What would be a good indoor grow light in wattage for tomatoes. [View all]

[Duncanpup]

I turned the back mud room into a grow area.
Now the questions i have as I’m a novice in growing inside are.

1- How long to keep the light on them daily what distance should the light be from plants from initial growth to when I have to stake them.

2 I’m wondering do you think maybe twelve hours is enough or too much trying to simulate long summer days. If I can figure this out then I’d have fresh tomatoes in winter.
If I can succeed at this attempt then I’m gonna build a small greenhouse try have fresh vegetables year round.

Thank you in advance.
