I planted a couple of random cannabis seeds a few weeks back, they've sprouted and at the moment they have a 3/4 inch stalk and 4 small leaves at the top. How do I know if they're female? Also, at what point should I change them to their own individual pots?

Any websites that could give me some detailed info on making these bad boys big and strong?

Cheers.

It's going to be a long time before you can tell their sex unless they're put into flowering phase immediately.

Give them 12 hours of darkness and 12 hours light for a month or so, when they show their sex, put them back into vegetative. I'm assuming you must do this indoors, so I also assume you can change the light cycle when you want. If you're in the northern hemisphere then I think you should be able to just put them outside to induce flowering cause it's already october.

Even sativas should be starting to flower at this time. But I could be completely wrong, you should wait for someone that knows more about this stuff since my information is very limited.


Websites that may help are growery.org, rollitup.org , grasscity.com , cannabisculture.com


Put them in their own pots once you know their sex. For making them big and strong, you could try this stuff, it worked for pumpkins:

maple leaf compost.

RTI mycorrhizae www.reforest.com/

Seaweed

Fish shit

cow shit

and...... Some other suggestions, sludge from the bottom of a pond or clean river or swamp, as much different healthy aquatic sludges as you can find.

Mushroom compost

Rock phosphate

Green sand

Worm poop, fresh.

You can get the correct ratios for this kind of stuff on google or one of those sites. If I were you and I was gonna use this stuff, I'd just mix it in a ratio where it still looks like normal earth when it's dried up, no cracks or shrinking, using normal sand as the main ingredient, cannabis likes loam.

googling "cannabis growing" would yield you the answer.
