Every plant is a unique individual that doesn’t come with an instruction manual. There is no one size fits all universal schedule. The amount of moisture needed is based on several variables like foliage density, root mass, soil mass, temperature and relative humidity. Understanding these variables is what’s makes a grower a grower. Irrigation schedules will change throughout the course of a plant’s life.

Im figuring it out. Im feedind 3x a day right now for 3 mins. I think im moving up to 5min feedings at .5 gph.

What I would do and do myself is go a little easy on watering after transplants until you see roots out the bottom of the pots or through the grow bags etc. From that you would water a normal cycle and figure out what volume comes out over the cycle. For example in my system I use 1 or 2 gallon pots I want to do 10-20% of pot volume per watering. Roughly 250-500 ml. With that information determine the amount of run off you get per cycle by putting a container under the plants and capturing the run off. Run off should be around 5-10% of the water you put in per cycle. So 500ml you would want to see 50ml per plant if it’s more you need to water fewer cycles per day if the amount is less you need more cycles per day.

Feel free to message me for any additional info

Thank you. I have a schedule right now of 3x a day at 3 mins a feed with .5 gph emmiters .

Careful never watering to run off. Plants consume far more water than minerals. You’ll have salts eventually form causing the pH to tank with such short cycles.

It sounds like you’re doing High Frequency-Low Volume fertigation?

How ever frequent is needed to keep the coco fully saturated. Best practice is to keep the coco between 90-100% saturated. So each feeding event should take place when coco has lost 10% of the water it can hold. You could assume about half of the container volume is water when fully saturated. So in a 5gal pot, 2.5gal is water and 10% of 2.5gal is 1 quart needed of a nutrient solution to get the coco back to 100%. It should be enough so that however much you put in, you should get 10-20% of it as runoff, for 1qt that’s about 1/2-3/4 of a cup. Feeding 3-5x daily is about average for that type of feeding but it’s really gonna depend on what the plant is using. But remember…things don’t have to be perfect. You’ll end up with more mistakes trying to focus on perfection.

Smart move going ahead and starting with auto watering. Hand feeding even just a couple plants like that gets old really fast. I was doing it and I would end up letting the coco get really dry because I didn’t wanna get up to feed. Letting it dry out is the one thing you don’t want it to do.
