I have read that Jiffy-7 pellets are an acceptable medium in which to start seed. However, in the 1990 catalog of the now-defunct Seed Bank it says not to use them because they are too acidic and prevent germination. Is this true? What is a good pH level for the growing medium?
Cedar Rapids, I A Although Jiffy-7 pots are made primarily from peat moss, which is very acidic, pH adjusters are added to the pellet by the manufacturers in order to raise the pH. They are suitable for starting seeds.
Marijuana grows best in a growing medium that has a pH of 6-7.
I’ve had good results with hard-toroot varieties, such as Big Bud, by using willow water in an electrified water container.
First I take a 4'-6' piece of new growth from a willow tree and cut it into 1"-2" pieces, which I soak in water for a few days.
Then, before I take a cutting (for cloning) I leach the nitrogen from the plant by irrigating it only with unfertilized water for about a week.
I make a small hole through a piece of Styrofoam and insert the cutting. Using the willow water and a water-soluble rooting compound, I float the cutting in a 4"-diameter container. Then I place two 3” copper probes 180 degrees apart and attach them to a 6-12 volt AC transformer at 700-800 milliamps. A small, extra fine air-stone is placed at the bottom of the container; then I attach an air pump to insure the cutting receives enough oxygen. I place fluorescents over the cuttings and maintain the temperature at 6570 degrees. The cuttings root in about a week.

BUD OF THE MONTH
This is a high-quality skunk bud. The plant grew 8' tall and 4' across. It was planted in half a whiskey barrel and survived the hurricane.

GARDEN OF THE MONTH
Here are some pictures of the constant-flow system that I constructed using gutter pipe. The room is lined with metallic reflective material. I use 1000-watt high pressure sodium (HPS) lamps.
It works like this: I place 4" squares of rockwool in the gutters. A simple plumbing faucet regulates the flow rate for each gutter. The water flows the length of the pipe and drains into a pan holding a sump pump. The pump pushes the water to a reservoir above the garden. The water then flows from the reservoir back to the gutters.
I also grow a few plants in 5-gallon buckets. I water these by hand.
Is the amount of water that marijuana smoke passes through in a bong irrelevant as long as the smoke passes through some amount of water? Or is more water better?
Is resin that sits in bong water worth the effort of straining and smoking?
Dr. Uma Bud, Ocean City, MD Water collects water-soluble components of smoke in a bong. These substances are not psychoactive. They are considered irritants and are better left in the pipe than in your lungs. The more water the air bubbles travel through, the more likely they are to be washed of these impurities. The more water in the pipe, the better.
Resin deposited on the surface of the pipe or trapped in water contains lots of THC. The question of whether its worth collecting these particles depends upon how much grass you have, and how badly you want to get high.
PLANT OF THE MONTH
How’s this for an ornamental shrub? This little baby came up voluntarily and grew solely using sheep manure and waste water from the washing machine.

Recently I purchased a selfcontained grow unit. I have tried two crops with no luck. It just won’t bud. Is it possible to grow buds worth smoking with this thing?
Puzzled Warren, Ml
The plants are not blooming because they are receiving too much light during their 12-hour dark cycle. To prevent light from entering, place the unit in a dark room. If this is not possible, then place the unit in a closet during the 12-hour dark cycle.
I have decided to use ethylene in my grow room to try to turn my projected males into females.
I read an article that said ripening tomatoes and apples emit ethylene. Is this true? Does this produce enough to do the trick? When is the best time to use it? I have a 2' x 2' x 5' grow space.
Canoga Park, CA Ethylene is a gas produced by ripening fruit. When it comes in contact with other fruit, it promotes ripening in them. That is why fruit ripen more quickly when they are placed in a paper bag. The concentration of ethylene increases, promoting faster ripening.
Some growers have reported success using ethylene to promote “femaleness” in their plants. Others claim that it was ineffective.
Ripening fruit can be used to create a concentration of the gas in the air of an enclosed space. Rather than using the whole fruit, fruit peels can also be used.
Most growers use commercially produced ethylene, such as “Floral” or other brand names.
The best time to use ethylene is shortly before the plants are forced to flower during the second week of flowering.

I have a growing cabinet that is 4' x 2' x 5'. The inside is painted white. I use an incandescent grow light which I bought in a hardware store. I have had good luck so far. The plant grew from seed to 9 inches in 18 days.
Should I use different lighting?
The Space Cowboy Chillicothe, TX
Incandescent lights are the least-efficient form of lighting there is, and the light spectrum they emit is not particularly good for plants. Although incandescent grow lights have a modified spectrum that has more blue light than most incandescents, they still are not ideal.
Fluorescent tubes emit almost three times as much light as incandescents using the same amount of electricity. Your garden is a total of 8 square feet, so it could use a minimum of four 4' tubes. Adding an additional pair of tubes during flowering would increase the size and compactness of the buds.
A 150-watt high pressure sodium (HPS) lamp emits considerably more light than four 40-watt fluorescents. Although it costs more initially, it actually saves you money over the long run because of its efficiency. It is also less bulky.
