DWC setup help

[Kronz]

ill be back in 10 and let you know. You think I should just drain some out and add just plain R/O water?

Kronz Reviewed by Kronz on 10-25-2009. DWC setup help Just went and purchased two 14 gallon containers to start a dwc. This will be my first time growing hydro. I have been reading threads of how many plants i should put in each container but everyone has a different numbers.. I am going to use a 600watt hps system. I was thinking of 3 plants in each container, so 6 in all. how many plants can I fit under a 600hps? I am going to setup it up tomrrow and will add some pictures. But any help would be great.

i would drain as much out of the system as possible,just to be on the safe side. A general guideline for TDS levels : seedlings = 50-150 ppm; unrooted clones = 100-350 ppm; small plants = 400-800 ppm; large plants = 900-1800 ppm; last week of flowering = taper off to plain water. remember u need to subtract the ppm's of your tap water from your nutrients.if your bottle ses 600 and u have 200 to start with.your overal number is now 800 ppm and not the 600 most people think is there.

my PPM without any nutrients is 8

okay just did a semi water change. My PPM is at 224 now and my PH is at 6.14

Im going to wait for about a half hour or so and check on it to see where the PPM and PH is at.

your lucky thats the lowest ppm num i have ever seen. based on your plants age,use the scale of ppm numbers i posted for you.auctually copy and paste that to your computer it will save u tons of trouble in the future i promise.with your system full of water and calmag only,start adding small amounts of nutes.test your water.then in 2 hours go back and check again.because u are doing a recir system u need 2 give it time to even out.after 2 hours check again if your numbers are low add a little more nutrients.basically it just takes time even your system out and mix every thing up..for the next 24 hours go in and randomly test your water through out your day/night.numbers change and especially right now u need to be on top of it. i would try and stick to the lighter side of nutrients for the first little bit.all of the plants have stress from transoprt and setting up a new home"it happends to every one" and then start upping your solution.as a personal note i do need to say that bubba is a light feeder during veg.so keep it simple and try and find a good number that both strains like.

PPM at 780
PH at 5.4

Bought a couple waterfarm buckets yesterday. Going to use them next time around. Got another nice size clone and replaced it with the one that was dying.
