Myself and my roomate have an E&F setup. (i provided a picture toow) i was wondering how often they should be watered... we dropped the watering times from 3 times a day for 15 min a pop to 2 times a day for 20 minutes a pop. then when i woke up...bad... plants were so thirsty they looked like they were about to shrivel up lol. not a problem now, but I could really use some help figuring out a good watering schedule... and if anyone has any good ideas(drawings or something?) of a cheap way to make a E & F system that would be helpful as well. Im going to be building my setup in 3 weeks, after my seeds start growing. oh yeah, the blue tub with the rock wool is what my seeds are in. I could use some more suggestions on the best way make a seed into a plant lol.
i do make sure the rock wool stays wet, or at least very moist. so, lets recap...

Watering schedule( I know not all are the same, but pointers for finding the best for me would be awesome)
any cheap(i mean cheap to build) ideas on an ebb and flow system. or pointers.
best way to take a seed and have it grow(and how much water they should have as well) This forum is amazing so far. Thanks for helping me out.



BTW, i pushed the seeds in 1/2 way and added very diluted nutes to them when i first started seeding. and the plants we have have almost trippled in size in about a week. we keep the water at 6.5ph. and close to 50% humidity and almost 80 degrees. were vegging with a metal halide. and i do know about hps and halide light for veg/flowering. this is our and my first actualy hydroponic setup so ANY tips would be amazing!


UPDATE: just as i was writing this, the plant are back to normal. but i could still use some basic guidelines on watering. (how much is too much on avg, should we put a hydrometer inside the tub with the roots? ETC) THANKS AGAIN!!
