First Timer (color spectrum)

[jsaleen]

Thanks Rollitup community. Tons of very usefull info.

Any thoughts on running 24hrs of 2700k for flowering?

I have been using 6500k for veg from day one. About 6 weeks. Couple plants are showing some pistils so I did 24hr of no light. Now I have started 24hrs of 2700k for flowering only.

All 48" Flourescent

no no no


12/12 for flowering and yes 2700k are the right spectrum

12 hours on and 12 hours off for flowering....

16/18, and up to 24/0 works great for veg....i like 16/18 the plants and your lights need to chill

2700K Flowering is the right spectrum.
Wrong light cycle mate!
12 on 12 off!

yea fix it quick! or your plants will have a penis

i know 12/12 is the way you should go. This is a project so no big deal what happens. 12/12 unless you want a hermi yes. But what really causes a plant to become a hermaphrodite?

alot of factors can contribute to causing hermie's.

A hermie is a kind of safety mechanism to make sure the plants genetics can reproduce.

It can be caused by Stress, genetics, lighting, severe nuteburn or even genetics .

There have been growers experimenting with 48hour days rather than 24hour days.

They generally run lights for 36hours and then have a 12hour dark period.

Something you should look into if you are trying a few experiments with lighting etc.

Thanks, that makes a lot of sense. Do you think I will for sure end up with hermis if I do the 24hr lighting using only 2700k. I don't see them beeing stressed at all but as for the other factors I guess it depends on the strain.

Using flowering spectrum bulbs on 24hours a day they will probably stretch and not bud as there will be no dark cycle!

The dark cycle is what helps to stimulate flowering.

Without a dark cycle your plants would just continue to veg but it would probably be a little sporadic due to the wrong spectrum.
