first off hope everyone is having a hoppy day!
And just a few questions, first i found a few seeds one day in a bag i had a i finally decided to plant them , i had 5 and four of them are now growing , approx 3, 4, 6, 8 inches - I'm am growing them in a greenhouse in my backyard and just wondering approx how long to determine sex , better in the greenhouse or out side in the yard!And should i keep them all separated all the time or are they OK to be close now ? They are 3 weeks old.
It depends on you where you plant them man. In the greenhouse, you can alter it's growth much more efficiently. Outside, they will get better CO2 levels.
Many many more variables are there, but your humidity, wind, high-low temps, rain and rain conditions, etc, etc, etc. each have something that they change in the plants growth. Depending on where you are, the exact soil conditions in the spot you're thinking of growing, safety from the law seeing them, you could also grow indoors. Are you a legal grower? That matters a lot too when doing an outside grow. Are thieves possible or likely?
Can you set up an inside grow room? If so, that's the safest way I know of in terms of legal stuff.
As for sexing the plants, do you see the two branching's just below the tip? See how they are even? Straight across from one another? When the plant Quits doing that and the branching is staggered or what we call "Alternating Nodes", then you can sex the plant by either keeping it in total darkness for 12 hours each day or taking a clone from the plant and doing the dark hours with only the cutting. This will cause the cutting to flower in about 2 weeks. Either way, after the flowering starts in either method, you'll be able to tell if the flowers are male or female.
You can keep the plants as close as you need to as long as no light is blocked, or as little as possible. MJ loves full sunlight as long as adequate water is used and the plants don't over heat.
Tell us a bunch more about what you want to do, (but of course nothing personal), and there are a lot of real pros in this group that will get you on the right track.
Good Luck to you man!
