Hello- I'm planning to start all my garden plants from seed this year. I'm wondering if I can start the plants using artificial light only. I am planning to get a 4 foot fluorescent lamp with 4 tubes in the 4000k to 6000k and have it on for about 15 hours a day and locate it in my boiler /laundry room which stays at about 70 degrees. There is no natural light in this room so I'm wondering if this will work. Any suggestions are greatly appreciated. Thanks !
