As you know, Nutricote and Dynamite are the same thing. Nutricote's been used for a few decades by the large agricultural interests. Except: Florikan figured that by re-branding it, they could get folks to pay $7-8 for 2lbs instead of $52 for 80lbs - and you don't have to have minimum order quantities of 5-6 bags just to get them to deliver. Not everyone's got an orchard...the new marketing seems to be working, too.

Influence of Temperature and Time on Nutrient Release Patterns of Osmocote Plus™, Nutricote™, and Polyon™ Controlled-Release Fertilizers (PDF)

Two experiments:
1) CRF's suspended in water at 40C (104F) for several weeks; and
2) Impact of Columnar Leaching in short-term diurnal temperature fluctuations (i.e. 'night' and 'day')
You're gonna want to read that one for yourselves, guys. It pertains to YOU! (Yes, I'm makin' ya do some work...)

OSMOCOTE Notes:
Sounds consistent with what
Irish was seeing. Water 'em and they perk back up - water more often (but less each time instead of 'binge drinking'), and they seem happier.
I'm sure the same rules re:
concentration apply here as they do with a hydro res: go from a 6 gal full res down to ~1-2 gal, and you'll start seeing toxicity/salt issues. Looks like ya
need to keep the medium moist -
especially if you're applying all the CRF to the pots at the start of the season.

Orchids are a bit finicky sometimes, too; to wit, these folks say within:
The Orchid Fertilizer Bible:
Smaller meals instead of one big one, huh? Works for me. Takes away a bit from the 'just add water' simplicity, but if it's for a good cause - might be worth doing a
little bit o' actual work to grow these plants, eh?

Some comments from users of
OC/DC (warmer climate users, mostly) over on
Gardensweb; can't link to them directly from here of course:
------
Lowe's carries it in their stores, but previously did not list it on their website; now they do:
Lowe's Garden Club Select (4 Formulations)
----
More info about greater release of OC ferts in high temps, esp. Nitrogen:
Release of nitrogen from two controlled release fertilizers (Osmocote Plus and Osmocote Exact)
That seems to reiterate/reinforce some of the above comments from people here.

Now, all that really tells me at this time is that if you're:
1) Growing in a Controlled, Conditioned (HVAC) Environment (i.e. Living Spaces):
* You have a wider range of options with regards to which CRFs/TRFs to use, when (how often), and at what time of the year (temperature/seasonal)
2) If you're Growing in an Unconditioned Area (Non-Living Spaces) (crawlspace, garages, unfinished basements, attics, sheds, etc.):
* You want to take into account overall plant growth factors (Q-10, etc.) as well as nutrient release factors -
which you should be doing anyway.
Same applies whether you're using LEDs vs HIDs, and all the rest. Don't blame the preparation (or lack of) or necessity for using a particular growspace for the results you get. Everyone works within their own budget, security concerns, and living arrangements.
We all make do with what we've got.
And,
good information backed by personal experience is the
best foundation from which to make
any decision.

I've usually had the luxury of growing in conditioned air spaces myself when indoors, so I'd leave my options open if using CRFs in the future.
Plenty of folks (esp. in temperate climates) over the years have been using various formulations of OC in their gardens with great results.
Got kids, or antsy spouses, or nosy neighbors/landlords and draconian state laws?...then you also have fewer options, and your considerations will have to change accordingly.
Everyone's goal
should be to grow in as conditioned and controllable a space as we possibly can (
indoors, that is -
legislatively, we want to do away with the necessity, of course) - if you have one, than kudos to you! Hard work, knowledge - and a little capital expenditure - will always pay off for you in the end.

In the meantime, let's not have bias for or against anyone here either for/from their access to - or lack of - resources in setting up their garden space.
...
Garden envy, anyone?
Especially if they're buds of mine.
Be nice...or I just might have to
Open Up a Can o' Whoop Ass on ya--!
