I totally fell in love with these awesome drawings! Totally my style. Lovely. *and educational* My favorite is this one with the two beautiful surfer girls enjoying a spliff . “Hi, my name is Jessica and I am the artist behind Rosemary Rain. I was born in Arizona, where I still reside with my amazing boyfriend of 6 years (Jason) and our 3 cats; Jack (named after Jack Bauer) Louis (Named after King Louis XVI) and Miep (Named after the amazing Dutch woman who helped Anne Frank’s family and saved Anne Frank’s Diary)

I am an Art History student, Part-time Painter, and I work Full-time in the Mortgage Industry.My inspiration comes from my childhood, pastels, Marie Antoinette, my travels and my dreams of travels.When I was a little girl, I was always making something. I remember taking my brown paper lunch bags and turning them into hand puppets, or going on road trips with my family and bringing along markers and paper and drawing the mountains as we drove by. In ten years, I would love to own a little row house along the canals of Amsterdam, spending my days painting, creating, exploring, traveling, learning and making a difference.”

Hemp Technologies- Building a Hemp House

mission is to enrich and enhance the health and welfare of our planet and those living on it through reductions in toxicity levels and increased use of sustainable building materials that reduce energy cost. Building a greener, healthier tomorrow, TODAY!?”

The stand behind their product and are a model for what great things can be made using hemp. Here are some hemp facts:

*Henry Ford’s first Model-T was built to run on hemp gasoline and the CAR ITSELF WAS CONSTRUCTED FROM HEMP! On his large estate, Ford was photographed among his hemp fields. The car, ‘grown from the soil,’ had plastic panels made from a mixture of 70% cellulose fibers.

*Hemp is the miracle plant of our time, breathing in 4x the carbon dioxide (CO2) of trees during it’s quick 12-14 week growing cycle. Trees take 20 years to mature vs 4 months for Industrial Hemp! Our forests are being cut down 3x faster than they can grow! One acre of hemp produces as much cellulose fiber pulp as 4.1 acres of trees!!! (Dewey & Merrill. Bulletin #404. U.S. Dept. of Age. 1916)

Hemp Technologies will travel to your school, college, University or company and present a 4-6 hour seminar/workshop on theory and practical applications of Industrial Hemp + Lime in building. This seminar includes practical, hands-on demonstration of using Hemp/Lime for building a sample wall.

Indoor Hydroponic Inline Exhaust Fan – How-To

Hi I’m Darren here at the Grow Show. I’ll be speaking today on inline fans and how to choose one to best suit your growing environment. There are many key factors you want to think about when choosing an inline fan. The first will be your fan diameter. Your fan diameter will determine the effectiveness and speed at which your air moves in your room . Most of the fans will be either 6 or 8 inches. When thinking about which fan will suit your needs, you want to think about the volume of your room. To get the volume of the room you multiply the width times length times height and you will find the cubic feet. Then you want to match that to the fan you are going to use in your environment. When choosing a fan you want to consider the volume of the room you are occupying and the efficiency of the fan. Its important to get as close to a 1 to 1 ratio as possible. Another thing to consider is the number of lights you are running in your room and how much heat they are putting off. If you are running multiple 1000 watt lights and multiple hoods, you’re going to want to run a fan with a higher volume rate to keep your room and bulbs cooler so your lights can sit closer to your plan canopy line. We have three main brands of fans. We have our popular Active Air line that come in 4, 6, 8, 10, and 12 inch occupancies. The larger the fan the more air you will move. You may think “I have a 6″ reflector, can I run an 8 inch fan? ” Yes, you can. You can use a duct reducer and connect it to your 6 inch hood. The reduction will reduce your flow rating, but it will still be greater than if you just used a 6 inch fan. The great thing about an Active Air Fan is it comes with a 5 year in-store warranty. If anything was to happen to your fan, you can bring it to the Grow Show and we will make sure its working and get you back to your garden. We also have Vortex fans. Our Vortex fans have a higher flow rating and come with a 10 year in-store warranty. We also have Ostberg fans, but they only come in 6 inch flange size. The last thing you want to consider when choosing a fan is if you are running a carbon filter in your room. If you are, you want to be sure you are optimizing the flow rating. If your filter has a higher flow rating than your fan, you’re going to want to upgrade your fan because you are just limiting the effectiveness of your filter. For example, if you’re using a filter with a 600 cfm flow capacity, but only using a 6 inch fan with a 400 flow rating, You’re not optimizing the effectiveness of the flow rating of your filter. That concludes our introduction to in-line . If you have more questions please visit us at the Grow Show in Ann Arbor on Stone School Road or visit our website at

