Could you post the size of that tent again? Hope you don't mind im copycatting you.I got my 240W blackstar and ive bult a 5ft Tall 4ft wide and 3 ft deep box built and I'm hoping to place one Think Different in a 5gal bucket dwc using 3 part GH nutes and potash based root enhancer.
i also am interested in seeing what a single 300w+ LED can yield. Perhaps use the second light to boost the other tent instead and move the polar lights there. Is anything flowering in the other tent at mo?
