when is the next stage

Can anybody please help!! (First grow) My greenhouse- growing plants are 6 weeks old (from seedling) and approx. 17inches tall. I have staked them up as they were toppling over and they are still looking healthy. When do they go on to the next stage? I will have to put them into a bedroom with blackout curtains, what is the normal period of complete darkness they need daily and will this help them to eventually flower? thanx

yup you can force them to flower by putting them in a dark room for 12 hours a day. make sure they get moved at the same time everyday.

Why are they flopping over?

The longer the veg period the bigger your plant will be. Don't overdo it or you'll have a tree to move around every day. They are able to flower after a few weeks so you are more than ready. Make sure they are in complete darkness for 12 hours every day and that your time is consistent. They should display their sex within a week and you can go from there. Good luck & have fun - this is the best hobby ever!

Well, they sound to be mature enough to flower. Have you sexed them? Make sure they have pre-flowered before forcing them to flower.

OK great, I will start to do that from this evening, thanx

I think its because they are growing upwards and not bushing out yet, is this normal?

Will start the 12/12 system tonight, thanx

yep it's maybe the strain(sativa), you can top them if you like and lst them or both.Read some thread about topping and lst and come back with fresh questions,good luck!

Not quite sure how to sex them, what is the difference between pre-flowering and normal flowering, how will I tell?

If you're plant is "toppling over, there is something wrong. I can't believe no one else said anything. Was it grown outside, inside, what kind of light? Did you have a fan blowing on it? If you had it inside with no fan/no good lighting....probably why your plant is falling over.

Do some research for yourself. Before I even started growing I was on this site for about a year reading and learning. I don't suggest you wait a year, but def. start reading up some. Pre-flowering is when your plant shows sex before your flowering photoperiod. Little white transparent hairs mean female. Little balls or sacks=male.

You should try and research as you go. If you try and absorb it all now, you may get confused. If you are about to start flower, study up on sexing, photoperiods, identifying hermies.
Once you got that going with your plant and things start moving along in flower, start reading and studying the next phase, examining trichomes, identifying nute deficiencies, looking for bugs. Then harvesting, drying. You have to study and always prepare yourself for the next cycle or phase in your garden.
Are you ready to flower? Have you determined the area you will use that is free of light? Have you decided what time of day you will run your 12/12 light cycle? Does it conflict with your daily schedule, like going to work?
I'm not being condescending, my point is... the more research you do, and time, love you invest, the better your end result will be.
Knowledge is king they say, and I want to be the boss of my castle.

As they say, a picture is worth a thousand words. It would be of great help to get in the habit of posting a pic along with your question/s. Pre-flowers are easy to identify. Look at the nodes around the forth to fifth branch internodes for small buds (calyx) with a couple white "hairs" protruding (female pistils). I suspect the toppling is the result of no external stresses (fan) which make the stems stronger. A lot of greenhouse plants do not require this stress, so it's an easy oversite to make and correct for.

got ta have a fan blowing on them for stem strength. shud of been from day one..keep in veg for bout 6 weeks in a 24 light cycle or go to 18/6. veg is with 6500k light then 2700k for flower. flower for bout 60-70 days and viola!!! cut and cure

all good advide, anyway we can get a pic? it will help us help you too GOOD LUCK!

They have been in a greenhouse since day 1 as a seedling, loads of natural light and correct temperatures with a good airflow.
