m0useanswered grow question a month ago I agree with Scrubbyjimbob in everything they say.
a incandescent light bulb is a poor choice for growing,
Your watering to much, and this will create issues down the road.
You can go to a dollar store and get some form of LED grow light or even a grow shop that sells CFL growlights that fit into standard edison base sockets "the better idea". I think they are called E26 or A1 style base here. But its almost universal. Should run you about 10-15$
As for watering. Only give them what the need when they need it. Your medium is going to dictate a lot of that and how big the plant is. Soilless mediums need more water and soil less so as they tend not to be draining as well. There are a lot of other points to touch base on. but if this is your first grow I would suggest reading some guides and getting familiar with a basic setup and the things you'll need and should expect.
