im about to grow 5 plants in a rockwool hydro setup, n i got a few question.
I gotta still check the PH/PPM/EC of the tap water in my area, but once i figure out the starting PH/PPM/EC of my water, i wanna know:
1) What is the best EC for maximum nutrient uptake? Between 1.0-2.0? Also, how do you go abouts lowering or raising the EC to the desired level?
2) When adding the nutrients to my water, and lets just say my water has 180PPM (hypothetical), do i have to subtract 180PPM from my desired PPM total, or just add to the 180PPM.
~For example(if im not making sense), just say i wanna have a desired 300PPM for my seedlings, but my water already carries 180PPM, do i make sure to add only 120PPM of my nutrients, or do i just add the whole 300PPM, giving me a total of 480PPM?
i appreciate the time, and if anyone has any tips or suggestions for a new hydro grower, or is willing to help me out where needed, please let me know...im willing to learn from the best. this isn't my first grow, just my first hydroponic grow, and im really interested in learning how to grow hydroponically, to the best of ones ability.
o one more thing...instead of draining my nutes straight back into my res, i was thinking about keeping it seperate, that way i have more control over the used nutrients PH/PPM/EC left over from the feed, and can get a little more information on whether my plants are eating everything or being deprived. I figured i could also make subtle changes to the solution before adding back to the res...good idea? bad idea? or just pointless in the end?
f.uck, i havent typed so much since highschool...haha...time for a vape!! cant thank them germans enough for the volcano..haha...hope to be hearing from all you potheads!
thanx.
