hi i use these pots designed 4 bottom watering (walmart) i usually water from bottom when using chemical nutes, organic feeding and flushing from top. i think these pots rock regardless of how ya usum. imo, watering from top is a little better cause ur roots will grow closer 2 the top of the pot and more roots is more bettah:thumbsup: hope this helps, good growin:jointsmile:
