First Time Grow-- Dumb Flowering Question

[Wevie Stonder]

Hey All,

I'm just about to flip my room of Casey Jones to 12/12.

I'm running 2 CAP ebb and Grow systems. So far, they're awesome! This is my first time doing hydro, and I've got a silly question:

Do I feed when the lights are off too?

My girls are getting pretty tall (24-30") and sucking up a lot of h20.
I Can't imagine letting them go 12 hrs with no water, but I don't want mold or PM either. What's normal for ebb & flow systems?

Also, how many times day should I feed for?


Thanks, y'all!

how often are you watering now? you wont want to start watering them less...

I dont use hydroton as a medium, but I remember a friend saying he floods every 4 hours in his table with dog kibble.

I'm doing hydroton--

we've been doing 4 feeds over the course of 19 hours, about one every 4.5 hrs.

So, doing waterings every 3 hrs while lights are on, and 12 hrs without would be bad?

I'm confused.

Feed in the dark or not?

not sure whats confusing about dont feed them less then you are now

feed with the lights off.

I would do a cycle during lights out. Your plants are seriously transpiring during lights out. In my system they drink quite a bit during lights out. More then a gal per plant up to 3. The RH % is not going to change that much during lights out because you water them. JK

My bad on letting this conversation go.

So, to sum up: yes on feeding with lights off? How many times?

How many times total a day should I be feeding?

I've got them in 2 gallon pots with hydroton, some of them are pretty tall, like 4-5 feet, others more like 3 ft. They are 2 weeks into flower now.
