Its going to be extra hot the next few days...my plants are very big so they suck water like crazy. I say a day but I'll be gone 2 or so...just depends. I plan on watering heavy the morning I leave...so that'll last for a day and a half before thay getty really droopy. I don't know how the bottle thing would work anyway...it would be out by the end of they day....but that may be long enough. I may go get a drip manifold and rig up something quick..I have drippers and tubing..so I guess I have my answer...there is no quick fix. Thanks for the response guys, yeah I've seen those globe things, I just don't wana buy them...may as well by the manifold thing.
