Why not? The guy from the other tread is a first timer as well. It is just a question of setup configuration. Everything else is the same. You should have another look at his thread. You will achieve significantly more yield because the use of light is so much more efficient. You get 360 degrees of useful light. Overhead reflectors are wildly inefficient. In fact, many people don't use them as they reflect heat better than light.

The question I have is can you remove the reflector from that cooltube you ordered. Usually you can but sometimes the reflector forms the back half of the cooltube making it impossible to remove.

Just an aside, you understand the importance of keeping your bulb clean, yes? Before putting it into the socket clean the bulb well removing any / all finger prints. If you install the bulb with finger prints the oily buildup on the bulb creates hot spots on the glass which can decrease the life of the bulb and even lead to failure of the glass. You likely know this but just wanted to add it FYI.
bigsby Reviewed by bigsby on . Can I vent this? Hey so this is my first grow and i wanted to buy this Grow Tent and 400w HPS kit but i'm not quite sure how to set up the ventilation. is it ok if i just set up small cfm fans without ducting? i don't want heat to be an issue, but at the same time i want to keep it as cheap and simple as possible since the tent and light were pricey enough :) any help or tips appreciated! cheers Rating: 5
