INTRODUCTION
MrSoul's
hydro system is a modified slab and tray, in which the
slabs or rockwool have been replaced with clay grow
rocks. MrSoul finds that this setup works better and the
expanded clay medium is reusable.
4 x 4 CELLS
The grow space is divided into 4' x 4' cells,
over each of which a 1000 hps is centered. Each cell
consists of 5 Hyrofarm Quantum RW slab trays (four
parallel, one perpendicular) which are filled 2" deep
with Hydroton.Three inch rock wool cubes are partially
buried in Hydroton, 4 plants per tray. The DynaBloom
nutrient solution (1200 ppm/6.0 pH) is being pumped to
each plant site by a Chapin Spray Tube (N type) on a
schedule of 20 minutes ON and 10 minutes OFF. The trays
were modified to allow one inch of flooding.
AN
INCH IN EACH TRAY
Above, a close look at the
business end of a tray before the clones go in, showing
the Chapin Spray Tube (Chapin Watermatics Co.) as well
as a plastic cup MrSoul modified into an overflow to
create the water level (he just cut the bottom out of
the cup and notched the side to the desired level). The
nute solution picks up lots of oxygen from the spraying
and also in the cascading overflow through 2" PVC tubing
enroute to a remote reservoir (in a cool room) where a
"bubble wand" located under the pump adds even more
oxygen. Supplying oxygen to the roots is the KEY to
growing!
EACH CLONE GETS ITS OWN SPRAYER
Above is a view of the underside of the canopy
showing the 3" RW cubes half-buried in Hytroton. The
water level in the trays is about an inch deep. The
Chapin sprayers are normally inserted into the cube's
wrapper, but in this pic they're lying on the surface of
the Hydroton. Each clone gets its own sprayer & they
run 24/7. MrSoul tried on/off cycles but found it works
as well or better spraying 24/7.
When growing a
heavier variety like Genius, MrSoul harvests between 1
-1.25 lbs per 1k light.
