No problem. Now you see the scam- flushing solution is just sugar water! Total rip off!
Thanks for the share - good looking source ;-}small amt.'s of raw ingredients here

Yessir. Clearex is nothing but weak sugar water. I like to use a little molasses for flush.
So it seems this person in the article seems to think that "Clearex" is more than just sugar water. Also, the proportions used when compared to the solution of MgSO4 and glucose @2g/gal are very different. He uses table salt, baking soda and glucose to replicate the "Clearex". Interesting stuff. I wish I had enough room to do a side by side.
My own recipe for 'Clearex' is 2 dry grams per gallon each of both table sugar and Epsom salt. Dissolve in a little hot water before I drop it in the res, works like a champ and I'm not changing... especially for the money. 80 grams of each is what I use for a typical res. change, that's pennies!
Final step is to pH the system to about 6.0... and the ladies will be ready in as little as 4 days. I don't do any of the crazy heavy feeds of this or that, so typically there isn't an excess of nutes to flush from the plants anyway.
I thought about changing up my nutrient regimen until night before last, when I harvested colas thicker than my thigh. So I'd say it's not my nutrient regimen that's holding me back here! LOL
Right on man. Was just pointing out the differences to see if anyone could chime in. Also, I believe that link to either be Spurr's website or a disciple of his. I have never been able to get into it, but Spurr is the one who created the Hydrobuddy program, if I am not mistaken. I haven't looked at it much, but it looks powerful in the right hands. Also, just to be fair, Spurr's (I think it's his) flushing formula (clearex alternative) looks like it would be cheap as hell also. I was mainly interested in why you use Magnesium Sulfate as opposed to Sodium Bicarbonate and Salt. Just curious is all. I'm no scientist so I have to rely on the more educated. Thanks for the reply.
So I'm still kind of lost as to why table salt and baking soda are used in this "Flush" by Spurr, or am I just totally misinterpreting this? Sorry if this is off topic.
I'm sooooo not flushing with hydrochloric acid! Wtf? I think we need to get Squiggly in here to explain to us mortals what is going on here.
You can, it just needs to be dilute enough.
As the article says it's all about cation (positively charged ion) exchange.
Acids provide protons (the most basic positive ion H+) and these can help to displace other cations we're trying to get rid of.
Also as the article says, you can use a basic solution and achieve the same effect. Instead of focusing on displacement this relies more on positive-negative (polar) interactions.
End of the day the true explanation for all of this is fairly advanced and has a lot to do with thermodynamics/kinetics. Heady stuff.
So really look at it this way (like the article says). You can flush through with an acid or a base to try and get rid of some of the salt buildup (if it was me I'd hit it with an acid solution first, then hit it with a basic one next time to cover all bases)--and then run RO water through.
To be clear, don't run an acid solution followed by a basic one. This could produce salt and cause an acid/base neutralization in your medium. Flush with plain water between these treatments if you choose to use both.
Your plants can handle very dilute HCl--just don't treat them with it without following up with some RO.
Has anyone been adding any fulvic acid to their dry salt regimens? I see customhydronutrients has it in bulk, as well, and I'm used to running a little GH Diamond Nectar. Can't go wrong with chelation, right?
So a quick look at customhydronutrients tells me they sell products with low prices. Are they worth it? They also have a nice little write up on their 1 LB. soluble fulvic.
