so many nice strains gonna waste away

Why are so many dudes on this site overwatering the plant's.For f@uck sake water once a week let dry then re water this way you will all end up with far bigger root mass.Has long has when you do water you set the ph right add the right nutrients and then wet the plant through then leave to dry then wet the plant through 7days later get what i'm saying.Cannabis don't need watering every day or other day to get a big yeild.The dryer a plant becomes it will start to send out small roots insearch of water till it finds some.But if you water every day the plant will have a very small root mass and no where near has big a yeild.

this is why noobs should start with bagseeds, cuz they kill good seeds

At one point, more than ten years ago, I used rockwool slabs with cubes on top and fed twice a day. I found that I had a monstrous root mass. *shrug*

This depends on the size, size of everything.
Light wattage, pot size, plant size, root mass size. I have some plants I have to water twice a day, others once every 3-4 days.

You must live in a cool climate to water once per week, or grow small plants.
Mine look half dead after 4 days without water, and I use 16 litre pots in a grow tent.

I used 11 litre pots with clay pellets on top to stop evaporation from the soil and they would be dry as hell in a week.

4-5 days would of been about right for them.
