 my 1st ebb&flow grow and questions
Well, thanks to a whole lot of great advice from all of you I am now 3 weeks into my hydro grow. here's the setup:
heating vent in floor is now air intake, small fan just to move some air
cut hole into the attic for exhaust from 6" blower
blower sucking heat from 1000watt hps
airflow in room is great, temp 75-78
two clothes storage trays for the plants, 2 gallon net pots
rubbermaid res, 2 airstones and the 264gph pump
using general hydroponics 3 part system plus calmag because of the coir
medium is 50% coir, 50% perlite
milwaukee ph/tds meter
light is 12 on 6 off.
currently feeding once a day in veg state
plants grew beyond my wildest dreams, heights 5"-9"
from seed in 3 weeks & very lush with leaf.
the way they are growing i'm thinking i might need to go into bloom in another three weeks or knock out the ceiling altogether!
about ppm. currently at 1200 with ph at 6.0. is my ppm ok or too high?
do i really need c02? does it impact potency?
thanks in advance for any advice,
