In the future, you should replace these lamps with something more efficient and of high quality. It is best to use special soil, because if you use ordinary soil from the garden, it will not be so fertile. Also keep an eye on the temperature in the room (Basement, in your case). If you succeed, then I advise you to update your equipment soon. For example, use more quality lamps or even use different grow tent kits . I hope you succeed, good luck!
