# Time laspe trick for a plant/tree

Time laspe "trick" for a plant/tree

This might seem absolutely absurd, and I have minimal knowledge of biology/ botany, but I'm going to ask anyway...

Hypothetically, say you have a completely sealed temp/ humidity controlled box. You also use some type of artificial lighting {maybe like the bulb I had to buy for my turtle}. Could you place a plant or small tree in the box, simulate a 12 hr day, and have the plant grow faster?

.. and so this doesn't come up, not its not an "illegal" plant. I have a small tree that is to tiny to put in my yard, and a friend and I were talking about how we could get it to grow faster...

If this is a dumb idea, please delete the thread and send me a PM telling me so..

ramp it up to a 18 hr day.

Works for my 'other' plants. ;)

Would that make it grow faster..?? I figured a shorter day would give me more day's , thus simulating a "faster" year...

By that reasoning you could try off/on cycles of two hours each and really make the years go by. :)

Plants need food water and light. You can control those and make the plant think it's in a sunny paradise. Nice long days is best for plant growth.

I can make my 'plants' think its a fast year by giving them 18hrs. for a few months and then drop to 10 hours and the things go into flower mode. Long before nature would have.

I understand that it needs ample amounts of sun/water/ etc to grow.. but by "shortening" the day's, would that create a small tree that was old {you could cut it open and see many rings} or what? Would it actually grow as tall as it should..

No.

Trees do not "age" the way humans do. They don't get older in the sense of the number of day/night cycles they see. Plants do respond to changes in daylength over time. In terms of fruiting for example.

For plant growth you need to understand the concept of a 'limiting factor'.

Plants need for the sake of example:

light (of the intensity they are evolved to grow in, ie., shade, partial shade, full sun)
light balanced to the correct color temperature
warmth
water in the soil
translocation of water from the roots to the stem to move nutrients up
available nutrients like nitrogen, phosphorous, etc. and micronutrients like boron
$$CO_2$$

When a plant encounters a deficient supply or the wrong balance of any one of these things it stops or slows down growth. One of the factors in plant growth is limiting how fast it grows.

A hypothetical optimal envrionment would be on in which none of those factors was limiting:

correct, balanced light source for 18-20 hours per day.
day/night temperature change
light air movement
correct water and nutrient levels in the substrate
ample $$CO_2$$
-->example: from combustion source, greenhouses use kerosene stoves sometimes.

This may not be feasible for your terrarium. But aging trees does not make sense. Tree growth rings are responses to limiting factors, not lights flashing on and off.... and you can sometimes see multiple rings from one year with abnormal weather during the growing season.

...They don't get older in the sense of the number of day/night cycles they see. Plants do respond to changes in day length over time...
Ok, thanks.. That pretty much answers my question.

.. and just for the record, here is the tree...
