I am new to this forum and I hope I could find many new friends here.
Recently I bring some little cactuses to my home.But after a week I
think they are droopy.
Already I have not access to sun light in my home and I think this is
why they are not succulent.
Now can any one tell me how can I provide artificial light for them? Is
regular florescent lamps good?what about type (yellow(like sun) or
white(like moon)) and power ?
and if not what should I do?
Also I can add their picture if it is needed.
If your cacti are dry and droopy that should be ok. If they are wet and
droopy they may well be suffering from root rot, and unless you can cut
off the living part and reroot it, you could have lost the plant.
At this time of year most cacti should be kept absolutely dry and cool,
on a light (south or west-facing) windowsill. But they should not be
allowed to get exposed to frost when the curtains are closed.
As to light, you can spend a fortune on suitable lights. Commercial
growers choose special fluorescent or other types of lamp. For home
use, almost any decent white or near white fluorescent lamp should do.
it should be kept as near to the plants as possible (a small aquarium
with a light would serve for this purpose). But really there is no
point in trying to push cacti into growth when they should be resting.
In fact, unless small cacti get a dry and cold rest over winter, it is
very unlikely they will flower. Give them the proper conditions, and
you will be rewarded!
With the priviso, It depends on the cacti and how much area they
cover, lets start;
The bottom of this site has a bit of info on some of the common
lights available, Metal Halide (MH), Higt Pressure Sodium (HPS) and
Fluorescent (Fl) http://www.topbulb.com/find/grow-lights-bulbs.asp
and the CFL such as here:
I would go w/ the HID for now, that will change in the future as LED
and some of the newer super lights get in production.
I do not recommend a 2ft Fl, no lumens to speak of. 4 ft shop lights
are ok, but at a basic level, the color is not really important,
lower temp (yellow) is ok, bright white is alright also. Fl is my
last pick unless it is a 4 tube or better T5HO. even then shop smart,
the indoor garden stores are too spendy. Shop here:
For a small area and a couple of plants, a 68 W CFL such as you find
put on a spring clamp will do well. It has 4200 lumens, enough for a
low light plant in ~ a 1.5 -2 Sq Ft area and you can put it close
( law of inverse square). I got one from HD in a bargain bin < 20
bucks, here is another http://www.1000bulbs.com/product/8254/FC85-S50OD.html
. As I said these works fine for a 2x area. just follow the plant's
After the 68w-85w CFL range , any boost up in Watts ( w/ exceptions)
is going to have a mogul base ( larger screw in ) and usually some
sort of ballast or a self starting ballast, adding to the initial
cost but now we are at the entry level for HID lighting. so really go
HID you can use it for your orchids later. as you may have seen in
the CFL link above, these are 80$ w/o shipping to 130$ at a store.
For the same price points Home Depot, many of the Ace Hardware chain,
and Amazon have a 70w and a 150W HPS they sell as a security light.
HPS has a spectrum advantages over MH and FL but new stuff is coming
up all the time.
70W~ 6400 lumens : http://www.shoplinkz.com/p/Intermatic-70W-High-Pressure-Sodium-Flood-Light-120V-FL070HPS
150W~ 16, 000 lumens : http://www.shoplinkz.com/p/Designers-Edge-L-1760-150W-HPS-commercial-Flood-Light
These are affordable and provide the horsepower you need . Be warned
you will have to configure a mount, adjustable is best and know the
best height for you plant(s).
LED need to come in at around 5-10 W per LED and they come down in
price. Many from overseas are nothing but cheap recycled traffic
light. But know the LEDs do work for plants.
