Hydroponics

I've always grown in soil but I am finally giving hydroponics a go. I have 2 tents, a 2'x4' and a 4'x6'. I bought a flood tray for each but still don't have a definitive plan. Do many people run 2 or more tents off one reservoir? I'd love to keep my reservoir outside the tents where I have easy access and the ability to feed both tents from it. I'd also probably need pumps to push the water both ways (in and out of each tray). I haven't seen any grows yet of people doing this although I've only browsed a bit on youtube and seen a few flood and drain setups on RIU.

So can I do this? Any links to setups like this? Or just tell me it's a bad idea... :)

All right! Hydroponics is what I know, and hydroponics is the way I grow! :bigjoint:

This forum will be great, we can discuss anything hydro. No dirtbags here, We haul water!

We can compare the different nutrient salts, and all of the additives. Plus the kinds of soilless media and what irrigation system is best for each. And of course, pH and TDS measuring equipment, feeding and flushing, etc.

And all the while, we'll make fun of those guys hauling big bags of dirt! :blsmoke:


I can't think of any questions right now, what do YOU want to know?

looks like just a one part? Easy enough, youll need a ppm meter.Mix half of what the bag says.Check ppm.Small seedlings dont need much 1-200 as they grow increase to around 5-600 ppm.

1/2 would be 500 gals don't have a tank large enough I divided 130 Oz into 1000 gals
That gives me 7.69 Oz per gal x that by 112 gals = 861.28 over half of fert. Thankd

I called the number hotrodharley posted, turns out there are 2 Peter's fertilizer companies but all is Good! Kaitlyn from Jack's ( Peter's) ran dulition turns out I had a senior moment my number was correct I just didn't move decimal point over big Da, Thanks to all who posted now I hope I can find the greenhouse

Whats a general flush time before harvest in DWC? the last 2 grows i did in DWC i flushed for 5 days, then 14 days with little to no color change in the leaves. Thats without and flushing nutrient like flora kleen, just water.

Personal preference for most and seems like you have two data points to judge from....was there a difference between the two? I personally flush the res with flora Kleen then refill with fresh PH RO H2O for 2-3 days then chop. I have found that is the peak line for Benefits gained for my process.

I have not tried with the flora kleen yet, just found it weird that after 2 weeks i showed almost no change, like i was still running nutes. In return i got buds that were really clean tasting and just not good, so i bought the kleen. Will be giving it a shot on this next harvest i got coming

Yes because once the plant absorbs the nutrients you cant flush them out.Ive never tried but I wonder how long you could go with straight water before a deficiency.Never the less feed low and you wont need to.

Hello everyone! Just checking in with my fellow hydro growers. I am a medical patient growing my own in a 2X4 tent using 8 gallon containers. I am about to harvest my second grow and have 3 Kush XL autoflowers waiting in a 2X4 shorty in another room for the tent to be vacated. Soon I will start some Skywalker OG photoperiod ladies and search for a good mother to clone.
I will be lurking and learning as much as I can. Nice to meet you all ;)

You can its called cannibalizing. For instance if you put no nitrogen in your reservoir, your plant will literally eat the nitrogen out of the leaves turning them yellow. Things like nitrogen are called "mobile nutrients" because they can move to where they are needed. Plants will automatically "flush" themselves at the end of their lives, but your like 70% amber at that point which is why most growers force it by starving the reservoir. When your pant depletes all of its phosphorus all of the leaves will start to turn a purple color.

do not flush
it starve the plant and kill the final product

feed the right EC all the grow until the end
the overall color of your plants will tell you if you are in the right spot

ph/ec flucutuations in the res too

they must be green until the end .. never yellow
if you get bad taste/black ash it means you overfeed/had nutrient accumulations

I don't flush.
I can't flush.
The water runs through my fish tank.
So I just watch the PH. If I time it right I could let the nutes fall off near the end, say 2 weeks out. But things like phosphorous don't budge much. Potassium seems to stay up. Calcium will drop off and nitrates also.

So I am running a RDWC system and found my pH runs a tad on the lower side. I just checked mine today after adding 5 gallons to a low reservoir last night and it was at 5.83. What is a simple way to raise it slightly because I have gotten some brown/yellow spots on the leave this past week. I read in the group that you can use drain cleaner? Is this true? What is the safest and easiest way to accomplish what I need? Thanks. I also use liquid Fox Farm for my nutes.
