How big pots i need so that plant roots gets enough space till it reveals sex ?

I have around 30 sativa seedlings (one day old ) in a germinating tray and i am planning to transplant them at my backyard in pots.. as per my calculation plants will get 10 hrs of direct sun and 3hrs of indirect light.
My question is " How big pot i need so that it will be enough for the plants TILL IT REVEALS SEX (male or female?) "

My plan is when they will reveal their sex i will kill all males and retransplant only best 15 females from 1st pot(size?) to 5 gallon pots..

Bros, pls tell me how big pots are need ?

I start mine off in 1 gallon mineral water containers. Read my link below on sexing.

Do you think 1litre bottle will make enough space for roots till it shows sex.. (around 3 months) ?

if you want a root bound and stunted plant sure

realistically you need to be stepping up pot sizes as you go. 1l for 3 months couldn't support a daisy very well

Will 2 litres mineral water bottle can work so that roots don't get bouned till it shows sex?

Its indian sativa..
Any suggestions how much big pot should be used?

It isnt ideal, doesnt mean it won't work. You could use some nice width for rooting over a few months.

You would have to explain your seasonal changes and weather patterns etc to know what is best for outdoor plants

I am from India and its middle of spring now.. Winter season will start from november..
Pls suggest idle size..

Start the well rooted clones indoors in $.20 1.5 gallon growbags. When the plants hit about 20" tall transplant them to re-purposed food grade 5 gal buckets and transition them to outdoor gradually. I don't have any varieties that take 3 months to show sex.... so not sure whats up with that. When the plants hit about 4-6' outdoors you'll need bigger outdoor planter pots. I drill 1/4" holes all over the sides and bottom of the buckets and line them with cheap fiberglass screen material. I've also found it very beneficial to create drainage "zones" within the media. A 3" deep layer of coco on the bottom... a 2" deep layer of pearlite/vermiculite ontop of that.... THEN your soil mix....

Why the coco then perlite/vermiculite col.kif??

The coco acts like a moisture sponge and allows air into the bottom layer for root health. It also acts as a filter. The pearlite/vermiculite is a transitional layer preventing the soil above from admixing all the coco. It holds correct moisture/air ratios and allows the roots to breath. It's very difficult to overwater using properly layer strata.

Cool, thanks. I think ill try this next year.

If you are going to try new things next year also consider using Smart Pots. They are a super sturdy fabric pot. They allow for exchange and evaporation from all around the root zone. They also don't hold heat like a regular container.

what one is trying to achieve , irrespective of medium is good drainage!
