Question here about when to change to 12/12

[GelenaAK420]

When do you know it's time to change to 12/12 flowering ? Is there signs that one looks for in the plant or just wait till the desired height you wish to start at considering the space a person has to work with...??????? When looking at one of those feed chart schedules posted here in different threads, the manufacture shows that they're telling you to begin feeding for flowering after six weeks of veggie stage. I am sooooo confused...... Can someone shed light on this for me. I just want to know more before I might possibly attempt a grow. Thanks folks, much appreciated.

There's no set flower time. As you said, it's based on the space you have. Some people do 12/12 from seed, others veg for months.

Flowering can begin imediately with young seedlings or freshly rooted clones. It truly depends on the available space, circumstances and grow style.

Oh no. Major concept adjustment. It got me too at first.

Shed light? A pun. They need no veg and can use 8 months or even 2 years or more. I have kept Clone Mothers for a long time.

So, the point of all this is? It is too confusing to explain. And most people, including me are either too confused to explain or they are in some myth or commercial bs.

So. Basic concepts. OK?

- Learn how to fail and get used to it

- Experiment with what works for you

- Get roots in a plastic cup with almost no watering. I call it Root Hunt. That only takes a week from clones.

- control overwatering by using small containers and transplanting a few times to grow a root ball, more ROOT HUNT

- Measure the concentration of everything. I use a PPM meter, but drops per gal or ml per quart, just measure it and take notes

- Don't fall for nutes and loollypopping and other cannabis BS. Plant food is all you need. (I use Sea Grow) Pruning is all you do.

- Botany is what we practice. And the practice of Botany is what we study, not cannabis grower myths

- Know the important minerals to add. Calcium/Magnesium (usually bought together) and Silica, for strong stems is all I add, any more.

- Understand this plant, collect pictures of Cal/Mag deficiency from the web

- Know you only need CFL lights, but there are better lights, that are much more hot and there are expensive rip-offs everywhere

- Know that 12/12 light period is the only thing that makes it flower

- Long Veg time at 24 hours per day, means more yield, from a bigger plant

- Know that it can brought to flower direct from a seed, no Veg time.

- Know that we cannot grow this plant. The plant will try to grow regardless of the environ.

- Only we can control the environment to allow better growth

- Know that your system which is you operating your setup is completely UNIQUE.

It is only your Situation, your Location, and your Funds, that make any difference to you. Nothing we say, will trump that.

Helps, I hope?

She will get 2 - 3 times bigger after you start 12/12. Waiting too long can cause problems with plant outgrowing space or lighting.

Your feed schedule will change in flower. What nutrients / system are you using?

The 6 weeks is a generalization. Some veg less, some more.

Thank you very much Mr. Doer, that was what I wanted to read - straight to the point. I was worried I was going to get a bunch of crazy answers back (lol) .

Personally, I do not flip to 12/12 until I have staggering nodes (nodes opposite each other are not at the same spot on the main stalk) and the presence preflowers. I am not saying that the way others do it is wrong, this is just how I do it, and flowering seems to trigger faster after the 12/12 flip IMO.

You will see preflowers and staggered nodes in as little as 5 weeks in veg, strain dependent.

No, I haven't started a grow yet, just trying to absorb as much as I can before attempting one. Plus where I live (AK) it might be too difficult cause our temps are most of the times below zero. Thinking of building a small grow with a heater system... Could you recommend a nutrient that you prefer...??? thanks

Well, that is true...if we go from seeds. And then you have to worry about the male plants each time.

There will be plenty of crazy answers, even from me. But, Growing 101? It is all you.

Another stupid green pea question please.... So do you think when some growers start too soon into flowering stage could cause stress on the plant, or should one really wait to at least to the point that the plant shows its sex before switching to 12/12 ...?

I have never seen 2x height, maybe 1/3 extra height after 12/12. but 2x bigger? Sure, counting the width spread. And the big flower heads get heavy and tend to flop around.

No, theses are more hardy that humans. In fact, only clever humans can manage to screw it up. So, forget all the stress stuff.

You stress. They just grow.

It is all about yield, not stress and the theory of stress, distressing us. So, you want low yield and lot of hassle? 12/12 from seed.

Good monthly yield is an environment question only, and only the environment causes stress, your stress is their environment.

Any environment we set up by definition, is stressful, unless outside in good soil, weather, etc.

Just like any production, you work backwards against Situation, Location, and Funds.

How much do you want each year? Will you do that all in one growing season, using natural light?

Or like me, will you use two lighting and humidity areas and harvest each month, by moving the plants, or do you move the lights? High humidity aids Veg. Low humidity aids Bloom.

I forget to add humidity and temp control as a basic concept, and I may as well add odor control also.

And ta da!!!

Watts is yield.

I like the idea of waiting for the presence of the preflowers to start first. I would think that this allows the plant to be at it's mature point of growth before triggering or tricking it into flowering. I would think that by doing this, starting too early, might cause Hermes.

Exactly. The plant grows, you make the decisions.
