Sea Solids make plants EXPLODE in hydro!!

At 1/2 tsp./gal salinity, here is the sea solids ppms:


N (NO3-) 0.703
K 1.629
P 0.678
Mg 1.22
Ca 0.506
S 1.609
Fe 2.803
Zn 3.281
B 0.543
Cu 3.189
Mo 0.005
Na 1.154
Si 0.66
Cl 1.779
Mn 2.757


Sea-Agri adds N, P, K, Ca, Mg, and S in the hydroponics recipes on the web page. It's ok as a micronutrient source.


Sea solids CAN NOT grow plants as the sole input.

i did not have good results when I tried Sea 90 some 10 years ago.

I am much more educated in my hydroponic endeavors FYI, I use SEA 90, making mineral water for drinking, so, it's on hand, also I have a many year supply of nutrients to use up first

If I wasn't quite happy with finishing off my Emerald Harvest 2 part Bloom nutes (+ King Kola and Emerald Goddess), though I much prefer dry powders as I have a quality RO for cooking, drinking water, and mixing dry nutes. This saves money in shipping liquids built into their prices

I also have 4-5 years worth of Hydroponic Research V + B on hand. I like it very much, but I stopped using it for flowering long ago, plus I had 5 grows of EH Bloom on hand that I want to use up, now maybe 2 more grows left

I am also quite happy with NPK RAW. The individually premixed Veg and Bloom are supper simple to measure out and take up very little space on the shelf. To these I add NPK RAW Aminos, Enzymes, Microbes and Kelp for root development/seedlings, clones. Actually using them with the EH Bloom nutes, too.

While both veg products work well. I will be switching completely to NPK RAW BLOOM once I use up the EH: I probably have enough EH Bloom for at least one more grow

Now that aside, I would be interested in trying SEA 90 for clones, and maybe seedlings. Anybody have a EC/PPM formula?
