What is the best length of time to keep the plant in the vegging stage, does it go by size of plant or lenght of time on 18/6 before moving to 12/12. Reason i am asking is because i have 3 in soil at about 2ft high and 4 in hydro but they are only 7" tall at moment. they all share the same room and i dont want to change lighting and f**k up my hydro's. They were sprouted just over a week apart and the soiled ones have grown like lightening. The hydro has over the last few days got a spurt on after giving them some nutes and i was hoping that soon they would catch up and i could then change the lighting from 18/6 to 12/12 so they were at the same harvesting time. I dont know the sex of them yet i have read on here that you can sex some at about 3 ft at vegging stage and other reports that you cant sex then till they go 12/12 and go into flower. i am not that bothered about the sex yet i am just enjoying watching them grow day by day. Obviously if there are males in the brood i will seperate them as and when, but it is fun to just watch them develope at the moment.. Main question i need to know is how long can they stay 18/6 ?
No need to yell, I can hear you. Plants should be sexually mature before inducing flowering. This is indicated by alternating nodes which generally occurs at between 3--6 weeks of growth from seed. You can keep them in veg longer if you wish. A pot plant more than doubles in height during the first 3 weeks of flowering and most growers keep this in mind when determining when to switch to 12/12. The only SURE way to tell sex is during the 1st 2 weeks of 12/12. The males will grow "balls" (pollen sacs). Remove these IMMEDIENTLY. The ones that don't grow balls are females. You'll be able to see the buds forming during week 3 of 12/12. P.S. Keep using veg nutes for the first 3 weeks of 12/12...the plants need the N.
first sorry about font size, did not realise it was going to look that bold. And thank you for you advise it was most welcome, but i still have the unanswered question about the hydros i have in the room that are a week and a halfish behide the pots. Shall i wait until these reach full maturity before i go 12/12?
