i have some experience with mixing dry nutrients. i have used jacks pro hydro and mag sulphate to make an A concentrate and calcium nitrate to make a B. i have never been able to get it completely dialed in though.

this is a pretty nice write up you've done here. nice pics. i hope you don't mind a few questions. where are you ordering your salts from? what micros and amounts are you using? are you using any fulvic or enzyme products in conjunction with your feeding? what is your early and mature veg ec?

I ran the system last night and it worked beautifully. I just used a 5 gallon bucket to draw from as it was my first run with all 18 spray stakes working. Miraculously there were no leaks. I have a sediment filter attached to an inline filter on my intake side. I took some pics with my phone...

Well they're all hooked up. We will see how she works.

so are you feeding the same ec/ppm all the way through? If so what are you keeping it at? What nutrient profile are you creating with your salts?

Its hard to see whats all going on in that pic. Looks like a vert cage setup. can u take one of the buds with the lights off?

You have any nice bud shots using your hydrogardens mix?

are you still feeding with jacks. I remember bs'n with you a little bit at the farm about making concentrates out of Jacks.

Im still watering by hand but planning on firing up the sprayers next week. Im not going to use the dump valve because im using 18 sprayers so the system loses pressure quickly after the pump is off

so you're filling the trash cans with concentrate and the dosatrons mix it with your tap? are you ph'ing the concentrate? are the dosatrons on separate water lines? which dry salt ferts have you been having success with? i have used jacks pro hydro/cal nit/epsom and also maxibloom in dwc. im...

good to see ya back in action

thanks for sharing heartlandhank. so are you getting equal water distribution to each site? what exact pump are you using. i'll post some pics up soon, once i get my girls transplanted. they are all still in half gallon nursery pots being hand watered. couple things. the fittings for the poly...

i just looked through your thread again and noticed i have different fittings for tapping into the 3/4 inch line than what you used. i didn't get the pressure compensating valves. this may or may not have anything to do with my leakage but i'm ordering some none the less.

i got everything put together yesterday but have an issue with the fittings leaking. i connected 8 sprayers just to test it out and it works pretty slick but 6 of the 8 fittings are leaking. what was your technique for attaching the fittings? you were using 3/4 inch rigid black poly line right?

awesome contribution thank you

try switching to lucas and see how it works for you. what is your humidity at in your room. low humidity will cause plants to drink up water as opposed to eating up the nutrients. try to keep relative humidity above 55% google vpd(vapor pressure differential) it will show you a chart of where...

here are a couple ukem x grape ape in rdwc for something to look at.(18 days in flwr)

I threw together a test system tonight. It worked ok but needs a little refinement...

the first system im building is 100% mack's design,the only difference is i'm going to use a pump with a little more flow and stakes with a little more gph in hopes of reducing feed time. i'm using a smaller solenoid as well(cheaper). i used to post in the dwc section mostly but it seems dead...
