hum, it might work how ever its a bitch you donā??t no the strain. 6 inch of soil isnā??t really enough but again it might do. i think you may find the seedlings will stretch allot 2, as the light isnā??t very bright - it might be wise somehow lowering your light for the time being. Your going to have to train them like bitch in a few weeks, ul need to keep everything as low as possible.. uv got at least 7 weeks be4 u can flower successfully and for all we now they might be some wild ass sativa.. take it as it comes man but dont hope for much just yet!
