advanced techniques|experimental methods|tests|plant physiology+manipulation|env eng

dedicated thread
advanced techniques, experimental methods, tests...
plant physiology+manipulation, environmental engineering

goal
collect & share various advanced, & experimental techniques from around the world of gardening.

*propose & proceed w/ tests re the viability of fertilizers (organic, chemical, foodstuffs, &/or other materials)
*lighting/photoperiod manipulation
*temperature (root, canopy, environment @ large, day/night (diff) *watering frequency, amount, quality, recycling, etc.
*foilar feeding
*additives
*supplements
*catalysts
*flowering boosters
*vegetative boosters
*mechanical, electrical, hvac, environmental engineering & greenhouse engineering in indoor gardens
*advanced math, conversions & formulas

**et al, etc...

rule
every garden/er is distinct, different & respected.

not a debate thread.
not lifestyle thread.
not social networking thread...

just raw scientific facts...reference materials, white papers, wild experiments, collective tests, plant physiology & manipulation repository.

thread is not for new gardeners seeking basic knowledge... unless new gardeners are experimental & dont seek to run these experiments as standard gardens.

thread is for gardeners that are inclined to engineer, run many different medias/systems @ one time, or have run many different types of gardens, & wont snivel if a test/method described kills a plant or two...

thread is not to instruct, teach, persuade or convince - just to share raw data & go to the furthest reaches of indoor gardening...

thats basically it... until/unless other points arise...

advanced techniques...
experimental methods...
tests...

plant physiology & manipulation...
environmental engineering...

for enthusiasts that truly enjoy their gardens...

what about a high pressure grow chamber? it'd obviously have to be a closed system, so you could pump the co2 in there like crazy too...

NASA hypothesized that if Venus had an ecosystem, a tomato grown there would be the size of a pumpkin

should be inclusive to the environemtal engineering portion of the thread...
could have stated controlled environment agriculture, but the environmental umbrella should cover hvac (heating, ventillation air conditioning) & bas (building automated systems) & cleanroom specs...

nasa used to use a biomass production system...

they have used these on the int'l space station & as precursor to space station biological research program plant research unti (pru).

can seal nearly any room to desired specs - if know specs...



laminar air flow... turbulent air flow...

combining both in garden seems to be effective... w/ the laminr going up thru leaves & carrying heat thru vents or into ac grill... turbulent to keep the transpiration rates high & to carry away water given off ny leaves...

https://cleanroomproducts.wordpress.c...assifications/

can diy a decent clean room & set pressure to desired levels...
design & build your own cleanroom:

enjoy your garden!

Thanks for pointing me to this thread.

I think you need a specific section for that. We have done the same on our forum, but a test or review per topic. First we have the announcement of the test (moderator task on our forum, describing the test and what is to be tested, what or who you are looking for). We give all information about the product and ask for suitable testers to come forward. Then we select the grower and he or she executes the test in a topic. If possible we supply the necessary tools or measuring equipment, the supplier supports the product.

We chose for only testing in one section and only accept tests from suppliers who actually support their product in the test, and do it through a designated moderator who initiates and coordinates the test. So it's not a "free test market" - you need to dose it a bit too. Testing that way is a lot of work and a lot of fun. I have seen some pretty impressive tests on this forum too btw that qualify for being in a section like that. We also have lab sections about genetics (Cannalytics profiles, tissue culture etc) and light and lighting equipment. You only need to learn Dutch as we Dutch speak a lot of it .

I would personally strongly support test sections on other fora, and a lot of knowledge transfer between them. That's one of the reasons I published our first test results for the Ballasts as well. Too interesting to keep for yourself

thx for stopping by.

did what could to bring the concept to icmag... maybe no interest here...

your technical skill & test evaluation experience would be nice to have in a forum @ ic...

the centralized lab & double blind testing protocols are nice.

like learning millimhos, ec & par watts?...
just language. will work on it...

would be nice to have a testen nl onderzoeken @ icmag...
the hps-mh vs. hps thread was informative... what was the c*nn*biniod profile difference(s) on the samples, if any?

enjoy your garden!

This should be a subforum sooo many topics could come up the info would be better organized by thread. There are a zillion subsubforums on icmag why not one more.

I haven't received the samples yet, but that will be published of course when the tests are done.

Yes, I think a test section would be nice. We als made a sub-section especially for electrical questions in the Growroom design section, that proved to be very successful. We have been really fighting for growroom safety the last few years.

I do not know if my topic fits into your thread or not, root health, methods, and the outcome - chlorine in tap water is not our enemy, but a good tool to use. LMK if you want more stoner data, and it is OK if it doesn't fit.

Wow this sounds like a great thread! I have a question though, is this thread only for people post their personal experiments, or can we also post peer-reviewed plant science articles?

seems like plant physiology...
are these standard practices, &/or advanced techniques?

should fit into scope of thread... need base of standard, raw scientific data relevant to plant physiology, in order to identify &/or break from that standard in tests...

if there is a general standard for root health & methods to achieve & continue this, can then attempt to manipulate these standards to achieve greater response...

general repository of
1) standard &

2) unconventional methods is welcome...

only request that the data be

1) carefully labeled/denoted/captioned as

a) individual gardeners' own standards/methods

b) methods learned from other gardeners

c) standard textbook methods

d) unconventional textbook methods,

e) etc...


to maintain authentic & reproduceable data/experiments, would be nice to have solid refernce point from the original materials/scientists/gardeners...

also, scientific articles, & excerpts from books, threads, other forums, the internet in general, should balso be referenced...

the exceptions may be trade secrets, anonymity, etc... but generally, data should be cited to the originator...

even if have wild vision in middle of night for experiment, welcome to post here...... just refernce it as your wild concept.

would prefer more actual experiments & advanced techniques & tests, but raw data is the base of knowledge - aside from spontaneous enlightment...

there should be equal balance between all of these

*advanced techniques
*experimental methods
*tests
*plant physiology+manipulation
*environmental engineering


until activity eventuates individual sub-forums in ea distinct category; for the eccentric & scientifically inclined member, guest & mod

thx for stopping by & contributing...

enjoy yourgarden!
