time to switch to 12-12?

[bobby2sox]

this is my first time and i cant figure out when to switch to 12-12... They have been in the soul 13 days. I am growing under a 1000w HPS light, on an 18-6 right now. please let me know if i can switch.

oops, soil*

To be honest it just depends on personal preference. If you have the room to keep growing, keep growing. They say that a plant doubles in size during flower. So if you want your final product to be double that, make the switch.

Did those come from clones?

Wait until you see preflowers.....usually around the 4th node.

has to be clone Dfunk, i've never seen something grown from seed that size.

They have been in the soil for 13 days. Where were they before. Ya know the other 4 weeks?

You can flower when you want..but to get more then g's let them get to 18-22"...
oz's are better..

 

[mrjaeyun]

how is that 13 days old. It looks like they are at least a month older

 

[gohydro]

I'm not sure I'd doubt the guy. I've grown some not quite as big....maybe 2/3ds the size and I was under (2) 400s. He is under (1) 1000. Then again...I grow hydro.

I've come to the conclusion that his plants are clones. Flower when YOU want to & remember they will double in size so if you started 12/12 now they would probably be around 3' tall when finished.

Listen to Dfunk. If they're clones you can flower anytime. If they are from beans I wouldn't go to 12/12 before preflowers show. In some cases they even triple in size too so consider your ceiling height/light fixture arrangement if you can't LST

Nice follow up gohydro!

 

[bobby2sox]

they were in rockwool cubes. I got them as clones, they were about 3" tall each. I will watch for preflowers (im guessing little hairs...). Thanks.

 

[bobby2sox]

I just saw that there is a second page of responses... they are from clones and I will wait a while before i go to 12/12 since they will only double. I have about 3 more feet i can take the light up and i have about 3 feet from the lights to the canopy. Since they are now about 12-15" tall i will wait till they are an average of 18" so i get a final height of 36" and still have 3' to keep the light away from the plants. Does that sound like a reasonable plan?

 

[Dfunk]

Two little hairs is correct. Your plan sounds great...keep us updated!
