With larger plants you need professional lighting, like that used for hemp. I have no plans to start early, my lights are used in the spring for tomatoes, peppers, and other seedling crops, melons, flowers etc. I don't have room. even with 10 bulbs x 4 foot lights, and 3 bulbs x 2 foot florescent lights. My neighbor grows hemp, and I think he uses halogen lights, extremely impressive set up. The lights do not have to be close. I may one day get some to grow citrus. I will talk to him about what to purchase.
I rooted cuttings last winter, it was a mess as I needed the lights as mentioned. I made due. For new plants started early I myself think 4 foot T5 lights with 4 lamps is perfect to give them deep green color. You can use more, or less, it will still work, that is what I used. I also have a T5VHO light (regular ones are HO), but a ballast blew on me last winter. I just bought a new ballast. It's very important to install correctly. Not easy I have to splice wires and such. I don't want to electrocute myself! These are high voltage beasts! The light was so expensive, and so useful, I'm going to fix it. I found the same ballast online.I have yet to install it I need some electrical caps, been busy, and don't need it for months.
