Changing from 18/6 to 12/12.

Plexi1000started grow question 4 years ago

All previous grows were Auto's, so learning with my current photo plants.... Question on flipping to flower... I'm at 18/6 now. Do I just make the change in one swoop to 12/12, or is it better to progress there (taking 30:minutes of light out of each day until 12/12?).

Great advice all; That why I love this place - tons of experience and perspective. So my take is that I can do either, just jump to 12/12, or progress. Different perspectives but knowing that either is OK is what I needed. I'll probably split the difference (progress over like 3 days).. Thanks all.

Hey there mate ; i currently tried both techniques.. and found gradual decrease in light is far better.... the stretch is controled by gradula decrease in light and what you get is really dense top bud. Also the plant feels more natural this way. I also tried flipping directly to 12/12 and found that the plant stretches double its size. Well i like the gradual decrease in time and so does my plants. Hope this helps.. happy growing..

Once you decide you're going to flip them to flower just go directly to 12/12, no need for a gradual light change.

Indoor start and then move outdoor Complex question: I'm going to start my seedlings indoor and move them outdoor after almost one month of vegging. I live in the North of Spain where there will be 13 h and 1/4 when I'm planning to move outdoor. Are they going to stay in veg if I start them in a 13/11 cycle?

pH very low (5.0) but plants seem to appreciate it!!The pH of the reservoir is lower than the perfect range (5.0) during flowering stage for almost 2 weeks but plants don't seem to suffer. They are growing very fast. Should I change it or leave it if they seem good?

Lower lighting at switch to 12/12?Do you typically want to lower your lighting when you switch to 12/12? I'm a little confused about what is meant when they say to have a 12" light distance for flowering and 18" for veg. Does that mean lower to 12" at the switch to 12/12, or just maintain a min 12" distance?
