So, let's say you were unable to get to your guerrilla grow for 2 weeks. (not because of security.) I know you're supposed to water every 3-4 days, but will the plant have a chance of survival if it goes without water for 2 weeks? This is assuming that it does not rain and there is no timed watering system. Would it depend on the age of the plant? Thanks. *Also any ideas on homemade watering systems like a drip or something?
Weed plants don't need much any water really. I've been growing outdoors since April I have never had to water my plants once. Unless you live in a region going through a drought then maybe you need to water once a week if that. Every 3-4 days is a lot. They arnt garden plants they are weeds. They can handle low water very well. They prefer it actually. You will slow down theyre growth watering often. I never water except when its my water nutrient mix once a week. Ur grow should be fine. Unless you live in Nevada or something.
Also depends on the soil type. Sandy soil needs water more often than a clay base soil. Lots of organic matter helps.
sometime more water less often is good. every time i water i use 5 gallons. once the plant is about 8" tall. its hot where i'm at. so 5 gallons is good for 4 days. when your plants get big they can drink up to a gallon a day. i grow in my back yard, so i can water when i want to. Stinkie....
Just look at the other plants growing near your MJ. If they look healthy without being watered your plants will probably be alright.
I usually don't like leaving them un-watered for more than 2-3 days if temps in 90s+, depends alot on rain, humidity, etc. Water crystals are pretty awesome though, I haven't yet come back to dry holes, small plants though.
a good drip system is just to cut a little hole in a big jug of water (at least two liter) and bury it near your plant. The water will slowly drip out into the soil under the plant. I dont know how long this will keep the water moist for because ive never done it. Another thing you could try is making a rain catch - something trashcan sized with a funnel to stop evaporation, and maybe a screen to stop bugs reproducing (if you care) put it out there before you have watering problems. You could even rig up a drip system with this too...
