1. The method of cultivating macroalgae propagates, which comprises:
(a) providing a clean, grease-free core
of a plastic material;
(b) inserting the core within an expandable netting;
(c) loosely packing mature, reproductive
macroalgae within the space surrounding
the core and bounded by the netting;
(d) placing the packed macroalgae in an
environment conducive for growth to
establish propagates of said macroalgae
on said core; and
(e) removing the adult plants and cultivating
the remaining propagates in an environment conducive to growth.

2. The method of claim 1, further characterized by:
(a) said propagates being removed to a
growth environment consisting of a
protected, artificially or naturally
lighted, moisture-charged atmosphere.

3. The method of cultivating freshwater and marine
macrophytes of the type naturally growing in water comprising the steps'" of:
(a) providing a controlled atmospheric
environment;
(b) exposing said environment to light
sufficient to support growth of said
macrophytes ;
(c) placing live macrophytes in said
environment in a position exposed
to said light; and

JUR A
_ OV.PI (d) wetting said macrophytes with water
of the type in which they naturally
grow to maintain only a film -of water
on said macrophytes substantially
throughout their growth period.

4. The method according to claim 3 wherein:
(a) the atmospheric environment is
enclosed and exposed to direct
sunlight.

The method according to claim 4 wherein:
(a) the wetting of said macrophytes is
effecting by spraying said atmospheric environment with said water
to produce a water charged atmosphere,

The method according to claim 5 wherein:
(a) the atmospheric environment 'is
charged with up to five orders of
magnitude less water per cubic volume
than normally present in the same
volume of water in which the macrophytes naturally grow.

The method according to claim 5 wherein:
(a) the water charged atmosphere is
maintained at a relative humidity of
substantially 100%.

The method according to claim 5 wherein:
(a) the spraying of water is effected
by atomizing said water with air.

9. The method according to claim 5 wherein:
(a) the spraying of water is effected
by atomizing said water with air
and at least periodically with air
and CO-.

10. The method according to claim 5 further comprising the step of:
(a) controllably introducing nutrient
10 additives into said water prior to
said spraying operation.

11. The method according to claim 5 further comprising the step of:
15 (a) maintaining the temperature of said
environment within a substantially
uniform range promoting optimum growth
of said macrophytes .

0 12. The method according to claim 11 wherein:
(a) the temperature of the environment
is at least partially controlled by
varying the particle size of the spray.

25 13. The method according to claim 5 wherein:
(a) said enclosed environment is in a
housing located on the ground; and
(b) said water is obtained directly from
a groundwell.
30
14. The method according to claim 13 wherein:
(a) the macrophytes are those naturally
growing in sea water; and
(b) the water used in spraying the
5 environment is sea water.

15. The method according to claim 5 further comprising the step of:
(a) draining the live macrophytes of
water in excess of said film.

16. The method according to claim 15 wherein:
(a) the live macrophytes are placed in
said environment to permit free
circulation of water charged air
in and about them to effect said
draining .

17. The method according to claim 16 wherein:
(a) the live macrophytes are loosely
placed in said environment and
tumbled to periodically expose all
of them to said light.

18. Apparatus for cultivating freshwater and marine macrophytes of the type naturally growing in water comprising :
(a) means providing a controlled
atmospheric environment;
(b) means for exposing said environment
to light;
(c) support means for supporting said
macrophytes in said environment said
support means being adapted to loosely
support said macrophytes and being
further adapted to permit light, air
and water to pass therethrough;
(d) wetting means for wetting said macrophytes with water of the type in which
they naturally grow to maintain only a

'B film of water on said macrophytes
substantially throughout their
growth period; and
(e) tumbling means for tumbling said
macrophytes in air to periodically
expose all of them to said light.

19. The apparatus according to claim 18 wherein:
(a) the wetting means includes a
10 I plurality of spray means located
within said environment for spraying
said environment with water to produce a water charged atmosphere.

1520, The apparatus according to claim 19 further including;
(a) means for maintaining said environment
with up to five orders of magnitude
less water per cubic volume than normally present in the same volume of
20 water in which the macrophytes
naturally grow.

21. The apparatus according to claim 19 wherein:
(a) the spray means includes means for .
25 mixing water with air and CO- for
atomizing said water and introducing
it along with said CO- into the
environment.

3022, The apparatus according to claim 19 wherein:
(a) the spray means includes control means
for varying the size of the water particles introduced into said environment
to at least partially control the
35 temperature of the environment.

23. The apparatus according to claim 19 wherein:
(a) said tumbling means includes
spray means.

24. The apparatus according to claim 19 wherein:
(a) said tumbling means is adapted
to impart motion to said support
means to tumble said macrophytes.

25, The apparatus according to claim 19 wherein:
(a) said support means includes a
plurality of cylindrically shaped
rotary racks constructed of an
open mesh for loosely supporting
said macrophytes internally thereof
and for permitting light, air and
water to pass therethrough; and
(b) means for horizontally supporting
said racks for rotation about their
longitudinal axes for tumbling the
macrophytes to periodically expose
all of them to said light.
