Soaked Rockwool cube in Distilled water Ph'd at 5.85 until the actual water from the rockwool cube read 5.85 after being squeezed out some ( I know your not supposed to do it but I've done it this way every time without any problems) I then place the seed pointy end up in the rockwool cube and then the cube into the humidity dome with the top vents 1/4th to 1/3rd closed on top of a heating mat. The hydroton is also soaked in a strainer which sits in a larger bowl until the water reads 5.85 and much of the dirt has settled to the bottom of the bowl, I repeat this until the water from the hydroton becomes more clear a the bottom making sure to wash away as much as possible. I use 2 controllers to control everything, Exhaust fan ( exhausts to a separate room ) 3 Manual fans, humidifier, Dehumidifier and a led light, I only use distilled water for the entire grow and use a Apera 3719 for water testing, Each bucket has a 6 inch cylinder air stone attached to a shared 1189 gph air pump, a pump inside to get rid of old nute water and is also attached to a tote outside the tent to replace it, all pumps are controlled using smart plugs and a app on my phone, this really comes in handy when they get to big to move around, Each bucket also has a sample port and a level indicator tube with zip ties every half gallon to know how much they have eaten/drank, its also used for feeding and ph adjustments if need be
