    When to replace your HPS bulbs

    I'm not sure when it's time to replace my HPS bulb. I traded a guy a bunch of grow light equipment for some cuttings. Some of the bulbs were obviously used and some appear to be new or at least used slightly. It's easy to tell when to replace a MH bulb, the ark chamber gets blackened. In the...

    Newbie planning on building micro nano grow box

    Hello guys, I'm newbie here, I've read a lot of stuff about growing. And decided to test it by myself. The only problem I have is space...

    315W LEC vs 300 HLG Quantum Board

    Nebula Haze completed her 300 HLG QB vs 4000k Hortilux Bulb (Vertical Alignment) and results are below: Note: shes admits that no defoliating was done and therefore the LEC lower buds were mostly thrown into trim and that reduced the weight, which also in turn makes smaller buds and lower THC...

    Building a fixture with 5w Bridgelux 45mil chips.

    Hi everyone, I am going to build an LED fixture consisting of 5w chips. These 5w chips contain 2x2 45mil diodes. Each one of these diodes, if packaged individually, are sold as 3w chips because they are rated at 700mA (3.4v X 700 = 2.4w). In a 5w (2x2) package, they are also rated at 700mA...
