I also noted that the coverage area was about 5 times grater than before. I had to install some ducting to help with cooling as the light was much hotter than what I had in the past and after moving the air pump to the outside of the tent I am only 1 degree hotter then before. The move to the new lighting has given me the option to really start expanding with more plants so I know that I will be busy in the next few weeks adding more hydroponics systems to the grow tent and may even finally see some tomatoes. |
i dont want to butt in but i dont understand, why would you use metal halide and
hps lamps at the same time. when you can buy a dual spectrum 600w or1000w lamp.
you can also buy them with cool tubes or units that have ducting flanges on to vent the heat away with an extraction fan from the lamp itself, instead of the room.
i have never liked metal halide, the spectrum is the very top of the vegetation scale, it will cause very tall and thin tomato plants etc, the hps is at the very top of the flowering scale. it is like changing seasons, use the metal halide to grow the plant, and once you want to bear fruit swap it with the hps, you have tricked your plant in to thinking that the season or time is right to bear fruit. led
lights are a waste of time, to copy our sun you need very strong light with lots of power behind it.
