Description
The specific flowering bulb Groxpress Sylvania 600w lamp
The Groxpress Sylvania 600w flowering bulb is designed to produce a specific color temperature of 2000k, which is what your plants need for the flowering period when grown indoors. This color is rich in red and orange tones that simulate the autumn sun and induce natural flowering in plants grown under this light. It also increases yield when compared with mixed bulbs.
The Sylvania GroXpress Lightbulb has a useful lifetime of around 4 grows
This HPS light is made by one of the most renowned manufacturers in the cannabis sector due to the quality of their products and competitive prices. The light flow generated by this light can reach up to 90.000lm, producing 600w power with a service life of 25.000-35.000h, which should last for at least four rounds of plants, as it should only be used during the flowering period. These types of HPS bulbs have an E-40 socket that’s easy to connect to your reflector.
This bulb has a specific lumen spectrum designed for the generative period
If you’re looking for the best possible results, we recommend using a specifically Sunmaster MH Veggie Growth Lamp bulb during the growth period, as these types of bulbs have a specific lumen spectrum designed for the growth period, increasing total yield by using a specific bulb for each period rather than using a mixed bulb. You can also use both of these bulbs with electronic and magnetic ballasts, getting larger yields and efficiency with the electronic ballasts.
Technical details:
- Visible light: 90.000lm
- Color temperature: 2.000
- Service life: 25.000-35.000
- Rounds: 4 rounds of plants
- Recommended period: flowering period.

How far do you put it from the tops in flowering? I'm testing it out and don't want to burn them. Thanks!
Translated from Spanish
¿A qué distancia la ponéis de las puntas en floración? Estoy probando y no quiero quemar. ¡Gracias!

One AK grew to almost 1.2 m, and it wasn't even the biggest I've had. It runs a bit hot, yes, but the result makes up for it. I recommend it if you're looking for a good yield!
Translated from Spanish
Una AK me dio casi 1.2m, y eso que no era la más grande que he tenido. Calienta un poco, sí, pero el resultado compensa. La recomiendo si buscas buena producción!

Does it work for veg and flowering or is it just for flowering? The thing is, I need one for the whole cycle.
Translated from Spanish
¿Sirve para vegetativo y floración o es solo para florar? Es que necesito una para todo el ciclo.

Is it compatible with an electronic ballast? I was using it with a 400w one and I have doubts.
