I have a few questions :D

Okay so ive got a 2.5'x2x2' (HXLXW) cabinet and want to do a SOG with lowryder purple jems i wanna fit around 8 plants in there can i use 3.5 litre square pots? im using a 150w HPS can i use this from seed? and i wanna yeild atleast 10 gram per plant does this sound doable? thanks for reading hopefully you will know the answers

need more light and you will need more room on top cause your light will take up alot of room if you have it close to your plants.

why do i need more light? 15,000 lumens should be sufficient and with a 150w HPS it can be 4" away from the tops of the plant as long as heat isnt an issue this is my first grow and also i cant really afford more light im hoping atleast 10 grams per plant tho
