Grow by numbers

Optimal conditions for fast robust growth are not same as optimal conditions for ripening, up to you to decide based on knowledge you have and how best to apply it. Chlorophyll primarily absorbs blue and red wavelengths, causing them to be used for photosynthesis in the upper leaf layers, while green light is largely transmitted deeper into the leaf. This means that green light can potentially reach and excite photosynthetic machinery in deeper cell layers within the leaf, whereas the majority of blue and red light is absorbed near the leaf surface. Adding supplemental red and blue at sides can help the green that penetrates from top giving it a more efficient ratio of r🅱️g for bud development. Cranking the power up top will give slightly better penetration but the sell-off is keeping top cola cool, more radiation = more decay of trichomes. Balancing act. Good luck. Just my opinion 🤷 😌

Personally I don't bother with DLI or ppfd never have I go for the feel and look of the plant. I bet you some1 will pop up with an equation for you to try and swallow but you have enough Watts in there just dial it in and watch her rise.. Let's don't have massive penertration I would have it close ishh and turned down rather than hight up on full especially such a small space...
