My website doesn't sell anything right now? So, do you mean some of the sites that I linked to? Or others linked to on this thread?

I just got back quotes for the last of the stainless parts I need to make 35+ gallon containers. If I were to offer these for sale, I can be price competitive with current culture on their big 35gal UC Pro buckets and do it using stainless steel.

You are 100% correct here. Sometimes I should reconsult my chemistry books instead of insisting I remember everything all the time. I've fixed things to account for this.

This is a short tutorial on the physical steps it takes to mix your own nutrient stock solutions. It's awfully simple, sure, but I figured it's worth posting. I know many of you that might be on the fence will realize it's just as easy as baking or cooking. So now you've decided you want to...

Believe it or not, it won't have a very sophisticated control system. Maybe pH control at most. Water quality analysis can't be done in real time very well, at least, when testing for most macro/micro nutrients. So, I send them off to a lab to get done and I adjust my fertilizers based on the...

Would you switch to something that was identical to FF buy 1/4 of the cost?

My brand? My own. :D Brand loyalty costs everyone money that they don't need to spend.

Sorry, it was a link in the first paragraph. http://www.open-salt.com

I've seen it. He said it would cost over $500 per site for a finished system. I'm down around $200-250/site for a finish system at this size. I don't remember what size his tanks were. But the waterfall he creates in every container is what makes it so expensive. I have some larger containers...

They never go bad in the same way as food. Water might evaporate a little so you might want to add a small amount of water. Definitely shake it really good. Heating on the stove to 140-150°F is a good idea as well as it can help redissolve the compounds that might have precipitated out and...

It is illegal, AFAIK, for a city water source to be above 500ppm TDS.

Why is this thread in this sub? OP must lack some common sense because this has nothing to do with business discussion.

I didn't drill holes in anything. The shop that made them does all that. I think the pictures just don't show any of the holes.

You are right. I could probably buy 100 of those 5 gallon buckets.

A thin plastic container can also be broken during a move or due to some accident or whatever.

Never having to replace these again for the next 30 years? Definitely not a waste of money.

Wanted to show you guys my latest project. I'm building a stainless steel RDWC system. Because outdoor/greenhouse RDWC and I wanted it to last forever. Being a mechanical engineer has its perks. Everything you see here is 304SS. I ordered it too thick at 16ga, so the next ones will be 20ga, but...

Botany is general study of plants. Horticultural Science is the study of growing plants. You'll probably be able to apply more from Botany at plant genetics, but horticultural science is ultimately more useful.

Botany or Horticultural Science.
