MMPR Soil or Hydroponics?

I hear you!...we crushed with RDWC, it keeps calling out to me....but non-recirculating is safer for sure.
Not so sure on your take on the heavy metal issue.

Nice feedback folks, thanks

Most NHPs are cultivated outdoors in soil and have the same heavy metal limits as in the MMPR. Why would it be a problem with marihuana when it isnt with all other crops (including all the food we eat). Heavy metals only include lead, mercury etc. and typically are not a problem.

No grower I know, uses soil indoors

My first reaction was "Hey I grow with soil indoors." I do add sand though not, silt or clay on purpose. Currently moving to True Living Organics incl poop, various amendments, all organic, though I guess by the strict definition, still not "soil".

Soil by definition needs to have sand, silt, and clay, interestingly only the organics are optional.

You don't combust and inhale the food we eat. Thats the difference.

i would go aquaponics, organic and no medium at all. more complicated though so as a compromise just go straight water with org. nutes. keep the temps low and the o2 high - should keep pythium at bay.

omg....this thread is back...too funny

I know a few people who have tried LED, and talked to many suppliers, and I would stay away from LED. They simply do not have it ready. Other than traditional lighting, the only alternative that has impressed me is induction for veg.

not sure where you have been looking
leds seem to be at an interesting stage now
they are able to compete with hps and in some cases out yield hps
the downside i can see at this stage is the initial cost of leds and the durability of leds

i have hps ballast that are 15 years old that still work
bulbs last 2-3 years before they need replacing and cost next to nothing
led may not be able to compete with this but can be fixed relatively easily

for me personally i will try them at some point when i decided what light to test first
the novelty of growing without the need to move such a huge volume of air
through the plants to control heat would be interesting

folk growing on larger scales each led will pay for its self and some more on the first harvest
an advantage with led will be rooms can be filled without heat issues
the present and future looks bright for leds

"they are able to compete with hps and in some cases out yield hps"

>pictures or it never happened[please no links]


"for me personally i will try them at some point when i decided what light to test first"

> one would usually back up a statement like the first one here with some thing else than the second statement..

Hey skunk, thanks for dropping by...
I change my bulbs every 6 months, you go 2-3 years?

There are lots of advantages with LED for sure, I just haven't had any positive (yield) feedback from anyone I know.

I feel the same way. I know LED technology has come a long way recently, but I think the whole LED industry really hurt themselves by pushing too hard, too soon in the very early stages when LED grow lights were nowhere near as advanced as they are now. Too many companies made all sorts of ridiculous claims about what their LED lights could do, with zero evidence to back it up. There were (and still are) a lot of outright rip-off artists when it comes to companies selling LED grow lights, and I think all of this just put growers off and left a horrible first impression of LED grow lights in general.

I have no doubt that today's LED lights today are capable of amazing results, but it's going to take a lot of empirical evidence to win over most experienced growers.
