Stonerdanswered grow question 4 years ago There are a few options to irrigate those plants, one is setting up a drip system connected to a timed pump in a reservoir, another option is using a watering wand connected to a simple pressure pump. You can also DIY a watering wand-like tool to reach those plants while watering (like a large bottle connected to a long PVC tube to reach those hard to reach plants).

Good luck and happy growing :)
