New To Hydro, What are Possible Problems With Hydroponics

Good afternoon world! Pat here, I’ve been growing in coco for some time now (years). & I’ve finally made the point to switch over to Hydroponics. If anyone would like to share their experience in doing so I would love to hear some first had testimonies. Possible problems, solutions to those problems & so on! Please share!!!

Make sure you meter your water regularly, as that is what your plants need you to do in order to have a successful grow.
Good luck
