I have used drippers too. I ran 50 drippers off my magnetic pulse valve. The output of each dripper was only about 1/50 of a gallon per hour. I used it to grow chili plants and it worked pretty well. I prefer sprinklers though because they provide better dispersal and coverage and are easier...

It would last on my vegetable garden only for about five days. Are liquid ferts expensive? The Osmocote® is fairly cheap and is very easy to apply. Also, what effects might liquid ferts have when they are directly sprinkled onto plant leaves?

Growing vegetables in sand has been a lot like hydroponics. But I use a magnetic pulse valve SpritzWiz™ Intermittent Sprinkler Irrigation that provides frequent waterings and uses very little water. The intermittent pulse valve runs directly from the water tap and doesn't require any...

Johnyquest: "qmmckenna, Im not going to call you a name or anything and turn this into a fight but I dont like you." Fair enough. I am a victim of my own vanity. I want to save the world. Truth is no one can save the world. The world can only be saved by information and knowledge and the...

True. Without freedom to choose makes it harder to make good choices.

Chug says- If you dont advocate any1 growing it including yourself why are you on rollitup.org? Good question. I am on rollitup because I believe you guys are in the world vanguard of the green movement, and are more open to new technologies. If my posts can persuade just just one person to...

Please note that all my comments pertain to growing vegetables in my new vegetable garden. I know nothing about growing marijuana nor do I plan to grow marijuana. I don't advocate anyone else growing marijuana either.

Al B. Fuct - Thanks for your input about problems associated with slow release fertilizers and the need to accommodate the changing needs of plants going between vege and flowering states. A propos, I would like to experiment on my vegetable garden with implantable slow release "tea bags" that...

Thanks. All your insights seem very knowledgeable and I just wanted to pick your brains of your general growing knowledge and how I can use my intermittent sprinkler. I don't know beans about growing cannibis and never will. But I hope I have offered some insights of my own of this new...

Here is a very simple one way system that does not require any pumps. The nutrient system is simple to the extreme too. One way systems have the advantage that they eliminate problems of toxins building up in the nutrients and also eliminates cross contamination problems. I built it outdoors so...

Here are pictures of a vegetable garden in a 100 sq. ft sand box, a SpritzWiz intermittent pulse valve to run four micro-sprinklers , and Osmocote® slow release fertilizer sprinkled on top.

Gemstone Man-"Plus, I'm wondering if scented cat litter will be foul enough to keep deer away also." I live in the foothills of Boulder Colorado and we have lots of deer too. I use my intermittent magnetic pulse sprinkler to keep them away. Whenever I am watering the garden or germinating...

Gemstone Man- "Plus, I'm wondering if scented cat litter will be foul enough to keep deer away also." I live in the foothills in Boulder, Colorado and we have lots of deer too. I have a less smelly approach to keep the deer away. I use a magnetic pulsing sprinkler to scare them away. They bolt...

I live in Boulder, CO. We don't have beach sand here. I went down to a local place and bought truckload of WASHED river sand. River sand is generally washed commercially first before you buy it because it is used for lots of different things, including making concrete. Sand from places like...

Quite frankly, I think sand has lots of advantages over soil. Sand has 1/3 the water potential as soil. That means plants don't have to work as hard to get their water. Weeding of course is extremely easy to do. Sand is also healthier and you don't have to worry as much about diseases and...

Yes. I think it is most definitely possible to grow marijuana in sand. Due to "imperial entanglements" I wont even try growing marijuana myself .... but I am doing something very similar with vegetables. I have germinated and grown vegetables in an outdoor sandbox with my new intermittent...
