Looking good :thumbsup:

I'm just in the process of building exactly the same size cubicle as you! I haven't got very far yet, as I'm still in the process of boarding out the loft. I do have 90% of my materials though from a previous gardening adventure and a few trips to the (not so local) DIY superstore...

I only have a 400W HPS (SON-T of course) lamp for the same area. I know that's below the recommened level, but I did 1sm (10.8 sqft. = 37W/sqft.) with the same lamp before and the results suggested that I could have got a bigger area working, albeit if not as speedy in growth.

I also believe that the babies need room to develop

It will be interesting to see what kind of results you get from the extra light that you'll be chucking at the plants - I might even have to upgrade if your results are good :jointsmile:

Good luck with the project!
