any ideas on a simple DIY growbox/tent

the light that is being used is a 150 watt hps. the plants are being grown using LST. they have been outside all summer but with fall approaching i was to bring them inside.
any ideas would be appriciated.

PS i dont know the strain they are bag seeds

150 watt HPS seems a poor replacement for the good ol' sun.

yes i would go with a bigger light or just let your lil plants flower in the great outdoor but if you do want to make a lttle grow tent i would suggest just make a pvc box and wrape it with black and white panda plastic then one of those little zipper doors and there you got the room bu youll need alot of ventalion so reamber that as well
