A plant calls for part sun, how many hours is that?
I've been bought an Orchid about 2 months ago, it's perfectly healthy, but, it appears to be growing Green roots at the bottom of the pot, I was wondering why? Any advice would be appreciated. Thank you
If the pot is clear as shown the roots are probably trying to photosynthesize light. Place the pot inside another pot to discourage this.
I would remove the plastic pot and repot your orchid in a suitable container.
The roots of an orchid need to have air circulation.

In a green house can any other source of light be substituted for sunlight?
Absolutely -- what type of lighting depends on the type of plants you're growing. This article will walk you through the various options of artificial lighting available for growing plants indoors:

Is there any difference between LED lights and LED grow lights aside from colour?
There are two typical styles of LED used for horticultural purposes... COB and Cree. This is because of their longevity, spectra, and ability to be driven at about 55 to 60 percent at most efficiency.
This means that in the long run, using these LED's over any old diode will save you time, and money. It is also important to know how they are driven. Most standard household LED's are overdriven, and waste much of its energy in heat production.
I use LED for myself. It is a brand called KIND. I have many tropicals that will not survive my location. I can keep them all outside over the summer, but during the winter, I need something that will not only keep my trees alive, but will keep them growing as if it were a tropical environment. There is a technique to driving LED's correctly, and often times, it is not so expensive that you have to build your own unit.
If you just want to build one just to be able to do it, I would recommend asking many of the home builders how they do it. Most run on a 12 band spectrum, with very specific nm diodes. This includes infrared, and UV A, and B.
Hi there, I am reading a lot of 'no direct sunlight' rules for a lot of the indoor plant types. However, I live in the UK and currently are in Winter. There are many cloudy days and I am wondering if sun through a cloud still counts as direct sunlight or whether it actually has to be sunny in order to count as direct sunlight. I have quite a few plants in my room but the window which is quite large is south facing so not sure how to position the plants that do not like direct sunlight on cloudy days. Thanks! Jose
For plants such as this, it is best to let them sit in the room, but not next to the window. The room should be bright enough to allow for proper lighting. Giving plants that can't tolerate full sun will likely burn them, and kill them. Alternatively, you can put them in an east facing window, where they will only get a little morning sun.
I just bought a foxglove and it says part sun. Is that considered full sun for a limited amount of time???
Partial sun is 3 to 6 hours of sun.

Can you maintain the plant trough winter with grow lights?
Absolutely! I have a 4x4 tent that allows me to produce tomatoes, carrots, onions, and any other things that I want to eat through the winter! There are many options available, and I personally prefer LED. With a good LED panel, you can save on electricity, while giving plants a full spectrum (to plants that is) light source with no wasted spectrum. These also produce much less heat than conventional bulbs, although the old methods are still tried and true, at the cost of heat and power consumption.
What is the size of the area that you are trying to light? This will give me an idea of how much light you will need.
