That's totally normal to get all of those new branches from the plant you topped. That's what a healthy plant does. The DF are looking good. Congrats on all of the new seeds. And, that light will make buds. It just won't give your plants the preferred wavelengths of yellow, orange and red. It won't reach it's full potential. There's a reason why plants prefer blues during veg and oranges during flower. I will talk all about it on my next video. And, be looking for a package in about 4 or 5 days.
looking good buddy, i would suggest 2 clones of each, as not all clones will go.....on a normal basis you will lose one or 2 so take a couple extra, and as for the explosion of growth, i have been noticing it as well with the addition of another light in both of my tents, keep up the good work and thanks for the shout out:)
