Heya! Super new to growing and just learning how to get set up and wanting to ask for some feedback on these lights. Mainly just looking to use what I have available to get started and was curious of these lights would work. Obviously I’d replace the black light bulbs but would these halogen light fixtures be enough? The bulb length is 43cm.
I use one of these for the first two phases in a cannabis cycle, seedling and first growing stage. I have two Phillips MASTER PL-L with 4000K / 55W / 4800lm. They are very good for root develpment, but the low wattage means theres not enough oomph for bigger plants and your yield will suffer. Your regular growlight comes with 200W+ and different color for the flower cycle.
I'd say they are great for your first plants, but you will eventually upgrade.
You'll probably find more bulbs if you search for 18 inch bulbs rather than the metric measurement. As far as brands and color temp, I'd defer to the other poster.
