how many watts do i use wen starting growing and how many watts do i use wen im flowering? i keep gettin told but i forgot, any other tips and id be grateful. safe.
u want atleast 1500 lumes per sq foot during veg and 2500 to 3000 lumes per sq foot in flowering. watts dont mean a thing in real life, there just a way of makin the lumes u need but as a rough guide 50w per sq foot is the accpeted number in flowerin.
