hi all

is the perlite needed to a ph 7 sterlized soil??
i have heared so many diferrent opinions in lighting could someone tell me what would be the best lights for a 4x4 metres room???for 1 plant???
with a ph7 sterlized soil will i need any fertilazer???
if yes what characteristicks must the fertilazers have ? {what in growing and what in flowering}

PH of 7 should do for soil not hydro though. Just wondering why you would want to grow one plant in a 4x4m room? massive waste of room. But to light up a room that size i would recommend several 600 or 1000watt HPS but for one plant even a single 400watt HPS would do. Oh and yes use some nutrients most are the same i recommend Nulife Technologies, FoxFarm and Advanced Nutrients and normally they come in a 2pack of Veg and Flowr. Peace Man and happy growing.
