would like opinions on seedling light schedule

[ZZTops]

Thanks OldMac, that make since...

It's not as noticeable with the females but the males drink twice as much as the females so they like to stretch...

Also in my hydro set up I cycle every 3 hours around the clock, so say it's a waste but I find the plants really like it...

Hey there WashougalWonder,

I guess I need to work on a more tacfull way of saying, your're wrong. :wtf:

The only reason I did not go off on GTD with his responce to me, was the vaporizer was loaded and on and within easy reach. :thumbsup: It would be nice if he showed up here again, and admit he was wrong about root growth. An apology is optional.

Just the other day I was reading a thread on another board when someone corrected the same misstatement, and least 5 jerks stepped up to say they KNEW roots grow in the dark, but the only reference they could cite was "I read it on/in a post...somewhere". I wasn't looking to start anything with GTD but I did not want to see more bad info spread around.

First off, it is fairly presumptious of you to call me wrong when I have given you TWO references for plant growth at night, one directly from this site. Secondly, I took you to task on your original response to me as it had obvious patronizing overtones. It is naive on your part to ASSUME all patrons of this forum are uneducated pot smoking fools. I am all for open debate and considering others opinions on a wide variety of subjects. However, it appears your word is the gospel. I didn't realize taking one course from a community college several years ago makes you an expert in this field, my apologies. As for me being thankful for somebody not going off on me on an internet forum in a medium of anonymity, I find this quite humorous. I simply came here to share my experiences and knowledge with others that may benefit from it. There are plenty of other sites that come across as more welcoming, and I have no issues going there instead.

Nice info there oldmac. :thumbsup:
This makes me wonder if you could help control stretch during flower by limiting it's water at lights out?

Is this one of the reasons why in ebb&flow some don't flood during lights out, but do so right before lights out?

As for the scientific reason why plants DO grow at night, here you go:

[align=left]During the daytime, plants produce energy in the form of ATP and NADPH (light reactions)...during the night, these energy forms go to the dark reactions (Calvin Cycle) to fuel the production of organic molecules from CO2 collected during the day...some of these organic molecules will be stored (starch) and some will be used for plant structural growth (cellulose), and some for other organic molecules (lipids, proteins, etc).[/align]

I'm a noob grower, on only my 3rd grow, but because of the idea of 24/0=more growth. I started seeds on 24/0 and was unimpressed by their growth. After 3 weeks, I switched back to 18/6 and within two days noticed a lot of new growth that has continued since going back to 18/6. I might have accidentally timed the switch during or just before a natural growth spurt, idk, but I do know they are happily growing up into fine young ladies(I hope) now.

Here is more scientific data to back up plant growth at night (with references). Thanks for playing!

Biologists Identify Genes Controlling Rhythmic Plant Growth

While most people might assume that plants grow at a slow and steady rate throughout the day and night, Darwin and others found that they grow in regular nightly spurts, with plant stems elongating fastest in the hours just before dawn. See video of soybean sprout growth at: http://www.biology.ucsd.edu/scicomm/video/bigbeansprout.mov
"Plants actually grow rhythmically," said Kay. "Some plants, like sorghum, have the ability to elongate a centimeter or more each night."
Why plants have evolved mechanisms to grow rhythmically at night or in the hours just before dawn is a mystery. But a similar interplay of light sensing, plant hormones and circadian rhythms that leads to a pronounced rhythmic growth by plants during certain seasons and when shaded by other plants has a clear survival value.

From what I understand from reading both of your posts is, in a way you're both right.

The both of you stated that at night the stem grows or "stretches". Due to its biologic adaption for survival. Meaning, grow taller to ensure it wins the battle for light.

Both of you in way or another has said that new foliage does not grow at night.

So I interpret this as there is no new foliage growth, due to the plant using all it's stored energy to grow/stretch the stem.

With that said, you would assume that the roots also do not grow at night, because all the plants energy is focused on the stem.

This makes since to me since I've seen a lot of posts around here about when going to 12/12 the plant stretches and root growth slows down.

But hey what do I know
That's just my :twocents:

I started the ones I have going now with FF OF in cups. And let them go with the rest of the harem 24/7. Under the T5 they are doing fine in my opinion. No nutes for a month straight water, and let the girls be girls (hopefully they all are all ladies, but I need a stud to do some hanky panky with a momma!! ). I might, just to see the reaction nute stress them a little after the third or fourth node. These two were just moved from cups.

AHA!!! I may just be heavily medicated from smoking some of the last of my Trainwreck(EXCELLENT first-time strain to grow-imho) right now, but I think I may have just come up with a possible solution to those "great debates" on cannabis. This is the idea I plan on running with from now on. It won't put the debates to rest, since opinions and science often clash, BUT from now on, while I will still seek opinions and advice on ideas or concepts that are new to me, I will(as much as possible) use a large rubbermaid tub or small closet/cabinet and simply implement this new idea into that 1 plant. Proof is best found independently, again imo. So come JAN1, when I move to my new home with the extra bedroom that my beautiful, understanding, loving wife has so graciously allowed me to designate as my new grow room, Each new grow will be accompanied by an informative thread, open for discussion, where I will post results.

I already have a few experiments in mind and it will take time to accumulate info. However, once up and running, I am planning a monthly harvest so the info gathering should pick up pace.

Great idea! :thumbsup: Looking forward to following up with you on it.
