I am familiar with Craig and Helping Hands; I don't disbelieve what is being charged against them. I am sorry that this is how it went down, but he was not running a legal business; doesn't matter if its marijuana or donuts, you need to abide by legal business laws and regulations. A few months...

So much is involved with Prop 19, I'm just not sure how detrimental many of those effects may be. Senate bill 1449 was a great help for us, and I hope medical patients are still able to receive all they need in future years. Legalization is a tough thing to do correctly..

I'm not sure if you guys are up to date on what happened this past week, but just wanted to post my article here for you guys to read. It really shows that some of the individuals operating dispensaries are just looking to make money and NOT putting our patients first. This kind of activity...

Pics please. Make sure to go over your room for light leaks, timer mistakes??, check nutrient schedules and everything. Make sure your dialed on schedule to rule out any human error than maybe start looking to genetics but its doubtful. Good Luck

1+ grams per watt is always a great goal for an accomplished grower. Easier with indica then sativa, but great hybrids out there too. Cheers :leaf:

60-75% weight loss in water during drying process. Surprising eh?

Basically the bud is no good. Its dangerous to smoke mold in any form and not recommended. I would place it in the freeze immediately and make hash out of it, preferably an ISO variation to have the alcohol kill the mold spores. Next time make sure the bud is dried correctly. If you are...

You can definitely run the 4" flanges and ducting with your 6" Vortex. I would recommend calculating your air ventilation needs by CFM and cubic feet of the room. Calculation #'s and explanation here. http://www.medicalmarijuanagrowbank.com/hydroponics/ventilation/ It sounds like your tent is...

Depends on the strain and setup. I used to average about .7grams per watt with Master Kush in a 1000watt setup with soil and drip feeds. Once I changed over to soil-less mediums and better nutrient programs I was able to get .9grams per watt out of the same genetics. Mostly I'd say soil is a...

Haha there's not much logic behind your madness but I would like to comment on the "unknown" and "bag seed" breeding. You never know how good the genetics are until they are cultivated correctly!! Just because some bag seed isn't the best smoke does not necessarily mean the genetics are poor...

There is a color guide per kelvin scale on my website. Check it out, its great to compare artificial lighting to outdoor as well. http://www.medicalmarijuanagrowbank.com/hydroponics/lighting/ Just remember, blue for veg and red for flower is the general rule for fruiting plants. Cheers!!

Great tips and info guide right here http://www.medicalmarijuanagrowbank.com/hydroponics/drip-irrigation/drip-feed Just make sure to keep lengths and sizes consistent or there will be inconsistent flow pressures resulting in different amounts of feed per plant.

You need to PH your water. - Add all of your nutrients - Test PH - Add PH down, retest and feed around 6.0-6.5 in Veg for soil Cheers!!

i would not worry about purchasing from a hydro store. your all good.

Probably best to buy from online wholesalers, you can get some great prices. A good digital ballast will run around $275-$300, non-digital will come in around $150. 1000watt hood will run about $40-50, a "parabolic vertical reflector" is what your looking for. Hortilux 1000watt HPS lights...
