The right NPK fertilizer for float trays

[bonehead]

Where do you order your supplies? Do you have a link?

i order the nutrients from who ever has the best price with shipping figured in to the total. i use the three part general hydroponics flora series to grow peppers, tomatoes and cucumbers from start to finish and start tobacco on one of my ebb and flow tables with the same nutrients at a reduced mixture. when i change the nutrient resevores i have fertilizer for all the plants in my garden.

Here is a nice article about fertilizer and float trays for tobacco.

hi can you guys share some brands? I'm having difficulty finding the 20-10-20 urea free fertilizer here.

 

[Jitterbugdude]

I believe the stuff I use is made by "Grow more" and it is marketed for orchids.

Cant find that one in EU only by ebay and from the USA, the fertilizer costs 7$ and the shipment costs are 47$ plus customs

 

[Jitterbugdude]

Try looking for Orchid Fertilizer

I may have found a 10-10-20 urea free in Spain, just contacted them.

back, I will need some help, fertilizers can use 3 types of Nitrogen right?
nitric, ammoniacal, and urea, we should only avoid urea?
nitric, ammoniacal N are ok right?

That's right.

Use a TDS merer, $7 from ebay, use a non urea based feed and have it up between 220 and 300 and all will be good, at that range you will not be at optimism but depending on the feed you will be safe. You could go double to triple of the feed so right and water quality is taken into account. I am quoting ppm of nitrogen over water hardness if that makes sense.

Hi again and thank you all, it as been an hard work to find the fertilizer here, I've called lots of factories, commercials , engineers etc, by now I may had found a 15-10-15 urea free but I will have to wait until Monday because the commercial will need to locate a place where I can buy it.

My water analyses are these

Ph 5,7
SiO[SUB]2[/SUB] 13.1+0.4mg/L
Dry residue 41.1mg/L
Dissolved mineral salts 47mg/L
CL 9.3mg/L
HCO[SUB]3[/SUB] 11.0mg/L
SO[SUB]4[/SUB][SUP]2- [/SUP]1.43 mg/L
NO[SUB]3[/SUB][SUP]− [/SUP]1.62 mg/L
F− <0.08
Na 6.9 mg/L
Mg 1.63 mg/L
Ca 0.7 mg/L
K 0.84 mg/L

If you have oriental tobacco, you can use 7-7-7 or 7-14-21. you know oriental tobaccos are don't want N.

Is this an analysis of a mineral water ? Although other levels are not looking bad Cl level is high. Actually, I don't know if your analysis is giving the "free chlorine" level but this level may cause combustibility problems on your leaves. if I recall correctly, Cl level of a standart swimming pool is max 1.5 mg/l and optimum is around 0.5 mg/l. (for a comparison)

 

[forumdotabaco]

yes mineral water, I started with distilled water, and I changed to mineral a few days ago.

 

[forumdotabaco]

anions
chloride CL 9.3 mg/L
Let the water breed for a few days may solve that right?

Yes, you can leave the water out and the chlorine will leach out.

You may also have success with captured rain water.

 

[forumdotabaco]

I was buying mineral water to avoid chloride, looks like I will have to read better before buy it.

 

[Matty]

Maybe it would be a good idea to find out how much chloride is naturally present in any water. I checked some pages using google and saw a lot of high chloride levels, one was 25mg/l for tap water.
