a regular light bulb-no.
Yes you can use it.
sure, it emits light as well as heat. the light from a regular light bulb is not sufficient for photosynthesis but may have an effect on photoperiod which can be a good or a bad things, depends on what you want to grow
Only if you buy a "full spectrum" of "grow light" type of compact bulb.
no you need white lights not yellow buy the energy saver ones. that look like a spring.they are the best.
If you use fluorescent lighting you will receive flowers on your plants. A regular light bulb will not do the trick. Buy a cheap shop light fixture and put in two long tubes one cool and one warm. Yes- artificial light can be used to grow plants, including flowers. A light bulb may not make enough light. Search for grow light or plant light.
Many of my customers use a 6500K or 5000K CFL lamp to replicate natural sunlight. They will grow strong plants if a oscillating fan keeps the plants moving as they grow toward the light. There have regular medium base for screw in fixtures. Order from Bright Commercial Lighting on their Facebook page, get the 105W Longstar or for real little plants 12W top spiral longstar will do.
they grow better in regular sunlight because it is more natural
Depends on the plant some grow better in darker places but if it needs light go with the sun it's free
Over time, the heat produced causes the filament to grow thinner. This causes the light bulb to grow dim.
By studies, plants grow underneath natural sunlight better.
Actually, light from certain lamps does help plants grow. In almost any garden shop, you can find germination kits that include little containers for the seedlings and a special bulb that helps grow the seedlings. In extreme cases, seen often on the news, marijuana growers actually grow entire "fields" of plants indoors using Grow Lights. Right now, in many of the catalogs you see like Brookstone etc., there's a new product that's designed to grow herbs for the kitchen?and it also uses a special Grow Bulb (and hydroponics) to achieve this. The trick is to have a bulb that covers the correct spectrum of light!
