AsNoriuanswered grow question 7 months ago Its all about penetration, 300W wont go 1m down anyways, plus they are ussually bigger by size, will it fitt ?
This girl looks like 100g+ easy if all goes well...
Maybe smarter to lolipop her a bit, clear bottoms, 2 feed deep canopy is still doable even with 100w, just spread the plant wider, selective and WISE defoliation is an option too ..
