2 weeks and theyre 20cm tall? How far away is the light?
Edit: get the 400w instead, Im growing 4 plants under a 600w HPS in a closet - 2.5ft wide, 2.5ft deep and 5 feet high, and Im only just able to control the temps. And dont put a sheet of glass under the light to try and make it stronger - it doesnt. Glass absorbs light.

The room is beening vented via a 125mm ruch fan connect, and a and ocilating fan in a fix possition drawing air in. The plants have 50cm of growth room so i got to keep them short, anyone Rating: 5
