a 30% block out of sun and an added barrier it sort of acts as a "greenhouse." effect. I think if they're getting FULL sun under the canopy most of the day it shouldn't be an issue as your progress into the season and flower. The suns rays are still 70% penetrating. I would be mindful how dense you keep things in the enclosed are and possibly supplement airflow if you find your shaded outdoor area too dense. Keep us posted on flower etc I'm curious to see your results.

yes you can grow under shade cloth. Cannabis does very well growing under shade cloth.

if your plants are outside and in veg state & you turn off the lights in June, they will continue in veg for another 6-8 weeks. If your plants are flowering in june and you are using lights, you've done something wrong. They should not be flowering in june with lights.

Yeah they get sunlight from sunrise till about 4-5 and the shade cloth is a big help with most bugs and specially the blazing sun which what I’m most worried bout having them just baking under the sun from sunrise til 4-5pm..

I get plenty of air blowing thru my area I’m sort of on a hill from what I heard from my pops if tht plays into the wind we get here..

But not what I need to know how I’ll go about transitioning them into flower without revegging

No

The fact that days are getting shorter is irrelevant to a plant re-vegging; they'll happily start re-vegging on June 22nd.

The duration of the night is the critical metric.

Yeah I know it’s the darkness tht tiggers flowering , but I’ll refer to it how it makes sense to me (if I have 12 hours daylight Thn I should have 12 hours of darkness,answer won’t change )

but anyways why would it reveg?

if I’m giving them 18hours of light and 6 darkness and let’s say we get 14hrs and 30 mins on the 21st and 5 min less the 22nd and keep decreasing from there on ..

And going from 18/16 to 14/10 would trigger flower since it’s getting less light and since the daylight is decreasing and nights increasing in the following days

Wouldn’t the plant sense tht it’s loosing daylight hours and increasing darkness hours
And remain in flower

buuut what I forgot which is what your saying I think is ..

On the 21st I turn off the lights and we have 14hrs30mins ,yes it would trigger flower but then reveg cause 14hours and up is still sufficient for vegging … right?

so if I want to avoid revegging I’ll keep the lights on till it gets down less Thn example>13 hours daylight or less , whatever number is low enough for flowering.

or

reduce light schedule on weekly basis untill it matches the natural day/night cycle

If I’m still wrong lol what would u suggest to transition into flower without revegging

No there not revegging right now I’m using supplemental lights to prevent tht now I’m trying to figure out how to transition into flower without revegging and preferably would like to flower without using lights or light deprevation, And they should continue to veg since the day/night cycle is still sufficient for vegging and untill they days get short/nights long enough to trigger flowering right?

If I understand you right I think one thing you are confused about is that since they aren't flowering yet, they cannot 'reveg', they can only 'continue vegging'. Other than that I defer all answers to these who know. Good luck though!

your plants should be in veg right now, they will continue to veg and grow until mid to late August and transition into flowering all on their own with natural light. The shade cloth will not effect this transition.

Shade cloth is awesome. I have tried it without it and with it in the desert Summer. Plants love it and still gets plenty of light. I forgot to do it this year and feel bad for my little plants. They were doing so awesome. Going to buy more tomorrow

There’s no reason to add supplemental lights if you’re growing full term . In the beginning sure but June is when the sun is at its longest. Your plant is either in veg or in flower . Your plant will not go into flower until about August 15th when sunlight decreases below 12 hours a day .

There’s no reason they would reveg unless in September you started supplementing lights. The plant will not flip into flower until sunlight is below 12 hours a day . Unless you do light deps , this is the natural cycle of the plant

No ,

the only thing that can trigger flower is less than 12 hours of daylight .

Going from 16/8- 14/10 does not tell the plant its in flower. Only 12/12 can do that . You are growing full term. Only in the beginning clone/ teen stages do you need to supplement light and only if you’re starting “early” like before may. The ideal life cycle is may-late October with the plant flowering in August when light hits below 13 hours . It takes a plant 8-12 weeks to flower depending on strain so anywhere from October to November harvest. If you start your plants in February or something they will be in veg with light supplement until June when they can naturally get more than 12 hours
