I am a relatively new member of this group, and I looked over the most
recent messages before I decided to write this post. I have a question
dealing, specifically, with the general 'household plant," and the
degree of sunlight that is warranted for such plants.
Question: Is there a means by which one can identify those plants that
require varying degrees of sunlight? Is there a mean of relating this
to the type of leaf, for example? And, if this is true, is it also
true that the typical "household plant" lights that one sees in local
stores are almost as effective as natural sunlight? If the answer is
"yes," or "perhaps," then would it be normal to think that one should
use such a light during the normal "rise and fall" of the sun
throughout the day, for example, during those days and weeks of little
to no sunlight for various reasons.
You might Google, question dealing, specifically, with the general
"household plant". It's true you know about JSB. His hovercraft IS full
of eels. What are you wearing for Beltane's Day? Don't over dress;-)
I apologize, Billy; although I agree with your dogmatic views about
the present administration, I don't get the link between what I typed
and then how you chose to respond. Perhaps there is something like an
"inside joke" going on within the group?

Yeah, about 29 hours more and the days will start growing again and,
after a speed bump called "winter", blessed spring, and rebirth.
Hallelujah, brothers and sisters, hallelujah. A new year is coming up,

There is no such rule that I know of. Many houseplants come from jungles etc
where they naturally get filtered sunlight but still some need more than
others. Most benefit from at least strong indirect light and many benefit
from some sun. You cannot grow anything but fungi in near dark. How much
light each plant wants is dealt with in good books on the subject. Some are
rarely seen at their best or never flower because they don't get enough light.
And, if this is true, is it also
Well no because the sun is much more powerful, it takes very strong artificial
light to be as bright as the sun which chews up lots of power. Normal house
plant lights are useful as a supplement to natural light if you don't have
sun-facing windows but it would be rare for them to be able to replace it.
Also the brighter the light the more heat it produces which can be an issue.
Some types are more efficient than others but all produce some heat. There is
also the factor that the strength of light falls away quickly with distance,
so the plant that is right under the lamp gets way more than one at the side.
If the answer is
I don't think the timing makes any difference.
Your answers were extremely helpful.
I only hope that I am replying using the correct protocol for this
Thanks for taking so much time in responding. Your answers were/are
extremely helpful. I asked the question for several reasons; but one
main reasons was my "re-newed" interest in house plants and my recent
purchase of a bulb to use in home, as I suggested. But, I do see your
point. It is interesting to note how the "common house plant" has been
That may be an answer for some sorts of plants but timing is certainly
critical for many. Many plants will not even flower unless the timing

Depending on the house hold plant you have . unless of crouse is ver
special. house hold plant donot require alot of light. the only proble
would be with watering. l have notices that during summer my plants ten
to weather off. leafs turning burn. l tend to keep them in the shade
where do you leave
It depends on the plant and what you mean by "a lot". I have seen many more
house plants that were not their best due to too little light than too much.
Sorry I disagree. Watering house plants is one aspect of their culture that
is fairly easily controlled.
What sort of plants? What is your summer like? Do you have air-conditioning?
This could be not enough humidity, in their natural environment many house
plants like much more humidity in the air than humans find comfortable,
especially when it is hot.
l tend to keep them in the shade.
I live in eastern Australia. The summer is very hot and often humid. The
winter is cool but does not snow.
I think your question is too general, you need to look into the
specific requirements of the particular plants you are trying to grow.
Sanseveria needs very little light, radishes need a lot. African
violets, somewhere in between.
Most of my reading lately has been for aquarium plants, they do well
with fluorescent lights.
Plants, in general, need mostly red and some blue colors in the
spectrum, the "Gro-lux" tube is designed to provide these. A problem
I had with them, they just don't look the way I wanted things to look.
Some time ago the standard recommendation was a combination of cool
white and warm white bulbs. I also remember somewhere on the web
reading that in a particular trial cool white was as good as anything.
It takes a lot of light to equal the sun light for intensity, mostly
plants selected for growing indoors are low light plants, many would
burn if put outdoors in full sun. Most are also tropical plants,
which are day-neutral, that is not affected much by the length of
light period. I'd start with 12 hours, see how that works.
Incandescent grow lamps are overpriced and underpowered, but do
output a pleasing to the human eye spectrum, plus lots of heat,
possibly too much for a plant's health. Fluorescents are better,
high intensity discharge halides or high pressure sodium better
still, though the latter two lamps require specialized ballasts
26 watt (100 watt equivalent) cool white compact fluorescents
are cheap and work great for small plants, with no special hardware
needed; I have a test impatiens that's blooming heavily under a desk
lamp with a 16 watt cool white CFL bulb (60 watt equivalent).
Starting point would be anywhere between 12 and 18 hours on
for every 24 hour "day."
Generally speaking - no, other than cactus and other succulents which love
sun. Ferns of course like dappled light to bright shade and humidity. You
