ok so im about to root some clones using DWC and i was wondering what i should use to down the ph and was wondering if i need any other solutions to the water. ive done this before but i used lemon juice concentrate to lower the ph but it isnt stable enough.
Also i was hoping that someone can give me some tips on how i can make my trays some legs for they are not floating precariously which is how i had them last time. i have two trays and they fit perfectly.
here are some pics of the set up its still under construction.
