</troll> Throw some food coloring in your water and grow some purps. </end>

As far as your septic capacity it's a lot of work but you could always cut the top and bottom off a 55 gallon drum and dig a hole outside a few feet from your foundation and the put the drum in it and fill with pea gravel. Just have to pump the water to it underground also a bit or your lawn...

Yeah you have a lot of bicarbonate so you're going to use a crap lot of acid. The sulfuric acid is probably fine for dirt(buffers nutes) and fine for older plants but just remember that if you're starting seedlings... 30% sulfuric acid = 30g/100mL = 30000mg/100mL = 30000ppm/100mL Now if you...

If I plant strawberries and end up with a pound I'll be upset. it may be good for what you grow but isn't much in terms of food. I just want a system that will grow some decent food without making my house smell like dirt. The whole bubble stuff etc etc sounds complicated and I already have...

First off, I don't grow the same plants as you so some of the same issues may not apply. I was thinking of a 1 foot deep box lined with poly. The top would have 2" net pots ever square foot for versatility in placement. 1/2" pvc and backyard misters would be positioned to shoot at 70psi...

Yeah it depends on the water and you should get it tested. Just to give you an idea.... If you have a lot of bicarbonate in the water it may take you as much as 2mL of some 36% concentrated acid to lower pH of a gallon. Not such a big deal with soil as it has a buffering capacity and runs...

Except again i believe magnesium nitrate is kinda expensive. You can make it with .....nitric acid lol. And magnesium but again nitric is expensive and magnesium reacts violently with water.

Yeah nitric acid is some strong stuff. If you're going to make your own nitric acid there are two ways and both give off toxic fumes that can seriously maim or even kill you..I don't think a mask will protect you from the fumes so you need to have enough ventilation that they're all completely...

The $100 price tag comes from Ebay as I looked at nitric acid before when I entertained the idea of using it to make magnesium nitrate. I've never really looked at pH up or down products sold specifically for your plant but from what I've seen in these forums previously I always assumed they...

Nitric acid will work, but I don't grow the same plants you do so $100 for a bottle of the stuff is a little excessive lol.

Uncle Ben isn't an idiot, at least not in recommending spinout, it's approved by the FDA, it's now called microkote though. They sell pots already coated online or you can buy it as a paint and do your own. Or you can buy copper hydroxide on eBay and buy the food safe paint beekeepers use...

I'd be worried about the aluminum and arsenic. Just buy it in powder form and make your own stock solution.

Yup, all correct. You could use sulfuric acid (sold at auto stores), or phosphoric acid (sold as a powder to create your own concentrate) as well and account for them the same way.

OK, so here's the deal with hard water. It generally has a bunch of bicarbonate that needs to countered with acid. So what are your economical choices? Hydrochloric acid Now correct me if I'm wrong but this is probably a bad choice. Chlorine is known to burn plant tips I've heard in...

After some more research a smart pot system or a tray with a smart valve mk3 or mk2 or aqua valve would work

Is it feasible to build a box lined with poly and set up a float valve connected to an external res that will gravity feed to maintain a few inches of nutrient solution for a bunch of pots filled with vermiculite and perlite or will the constant unaerated reservoir cause root rot?

What was your experience with that?

While I'm asking about this strain specifically I'm also asking generally for your thoughts on the way the marketing, hype, and in turn end product interelate. How do you guys feel about this strain? It's listed as the most popular strain on the breeder's website and also from attitude...

God's speaking? He said get a clue. For whoever shall challenge the ideas of his own religion against those of the other and shall try to disprove those fake religions shall come to find that by the same measuring stick may all faiths fall short. Be it Canaan, Meditha, Aisha or the alter...

I bought some of this stuff for my cherry blossom trees as I don't grow the stuff you guys do but I thought I'd report that fresh out of the bag I'm getting a pH of 4.5-5 between the different pots. This is as measured with a soil pH meter. This is also after watering with water of pH 8 and...
