I haven't actually set up my Hydro system yet. I suppose I need to get a ppm meter.
ppm is a parts per million meter for measuring newts. I use the ppm stick from blue point I believe. it's easy and idiot proof. there almost required to make great pot not good pot. little guys my meter will read .4-.5 and bump them up to 1.4-1.5 I have some white widow in soil and I'm feeding it 2.4 nd its going great. the meter lets you know how strong your mix is by testing the water not just measuring out amounts.
no, 2.4 will nuke starter plants start off small with 1/4th to 1/3rd strength and work your way up to full. A ppm meter is to see how strong your mix is, thats it. say you add your water and newts and your leavs are showing they want more measure, add, measure. it will help you with free pouring too. In my soil app I have a big rez and I will free pour and check and pour some more untill my ppm is where I want it in that way it just saves time. I'm not sure how to help you, i dont want you to get off track.
Well all the newts that you have mentioned above are general hydrophonics newts. they work great for a hydo setup I have never myself used them in a soil app but maby it's worth a try. I thought you were goig to be using a diy aro setup? But to answer your question yes the mico,bloom,gro is a 3 part set that you want to use all togeather.
