Need some advice

i have 20 plants going about an hour away from my house, I can only water them once a week due to my work shedual. is there anyway to keep my plants watered when am not around?

I've heard of 5 gallon buckets with small holes drilled in the side and planted near the roots but that would be quite a task with 20 plants. Make sure there's plenty of mulch and perlite in your soil and hope that it rains

you can get water crystals, silicates that will hold water for well over a week. these are a must for outdoor growing, if you can't check your plants.
