Right now my plants are about 5 weeks old, about 10 inches tall. I've already identified them as females, and I'm wondering when I should switch to 12/12, I'm currently using 18/6. The strain I'm using is Fm4-easy bud from seeds direct flowrering time is about 7-8 weeks. I have enough space for them to grow appx. 21 MORE inches. I hear that plants can double or triple in height during flowering, so maybe I should go to 12/12 soon?
I would wait a couple more weeks if not three, Let them get to about 12" tall or when the nodes aren't even anymore, when they start alternating that means that the plant is sexually mature. But 2 or 3 more weeks would be good, more yield anyways.
Well the problem is I only have 21 more inches of space left. If they get to 12" tall then they grow 2.5 or 3 times in height over flowering I'm in trouble. They are in 5 gallon buckets. I really only have 21 inches of space left. I just don't want to lose yield. Oh yea, I'm only using a 150watt hps but I'm either going to upgrade to a 400 watt or add some cfls.
If you have height restrictions then get them into flower now. Pot can easily double or triple it's size during flower. What you have there is a 50% indica 50% sativa mix and those can get pretty tall. You might not get the potential yield for the strain but if you run out of space you are fucked. Flower now.
Yea it sucks because I'm getting 2 differnt answers lol. Someone says you're fine, others say flower now. My theory is this. They've grown 10 inches in lets call it 5 weeks. If they continue to grow at that rate in the next 8 weeks of flowering that would add 16 inches in height. That leaves me with 5 inches of free space. In theory I could let them grow about another week and still be ok. What do you think?
If you see that there female then start 12/12 now because it will just start on its own sooner or later.
W.T.H. VTEC!!?? Why not tell him to tie down??? Maximize your plants potential within the confined space. 21 inches NO PROB! I agree that the plant will become more dense during flowering, and I also agree that due to being 50% sativa its typically a taller plant, but keep in mind that its sativa side means it will grow slower during flower as well. If he has only grown 10 inchs in 5 weeks durring veg, he will NOT out grow 21 inch's if he is LSTing now. QUOTE ME! The grow guide on the seeds is FAR more accurate than ANY of us could guess. Unless your a mico biologist and have samples of the current status youre not SURE. (lol I am a student at the University of Alaska Fairbanks, working on a double major. Wildlife Bio / Renewable Resorces Bio. I am working on a project with a Micro biologist who I am on the phone with as I am typing this and he agrees) believe it!
LOL sorry that last post sounded hostile. I have not burned all day. FOUND OUT TODAY I AM GOING TO BE A DAD FOR THE FIRST TIME THOUGH!!!! HURRAY!!!!
tadaa-Everyone has differnt methods of growing Herb. If i were in the situation your in i would LST them down to about 5inches and let them grow some more. The older and more mature your ladys are the better the harvest will be(as long as there in good health). If you dont want to spend or dont have the time to train them throw them in to flower now or in a week. Like i said everyone has there own methods its up to you to choose the method the best suits you and your situation.. ALSO Not sure about you distance from the light but a 150 can be put with in four inches of your tops just have a fan blowing across the bulb(unless its aircooled already than no need for a fan(except to strenghing the stems).. hope all this rambling helps...choke with ya later... WOODsMANTOKER- CONGRATS ON FATHER HOOD <ZZZZZZZZZZll~~ i REMEMBER finding out about my first Its a great feeling.. GOOD LUCK
