35 days old, light? + humidity

[superBOB]

When to go from 18/6 light to 12/12 hours?
My plants looks fine and are 35 days old. (about 40 cm tall)
The soil is a mix of potting with perlite and leca-stones in 10L buckets

Humidity:
I grow in a growtent 80x80x160 and i run with a 400w cooltube.
The temp is 22 degrees and humidity 40%. (how can i raise it?)
There is a fan blowing underneath the branches of the ladies.


Thanks for your time,
Enjoy your

regards
BOB

whenever you feel the time is right...basically when your happy with the veg.

You can force flowering at any point during veg. Size of the plant when you force dictate yield. As a personal preference, I switch the light cycle when the plants have reached sexual maturity. i.e. females produce pre flowers.

How tall can i expect the plant to grow after switching to 12/12?

They are 35 days now, so if i do it at 45 days, they will be ready to harvest at 70?

1.it all depends on what your genetics are.

2.youll need at least 8 weeks of flowering.

3.my jedi senses are telling me that you need to read more about growing pot.

No, they will be ready 63 days maybe a little longer maybe shorter dependent on strain from the day you flip to 12/12. PEACE!

Im growing Barneys farm LSD, kiwiseeds - Mako Haze and Milky way.

2. Do you mean, that it will take 8 weeks, if i switch to 12/12 now? At what height would it be recommandable for me to turn on the flowering period as i have about 60cm from top plant(now) to highest position of lamp in my growtent?

 

[Guest02345]

yes it will take 8+ weeks from the second you flip your lights to 12/12.

im not sure about cm. but a safe guess would be they will stretch 2x-ish

Oh geez, guess i misunderstood the 12/12 thing completely. Will have to switch to 12/12 tomorrow. Whats up with the 24 hour darkness before going to 12/12.. is the wait worth it?

I would suggest you jump in the beginners forum and read. Evidently you have not fully understood photo periods as well as stretch some of the first things you will read about. You will never be successful in growing if you are dependent on others to do the work for you. You have to take time and swell ya brain a lil bit by reading and taking notes. Your questions you asked can be found just by reading. PEACE!
