figured i would start a thread on what i use for nutes. i seen all the other nutes sold at hydro shops posted and figured i cant be the only 1 on here using it. i use just the 20-20-20 for my veg plants and the 10-30-20 for my flowering plants(nothing else). i grow in coco coir mixed with some perlite. using these 2 tubes(1.5lbs each)of nutes last me a while and cost me about $32 with shipping. feel free to post what jack’s classic you use and if you use anything else from them or with them here.

Jack’s classic isn’t exactly intended to work with hydroponic setups. I’m sure it’s possible as many people have done it, but it’s not ideal.

Jack’s hydroponics line, however, is different in that it provides a soluble form of calcium (calcium nitrate) and a low urea and ammonium content.

Soil based nutrients tend to get a bulk of its N from urea instead of calcium nitrate, and thus expecting the soil to provide calcium through limestone (insoluble). Hydro based nutrients get the bulk of their N and all their Ca from calcium nitrate.

Jack’s professional hydroponics is a 2 part dry mix, where 1 of the parts is actually greenhouse grade calcium nitrate.

The simplicity of Jacks products really produces good, healthy plants for such a low cost per plant.
Tried Fox farms, which in all honesty worked okay. Basically went three bottles each run.. Just ran into few problems with deficiencies and at times over fertilization. Nothing a flush couldn’t correct. Each round of plants costed me many times more in comparison to Jacks which was probably less than 5 $ from start to finish, if that. No deficiencies to speak of either.
Tried organic, but found it to be inaccurate levels when I would brew a tea. Either too hot (yes I cut it with water), or not enough. Definitely an art to it which one day I will try again.

I just think for the value and results, Jacks products are up there. I hear dynogrow is some good shit, and perhaps I ‘ll give it a go.

Yes different products can get you where you need to go, but why spend more on watered down, fancy labelled, expensive bottles?

Only other stuff I use is botanicalcare silica, as it seems like it improves stem strength (unscientific clone experiment, want to look into it more), and fulvic acid which I’m just using up and don’t think I really need it.
