Petyoung 12 PCS Self Watering Spikes Automatic Irrigation Watering Drip Devices with Slow Release Control Valve Switch for Outdoor Indoor Flower or Vegetables

Very good idea. They kept my plants watered whilst I was away on holiday. It takes a little time to work out how much drip you need. But after you have worked that out they work very well.

This product did not work. It didn't come with instructions other than what is on the box. Nightmare getting flow accurate and nozzle kept filling with dirt so blocked the water coming out. Bought to keep plants watered while away 2 weeks. Tested for 3 weeks trying different techniques but everytime blocked. We had no confidence in this product so tried a different method.

Does not fit any bottle as states. Do not buy

They are easy to use bit fiddly getting drip right but once done no problem great for keeping tomatoes fed while away

Very difficult to regulate water supply but have still found useful in hot weather

Good to include individual taps to control drip speed. Useful for liquid feed.

Difficult to find bottles which you can use with these. Most bottles remained full after return from holiday

Not the quality I thought thy would be
