not with these plants...but I have used the 2 liter or 1/2 gallon bottles to water tomatos, squash, cukes, etc before. Worked great. That was so it wouldn't run off in my garden and get the water right where it needed to be. I have thought about adding those to these plants...maybe next time. I'm on a first grow of 25 plants, 8 varieties
But how tacky is a 1 liter Pepsi bottle sticking out of your pot? Lol
and i can see it a now, a commericial on tv for a pepsi two liter at the store and right at the end it says, oh and you can also use it to water your marijuana plants when you go on vaction.
idk if it works, but it looks like it's constantly bubbling. Which means it's always dripping. Which means it'll empty in like 2 minutes. What a waste of money!
It doesn't constantly bubble. Just when the soil is dry and there is air to be relased. I saw one of these for sale on the counter in my local hydro shop. I didn't pay it much attention though. It wasn't this brand, a different one. But I am interested in if it works or not.
