Dutch Master Reverse-Does it work to prevent seeds?

[SooperSmurph]

my guess is that the reverse that you had was past its shelf life and/or improperly stored
from your posts you said that you used a surfactant as DM recommends so that narrows it down to a bad bottle or batch
its very doubtful that strain makes any difference that would be like saying that because you are not caucasian these birth control pills wont work for you

FWIW DM saturator is a excellent surfactant for all of your non-ionic follar sprays

Wasn't saying that strain had a particular problem with the product, was suggesting that lines which are thoroughly hermaphrodized will produce male flowers because they are genetically predisposed to it, the same way male flowers would form on a male being sprayed with reverse.

Reverse is ready to use, just add the proper amount of Penetrator and thoroughly cover your leaves and flowers. Use as a preventative before bloom
set and as a reactive after flowers have begun to form. This type of product is responsible for the marketed “seedless” varieties of cucumbers,
watermelons, and other curcubitz.

Its probably the commercial fruit setting agent Epheron/Florel repackaged at ten times the price , they will not reveal and the MSDS lists nothing usefull.

ok now i understand your beef with reverse,i never thought that you wanted it to prevent male flowers
usually folks buy reverse just to keep seeds from forming and that's it not to prevent or reverse hermies
Im not aware of any off the shelf products that will stop or reverse hermi traits,wish i did it would be a lifesaver for some strains

 

[SooperSmurph]

It didn't prevent seeds either, in my case, it was presented to me as a preventative for both bananas and seeds.

Just a quick update on my experience so far.

My flower rooms (2) are 6x7x7 and lit by 3 (bare) 600 hps (dimmable) stacked in the center. Plants grow up the walls. The room with the "nanner throwing bitches" is approx 3/4 full.

I aquired the product on 5/1 and hit them with 1/2 a qt (5ml saturator added) about an hour before lights off. Dimmed the lights to 300 watts ea for 24 hours. No noticable burning of the plants was noted.

Since the directions on the bottle also state to use the product "as needed", I hit them with another 1/2 qt on the 3rd, and then again on the 6th. I plan to hit them yet again on the 10th.

When checking them today, I noticed a few swelled seed pods that I hadn't noticed before. I picked a couple off and the seed inside was much "mushier" than expected. About the consistancy of a fresh cuccumber seed. Have not noticed any new nanners.

Can't say for sure yet if this stuff is snake oil or not. Just wanted to give those interested an update.

Removed from where?

From the manufacturing line. The link you post is either old stock or they simply haven't removed it from their website.


Dutch Master Reverse has in fact been discontinued it appears.

I'm not sure. If it has been discontinued, you would think that the manufacture's website would show such? It does appear that they've added "gold range" to the name.

Guy at the hydrostore says he can no longer get it in 1 gal bottles and had none (1 gal) on the shelf. I bought 4 1 liter bottles (all they had).

I guess we'll see...

well I used it for a while and I can say if most definitely worked for me. coincidentally I bought it to try out on my keeper from a pack of double strawberry diesel, leaned very heavily towards the sour diesel and yielded fantastic, only problem was it hermed everytime, not real bad but still. I inspected every inch of my flowering area and finally figured out it was just the genes. every grow at around 5 weeks of 12/12 it'd throw some balls. I bought some reverse and started using it during week 2 of 12/12 and again at week 4, never used the penetrator though. anyway after I started using it it never hemed on me again. I lost that cut while I was shutdown last year and I want it back!!!! maybe it only works on some strains but I know for sure it worked for me

 

[RM - aquagrower]

That's geat to hear. The lady in question is in fact from a pack of Rez's double strawberry diesel (2006-7?), as is exactly as you describe. Luckily I have 2 keepers from that pack. 1 that's pretty close, and this nanner throwing bitch.

Have 5 that went into flower 3/24 and are showing seed. Another went in 4/8 and hopefully this stuff works. Just culled 9 of these from the veg room cause I'm gonna pull it from the rotation. Kept 2 small clones in pre-veg for later.

Once again, we shall see...

Those who still list it online are retailers. Perhaps they still have some available, or perhaps they havn't updated their website.


The major distributors (at least who supply USA hydroponic shops) are no longer listing it on their websites. It has been removed sometime recently.

Hydrofarm.com
BWGS.com
SunlightSupply.com


^If these major wholesalers no longer show it (while continuing to offer dutch master products), we can be pretty sure it has been discontinued, or at at the least having some type of issues preventing it from being sold.




