Cheers for the advice Jondamon, so lets say i do go with 2 400w or even 2 600w lights per 6 x 2.5 scrog how long should i be expecting to veg? to fill the 2.5 x 6 screen? lets say 18-20 plants are used for one 2.5 x 6 scrog. The plants would be grown from seed so im looking for a vague estimation of how long it would take? weeks? months? ect all from seed.
Thanks.
