thinking of setting up a little grow soon, just have few questions,
what is a contactor relay, do i need one for 2 x 125watt lights + 400watt hps
also, when taking a cutting, how long after taking the cutting would you wait to flower it?
You want to root a cutting for 2 weeks, then grow it to the size you want before flowering, keeping in mind she will triple in height during flowering.
A 400w HPS should be 15-20 inches above the plant tops.
AK-47 is a high-yielding, high potency plant. She will grow as high as you want.