Just what I've gathered after seeing my locals stores run out of it and no longer able to get.

Maybe it is just a labeling/EPA issue and will return under a new guise.

 

[RM - aquagrower]

Well FF, ya just might be right about it being discontinued.

http://www.ebay.com/itm/Dutch-Maste...829?pt=LH_DefaultDomain_0&hash=item2ec4006ce5

For those that don't click outside links, 1 liter for $1123.95 (only available at "buy it now"). You've got to be kidding me.

 

[RM - aquagrower]

And just to back that up, a couple days ago, someone paid $125 for 1 liter

http://www.ebay.com/itm/Dutch-Maste...007?pt=LH_DefaultDomain_0&hash=item35c744845f

I've still got 2 (un-opened) 1 liter bottles on the shelf. Hmmmm.....

Has anyone found an analysis of this product ?

After an hour googling i can find nothing but guesses on many forums , and no tests on canna.

If it is ethrel then its 20 dollars a litre from turf and agrochem suppliers as Florel and similar , or as powder from scientific sources to experiment with.

This short pdf sums up is chemistry and mode , wide variety of uses.

 

[RM - aquagrower]

Found this elsewhere:

"Pulled due to inhalational and oral toxicity as well as developmental toxicity to offspring. Animal and tissues studies have been conducted and the substances like palcobutrazadol and Daminozide (particularly oncogenic, tumors formed in all test species at varying exposure levels). None of the uses of these products includes consumption, presumably Dm couldn't convince the EPA they were selling for ornamental use."

 

[SooperSmurph]

Reverse had Paclo in it?

Is there any non-organic nutrient company that isn't hiding pgrs?

 

[foomar]

Pulled due to inhalational and oral toxicity ect

It references a pdf on stopping paclo use in amenity horticulture , but no evidence to support its presence in reverse , possibly just more speculation without a proper lab analysis.

These PGR,s were marketed by pushy agrochem reps to the grounds maintenance industry here many years ago , promiseing saveings on costs for hedgecutting , needing just one cut per year instead of several.

Worked fine for four seasons , then a massive die back on certain species from cummulative effect led to its disuse long before health and safety concerns were raised.


Looks like ethrel would be a safe alternative , widely used on food crops for decades , its effect on curcubits is just what we need on bicurious canna.

Next time i get a hermie i will try it.

 

[LyryC]

I was going to use reverse for the onset of flowering.

I think i'll just stick to searching the plants and castration.

100% off the shelves - I can barely find it anywhere except one of the links above/ebay.

hope RM-Aqua had good results and all is well.

Stuff worked as advertised for me. Shame it ain't available anymore.

 

[944s2]

no ban in the uk as i have 3 ltr coming soon,,used it for years,,always grow with fem beans [except my lasting run] and multi strains always in my garden,never no beans,,must never use after the recommended time limit,,never dilute and use with penetrator,it will go further,,just saying i have found it over the years,,,
i first starting using it when it was named feminizer before superbud got banned that 1st time, ten or elevan yrs ago give or take,,others think its snake oil,,cheers 944s2

Hey smurf

Hey smurf

Used it initially at my new warehouse, the old grower swore up and down that it worked, yet I combed through his plants and found many that were simply rife with bananas, the room in which these bananas formed produced mature seeds, despite the continued use of reverse, so I experienced neither of the results you claim Reverse is capable of.

Admittedly, the examples producing Bananas were Blue Satellite, a cut that is notorious for hermaphroditic tendencies, but the seeds they produced remained and grew to maturity in all the other strains present, so the things you say Reverse does, it didn't do for me, or for anyone else locally according to retailers, I offered my last full bottle of reverse to anyone who wanted it, here, craigslist, and at Grow stores, I even included penetrator, no takers.

For $70 / gallon you figure people would be scrambling to get a hold of it?

wow those post about the toxins in them turns me off was interested in scoring some to try out not sure if I want to now just can't believe people are selling this shit on eBay for like 50 bucks buy it now if it's no good. Was looking into getting it to try out because this strain I have lime cookies is supposed to have some issues with hermie plants popping up maybe it's because they are S1's or maybe just because something in that cross I don't know. Well still wouldn't mind trying it so smurph if u wanna off it I'll pay for the shipping cost and everything. Lol mike
