When to start flowering???

It has been 1 month since my seeds germinated, the guys from Green House Seeds told me that i should start flowering after 10 days or so, if i want to have a final height of 60-70cm at harvest time. I guess they were talking about 10 days of veg period. So would be too early or too soon to start when my babes are around 20-25cm tall???? And do i really need a 3 gallon container to grow a plant that wont be taller then the height im aiming for?
Hoping for some help in these matter!!!
Thanks for your time!

Here are my babes, they are The Church strain from greenhouse seeds!

wow good job
pinch n flower em

If that's the cabinet they're going to flower in, and if you have weeded out the males (if there were any), then yes, it's a good time to flower now. They look very healthy, btw, good job! ;)

If you're aiming for 75cm tall plants, then you could maybe wait another week. 75cm plants can be pretty big and lush and take up a lot of space though. I had probs fitting three plants that size in a 48"wx20"d area, personally. Here's a pic of three plants which I vegged too long, and which then exploded during flowering. It's been a battle. Heh.

Great site to watch bro!
I think by the begining of next week ill turn the lights to 12/12. By what you saw, do you think i could get at least 1/4 of what you have going on over there???

Take it easy man!

Yield questions are hard to answer, because there are so many factors that affect it. Good genetics, temperature, nutrients, pot size, ventilation, light. The holy grail is 1 gram per watt of lighting. Be happy if you reach half of that, and whatever you did wrong, learn from that and improve for the next grow. You can't predict eventual yield from the pics of a couple of young plants. I wish you could!

Thanks anyway! ill try to keep uploading new pics when ever i can!

iv seen those pics before

when you're plants tell you there ready, meaning when the pre-flowers have shown.

When to start flowering depends upone the size of your cabinet and if your plants tell you that they are ready. Most plants will tell you they are ready by showing you there pre-flowers.