Powdery Mildew

o you have powdery mildew on your medical marijuana? Yikes! Powdery mildew in the grow room? That’s nothing to play with. It can spread very quickly and attack all of your plants. Powdery mildew prevents the plants from growing by messing with their photosynthesis. Also, its hazardous to people as well.

Our solution?

1. Remove leaves that are completely covered in it.

3. Pour in a spray bottle and spray it all over the top and bottom of each leaf. As it dries, it removes the powdery mildew.

Another very important tip : Clean up the room and keep it clean.


Combat Pests with Strong Defense

Handling pest control in a grow room can be an exasperating task, but with a good defense and careful monitoring we can effectively control our indoor territories. Michigan growers have it easier than some other medical marijuana states, but basement growers can especially face some persistant enemies. Some pests found in Michigan are: mites, spider mites, gnats, mold, mildew, white flies, powdery mildew, leafhoppers, bees, and wasps.

In desperate situations, an indoor gardener may resort to drastic measures using a systemic, which are chemical pesticides that will actually make the plants themselves lethal to pests who feed on it. However, this leaves the plant infected for as long as 60 days or more! Most indoor garden supply store do not even carry systemics like Avid or insecticides like Diatomaceous Earth due to special licenses needed to place them on their store shelves.

Without resorting to these chemical weapons, we do have “friendlies”, or beneficial insects on our side. The ladybug, for example, can be a great guard and will eagerly devour aphids, mites, white flies, and scale insects. Make sure to have a glass shield on the grow lamp when releasing friendlies, for without one they will fly straight for the light and burn up! Also, do not spray any pesticide for two weeks prior. Ladybugs and other friendlies can be picked up at the local grow shop.

Lately some very good organic pesticides have shown up on the market shelves. Most use neem oil . Neem oil is a vegetable oil pressed from the fruits and seeds of Neem, an evergreen tree found in India.
Some great concoctions that have been developed to take out a multitude of enemies. A great one, my personal favorite, is Organocide. I have witnessed this solve many pest issues. Of course, the sooner we catch a problem, the easier it is remedied. Monitor your plants closely and always try organic methods first before resorting to desperate measures.

I will state that no pesticide can compete with a strong defense. Modern growers spend a great deal of time, work, and budget on their grow room control and cleanliness. I asked some close friends that are caregivers in California what pesticides they like lately, and they replied, “None, we don’t have any pests.”

What? California doesn’t have pests? It’s true. Rather than battle the beasts, these experienced growers practice defensive management and spend their efforts on cleanliness and control. They: seal the room, keep plants off the floor, hygrometer measuring and alarms, use oscillating fans, sweep, mop, control humidity, spray the outside perimeter, and silk screen the air intakes.

Using a de-humidifier to waver the humidity level creates an uncomfortable, unstable environment for pests to lay eggs and reproduce. A humidity level that fluctuates between 40% to 50% is ideal. The oscillating fan helps the room air become unstable for flying insects. Cleanliness is overlooked many times as well. Be careful what clothes you wear in to your grow garden. Some gardeners will be working on their outdoor garden and transit right into working on the indoor plants as well, trafficking enemies in.

When cleaning, use “green” cleaners such as Simple Green or a new one, Greenterpene.

One final note- growers just getting started should seal and monitor their room before putting a single plant life form in their new indoor garden. This is an essential step that many beginners overlook, but one that can save headaches and unnecessary work in the long run.
