not to sidetrack but jig... how long does the DM lineup last you.. i have seen your results before and im switching overt to rdwc. if i ran a 20 bucket system w. 2 55g drums for rez. how fast u think id go thru the lineup??? were talking roughly 100-120 gallons.??? im gonna shoot to do a rez change every 2-4 weeks. would that be sufficient? in your opinion... and anyone elses opinion is WELCOMED as well!!!!
You know you are liked when I'm willing to go through all the work to come up with these numbers.
Glad you are back SFguy.
So, I picked a random website that had all the DM gear on it for pricing. They seems a little higher than other places, but had a good selection. You could probably knock a dollar or two off if you search. But this gives a baseline. DM has a few different base nutrient lines. They have the Advance (old stuff), Gold (new stuff) and One which is all in one, no A+B. I leave out the One, and chose Advance because it's cheaper and what I use most of the time. I suggest using at least their Silica and Zone. They have a potasium booster for flower I like to use... and another product called Add 2.7... seems like snake oil to me... but I've used it and liked the results. Never done a side by side... so really not sure if it's worth the extra money. Probably not.
I did the math for a 10 gallon rez, for 8 weeks of flower. Changing the rez once per week. The 2 prices reflect using 1L bottles of the additives vs 5L bottles. Using the 5L is cheaper.
Using DM Advance Flower A+B, Silica, and Zone = $18 or $16
Adding Potash+ = $24 or $18
Adding Add 2.7 along with Potash+ = $45 or $35
You can save quite a bit buying in bulk... and that Add 2.7 really bumps up the price per crop. I use the $24 line up with the 1L bottles.
If you want to run a 100 gallon... multiply everything by 10. Anything from $160 - $350. (as you would be using the 5L and not spending the extra on 1L)
Hope that helps.
