    Hi !

    I read a lot about growing and the right type of lights. I understand that the spectrum etc needs to be right, but I have a question. My situation is a bit particular since I would only need a plant or two, not more.

    Is it possible to grow weed under "classic / normal" growlight, the used to grow tomatoes and stuff ? For example, I found this one on Amazon : https://www.amazon.fr/Relassy-Crois...1HQ31HV5XK1&psc=1&refRID=Q08Y8TGMK1HQ31HV5XK1

    For ONE plant, with LED, do i need more than 45w ? does this kind of lamp work, even for flowering ? Thanks for your answers !

    It won't be enough, I read somewhere that for 4 plants around 1000watt led would be enough, so do the math

    Lighting needs are really not figured by the plant as plants can range from very small autos to gigantic sativas. Lighting needs are generally figured by the size of your grow space. However, 45W is not big enough to grow anything. It would work for a couple of weeks while the plants are very small, but after that, you are going to need something substantially larger. LEDs vary widely, too. You will want to look at the working watts--a 1500w LED does not put out 1500w of light.

    4 plants? It looks like only one plant is asked about. The math is simple if I understood the question right. 4 plants for a 1000 WATT led? :rolleyes:
