The amount of money you will spend on those cute things you might as well buy a proven LED The GlowPanel 45 LED Grow Light - led grow lights -Sunshine Systems from what I have seen in person, they talk up the flowering abilities of these things. I have not personally seen them on cannabis though, just tomatoes and peppers. I saw this light grow four tomato plants well over 5 feet tall. seriously lacked once flowering began though. Might do better with a whole shitload of em.
on that website you sent me it's compared to a 250w hps, and that's not too much light in the first place. i have 212 watts of cfl on two plants and i'm about to switch cabs for flowering and i want to add one of these LEDs for the flowering aspect as well as the cfls.
They lie, no way that will compare to a 250 for flowering. Doesn't mean it doesn't work though. LEDs do pretty amazing things as far as vegetative growth is concerned. I ordered that light and should have it by the end of the week. If it works out I will convert my veg tent to LEDs.
Key to buds is the right amount of stress. LEDs tend to be on the less stress side making the plants too comfortable. We are recomending cooler night temps more like in nature to make sure the plant know that its time to flower. After you figure that out you just need to make sure you limit the rest of your costs. How expensive is the tomato you are growing? That number comes from electricity, Nutrients, and mostly your time. Bob
