If I had over 2K to spend I would go for two of the new the Pro-Grow X5 from Hydroponic Hut. Those LEDs look like beasts...

I have a Pro-Grow 260 (190w) and 4 x 65w CFL in my 90cm x 90cm x 150cm tent. That's 3' x 3' x 5' in American...

I think this is just enough for my tent and the results are looking good. The LED lights are expensive but they do the trick. They are very good lights.

I also started growing auto fems this time and I think I will always grow autos from now on. Fast finish and a good yield. You can't clone autos... Just to let you know.

With autos you will have to do everything from seed. Autos don't depend on light cycles, they flower based on time. It is not possible to revert an auto one it flowers.

I think what is very important with autos is a good veg stage and at least 2.5 to 3 gallon buckets if you are going to grow in soil.

Don't worry about re-potting with autos also... After the seed germinates put it directly in the final bucket. The autos like to feel their container size and grow accordingly.

Anyway, good luck with your hydro set-up. I really don't know much about hydro as I am a soil grower. I think the plants prefer the soil living... It's more natural, but sometimes less yield.

Good luck with your new adventure and don't forget to keep a good grow diary for us all to see.

Take care
