Simple question about bulbs.

Just need a simple answer. I grew 3 females last year outside and they faired well. Lighting wasn't n issue.
I just need to know an effective inexpensive full spectrum bulb for just one plant.
Dats all. Have a seedling I'm gunna have to make an inside plant.

For one plant you can get the screw in type LED’s and remove the plastic cover on them just make sure you get the right spectrum. I prefer 3000-3500k and just get a few of them and keep close to the plant. Is it the best no but it will grow you some fine smoke if that’s what you’re looking for without breaking the bank. Heck they can be found in the states in the dollar stores.
