i don't, at least not yet, i think there are some nute products that claim extra root growthDo you guys use any root promoting supplements? I suspect the weak root system I found previously probably isn't helping them to grow faster. Any thoughts?
the only specific thing that comes to mind is getting more oxygen to the roots
a good soil mix seems the best way
i have seen some use a bit of hydrogen peroxide to 'feed the roots'
i haven't used it, and would definitely read up on it before trying
also used to clear up other root troubles
i do use molasses tea as part of my feeding, 1 tsp per gallon of water
this feeds beneficial bacteria in the soil, best used with organic soils
