well i want to get them as big as possiable but some one told me that they grow only double in size in flowering so if i start flowering next week and the plants are only 13 inches then they will be 2'' 6' when they are ready. Is this right? And when do you have to start flowering? In a book i read it said 6 weeks of age, can you keep them in vegation stage for longer or will it hert the plants? And they are under cfls right now but next week they will be under a 250watt HPS and i feed them fox farms nutes and use super thrive every other watering. They are always keept in the best conditions (fans blowing on them , frsh air, and perfect temps).

They can as much as triple in size during flowering, but in general it will be closer to double in size than triple in size. Best of luck

heres a pics of one of them. It is the second tallest (13 inches), i have one about 2 inches bigger. Is this a good time to top them? If not when? And does anybody know of a good toping site or can anybody tell me / show me how to top a plant correctly?

Here's a good post for topping/cropping info:

i wouldnt top my plants unless i was worried about head room, i ussualy start to flower at about a foot and a little, and they get to be about 3+ feet, topping has very little positive effects.

i disagree w/ jackdawack on this statement . i used to get 3/4 -1oz. per. girl in dirt . when i top them i as much as triple my yield . how is that not a positive effect ?

I'd top around the 4th or 6th node. After that I'd low stress train the plant. This will give you 8-12 big main colas (2 tops for every node below where you top, but the more colas the smaller each will be or the longer you have to veg. 6 nodes produced this plant(nov 27th). 2nd pic is what it looked like the day it was topped (oct 13th)

Yes, I top at about the 4th through 6th node too and the ones in the pics above should have been topped long ago. Topping them now (assuming you're ready to begin flowering in the near future) will greatly reduce your bud harvest as the plant needs at least a month to recover from the removal. If done early in life they will double to triple in yield but if done late, shortly before harvest it will have the opposite effect. If those were in my garden I'd let them go as they are.
