Question for the water gurus

[Daves_not_here]

So I am planning to do my first greenhouse grow this season on a new property. I had the water checked and these were the results. Does this look ok or is this water no good?

Looks really clean to me. The red lines are warnings you need more. Only Iron looks a bit excessive, but what medium are you growing in?

Where did you get these test results from? Did you go through something like logan labs?

 

[Creeperpark]

The TDS is only 44 ppm your water should be ok. Are you pumping from the ground or importing through pipes?

Growing straight in the ground. Here is how my dirt tested

I used a company called waypoint analytical they are local to me.

Will be pumping into a 3500 gallon res that is on a 8 foot high platform. Will pipe from there to 250 gallon totes at the greenhouse.

Hmm look at that iron and manganese again. That's where the water has picked them up.

I would look up the acceptable levels for soil, as it looks quite high. If rain is peculating through that, then being put back in as irrigation water, it will increase over time. The water about has enough for hydro needs as it comes.

Lucky you friend. If I had water with a starting ppm of 40 I would call that kick-ass water for the greenhouse. It will work fine however you will need to have it rechecked when the season changes and it gets dry.

Iron and manganese can be buffered very easily when the starting TDS is 40. I'm talking about total dissolved salts in the water. Iron is not a salt or manganese either. They are both minerals.

What type of substrate are you using, if you don't mind me asking?

He is going in the ground.
My comment about checking f-e levels was regarding his soil report. 200ppm is way higher than the few ppm a plant actually needs.
I have a bit more time now. 200 PPM is indeed excessive, but at this level it's manganese uptake that's usually effected. As luck would have it, the manganese levels are also high.

I would run with it. If you have a huge investment then trailing cheap filtration would be worthwhile. Then over time the levels in the soil will drop if no more is added. Which I wouldn't want to do. Any feed choice needs to have it's iron looked at, and professionally, I would formulate something with non at all. Long term goals are reducing it.

So I am planning to do my first greenhouse grow this season on a new property.

You could bottle it and sell it.

Just call it "Dave's Not Here Creek".

Thanks for the input and help guys. I’m attaching some pics to show exactly what’s going on at my new spot. in this pic the black dot is where the greenhouses will be going and the small blue line is the natural spring creek And yes I know it looks like a huge dick and balls lol .

in these pics

it shows the field where the houses will be erected.

and here is where the spring starts to fill the creek. The hole where it comes out and starts down the creek is roughly 12-14 feet deep. I have been on this property for almost 30 years and have never seen this creek dry up.

and lastly here is the beginning of hoop house number 1 going up. I plan on having 7 houses that are 20x96 and an extra house that is 20x96 for mothers and propagation.

Interesting play on words.

I look at all the work being done, and think back to the early 90's, getting $240 an ounce for quality bud.

I hope you have a good hook-up so you can get quality prices.

If I see one of my old friends from the 90's, the price is still $60 a quarter.

Decided instead of buying lumber for my band boards I’d break out the ole mill

You say 30 years and have never seen this creek dry up. With that many greenhouses that creek may not be able to sustain enough water. I would add a large water holding tank for extra water storage during the rainy seasons to use when it's dry,.

A rule of thumb is to have available 0.3 to 0.4 gallons per square foot of growing area per day as a peak-use rate for the warmest day. For example a 30-by-100-foot greenhouse with 2,400 square feet of bench area would require a peak-use rate of 720-960 gallons per day. Google

Those are good guidelines.

When we have another few weeks of extreme hot weather this summer, it's good to have extra water to cool down plants that are above ground in big pots.

Just stick your hand in the soil when the sun is blazing on it. That is not what you want your roots to feel.

I had thought about this and didn’t know the exact math needed to calculate what would be needed. I have acquired 4 of the 3500 gallon holding tanks that I plan to raise on platforms to work as makeshift water towers. From that platform I will have piping to 2 of the 250 gallon ibc totes at each house to water out of. I might need to add a third tote at each house now that I read your comment.


also day one is in the books.
