Back in the early 70's I did veggie gardens on two adjacent plots and alternated veggies and a cover crop. When I disked in the cover crop in the fall I would add what ever manure was available, also lime as needed. The next spring I would send soil samples to the state ag lab and based on...

Good point, looks like the experiment has been run and it's as close to certainly OK as one gets in this world.

I too think there will be significant condensate unless you live in aridzona.

If the cooling unit is running when the lamp is started there should be no thermal shock to the bulb. It would only be a problem if the cooling stream was so close or so directed that the area of the bulb that the cooling stream hitting caused the bulb to develop a sufficient temperature...

Thanks for immoral support it's much appreciated :) I had read where you said that elsewhere, but I'm an old coward and this sort of thing is very atypical for me -- so it aint easy Mam :sad banana icon goes here:

I just received Marijuana Botany by R.C. Clarke. I was hoping it would detail the chemistry of drying and curing. From the book: Neither decarboxilation nor isomerzaion requires oxygen. Yet the author goes on to say that the opening and closing of curing jars provides fresh air needed for...

An article giving an analysis of the Obama administration's position on cannabis which is as egregiously anti-science as the previous administration's. Lordy how this chaps my cheeks. :mad: hxxp://opinion.latimes.com/opinionla/2011/07/medical-marijuana-the-deas-science-free-zone-blowback.html

Thanks for the help. I will begin reading posts and print on training so I know what to do if it is required.

I'm looking at building a closed loop drying and curing cabinet using a custom built solid state dehumidifier. I'm still at the research stage but if you're interested and comfortable with basic electrical issues and have some wood working skills I'll post my early ideas. Be glad for someone...

I gather training doesn't mean using a clicker and treats -- or a whip. Ah, yet another wrinkle to iron out. But thanks for the heads up.

I just glanced through some formulas and they seem to confirm my faltering memory that all else being equal the evaporation rate for a given (fixed) RH is independent of temperature. Thus drying at 45 degrees F (7.2 C) seems entirely possible. I'm waiting on delivery of a book that I hope will...

Yes 55" actual room -- effectively from top of pot to x inches away from light. Sorry I wasn't more clear.

Also smokers. You know the drug cartels don't follow safe practices when it comes to pesticides and herbicides.

Beside the prospect of pain relief I think the biggest payoff will be not worrying about inhaling pesticides and supporting the truly evil Mexican drug cartels. And thanks for all the kind words.

Mr Nice Seeds G13 Haze is what I'm thinking about. Still trying to screw my courage to the ordering point. Mr Nice Seeds G13 Haze : hXXp://www.cannabis-seeds-bank.co.uk/mr-nice-seeds-g13-haze/prod_3563.html

I think the way to tell if it might work would be to measure the relative humidity in the frige. The lack of air circulation is definitely not a plus though. I've been wondering about reduced temperature drying. Going to have to dig out a very old book and look again at the gas laws. Why don't...

This shows the light hanger. The cables are attached to a piece of conduit as shown here. I've been thinking about inserting a steel rod into it as a counter weight to make is a little easier to raise and lower. The conduit is shown here.

The two texts on hydroponics that I have read recommend maintaining an H2O2 level of ~ 50 PPM as a prophylactic against Pythium. According to my reading once you have it the whole system needs chemical sterilization. Test-strips appropriate for maintaining 50 PPM H2O2 are available on line. A...

My original design had only one high pressure pump but I'm going to add a second and have them run on alternating misting cycles. If one pump fails the other will keep the plants alive till a replacement can be acquired. The high pressure pumps and and the sump pump will be powered by a UPS...

Hear are some images. Two show the plumbing cabinet that contains the reservoir the the feed and recirculation filters and the UV sterilizer. The third shows the four root tanks and the sump. The black module with wires on the left is the sump pump controller.
