<span class="link_user">@Odin9</span>, I haven’t made it to flower yet. But for my seedlings I ran the light at roughly half height of the tent on 40-50%. Veg has been around 36-40” above the plant canopy at 100%. Now I’m currently running about 24” above the canopy at 100% in veg. I’m mostly just playing with the light and learning it. If I could go back and start over I’d probably run something like this. Germ/seedling 36” @ 25/30% early veg 24” <span class="link_user">@45</span>/50%, late veg 18-24” <span class="link_user">@100</span>% then make adjustments for flowering.
