thats awsome fear .. its bear season on the wast coast of canada , i just got my license ..lol.. Ive been growing outdoors for over 7 years now , and when your gurillia growing you want to get in get out . without messign around . to less the chance of getting caught . that serpentine crap would be ok for a couple in the back yard , but try doign that to 500 or 1000 .. i watter al my plants with a gas powered pump , it has 3 inch inlet / outlets . it pumps 48 cubic meters a minute . I usually walk the water and nutrients to them , then do some quick matience and then im gone , all is accessed by boat , so no worrie of thiefs just cops in choppers.. like the other dude said its better to give them alot of water , beause it may be a week before your return .. also try adn watter at night so the watter gets absorbed better and doesnt evaperate . thats a big help.. if u have problums with animals , i use this stuff called scoot , its a white past , u mix it with water and spary your plants with it . it makes you plants taste awfull.. but dont use it when there budding .. by then any animal will already have had the bad exoperiece and wont want to try it again .. works awsome haven lost a plant due to eating in a long long time .. i had a bear sit on a fat bush one time though ..lol.. had to fence it ...lol... i hope i have helped ya a bit .. but if i were you i wouldnt worry about those techniques , just use the FIM and you will be fine , or u can pinch them , oh and also try and pic a spot that have watter near by and your plants will watter them selves . roots search for grd watter ..
