ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.

         The following discussion should be read in conjunction with the
attached condensed consolidated financial statement and notes thereto, and with
the Company's audited financial statements and notes thereto for the fiscal
year ended December 31, 1995.

         RESULTS OF OPERATIONS.   Net sales in the third quarter of 1996
increased approximately 50% to $7,290,157 from $4,870,767 in the third quarter
of 1995.  For the first nine months of 1996, net sales increased approximately
14% to $15,781,570 from $13,860,391 for the same period in 1995.  This increase
was primarily due to the acquisition of Pima Gro Systems, Inc., effective July
1, 1996.

         Cost of goods sold and gross profit in the third quarter of 1996 were
$5,580,061 and $1,710,096, respectively, compared with $3,788,781 and
$1,081,986, respectively, in the third quarter of 1995.  Gross margin increased
to 23% from 22% in the third quarter of 1995.  Cost of goods sold and gross
profit in the first nine months of 1996 increased to $12,381,980 and
$3,399,590, respectively, from $10,971,556 and $2,888,835, respectively, for
the same period in 1995.  The increase in cost of goods sold and gross profit
was attributable to the acquisition of Pima Gro Systems, Inc., effective July
1, 1996.

         Selling, general and administrative expenses increased $126,519 for
the quarter and decreased $229,930 year to date.  The increase for the quarter
was attributable to the acquisition of Pima Gro Systems, Inc. effective July 1,
1996.  The decrease during the nine (9) month period was directly the result of
management's cost reduction efforts throughout fiscal 1996.

         Third quarter interest expense decreased to $224,016 from $250,024 in
the third quarter of 1995.  Interest expense for the first nine months of 1996
was $511,471, or a decrease of $215,708 from the same period in 1995.  This
decrease was attributable to the retirement of certain debt obligations.

         As a result of the foregoing, the third quarter 1996 reflects net
income of $362,864, as compared to a net loss of $(317,134) in the third
quarter of 1995.  Year to date net income of $689,059 compares favorably to a
net loss of $(668,306) in 1995.



                                      8
<PAGE>   9
         As a result of the Company's cumulative operating losses from prior
years, no provision for income taxes has been made.  As of December 31, 1995,
the Company had net operating loss carryforwards totaling approximately
$5,500,000.  Utilization of the Company's net operating loss may be subject to
limitation under certain circumstances.

         LIQUIDITY AND CAPITAL RESOURCES.  The Company has Revolving Credit
Facilities in the aggregate amount of $2,700,000.  Outstanding balances and
letters of credit against these Facilities totaled $1,133,600 as of September
30, 1996 reducing the balance available to $1,566,400.  The Company has
historically financed its operations principally through the sale of equity and
debt securities and through funds provided by operating activities.  Cash and
cash equivalents decreased by $3,079,637 as of September 30, 1996.  The primary
utilization of cash was for the acquisition of Pima Gro Systems, Inc. and for
equipment purchases and significant reductions in accounts payable and long
term debt.

         During the period ended September 30, 1996, the Company expended
approximately $1,343,775 for capital equipment purchases.  Additionally, the
Company completed sales of certain assets for gross proceeds of $1,134,691.
These assets had an aggregate net book value of $842,391, resulting in a
recognized gain of approximately $292,300.

         As of September 30, 1996, the Company had long-term borrowings in the
aggregate amount of $8,331,291, the current portion of which was $3,923,244.
The Company increased its long-term borrowings by approximately $1,368,346
during the first nine months of 1996. This increase in debt was primarily
attributable to Notes issued and Notes assumed in the acquisition of Pima Gro
Systems, Inc., effective July 1, 1996.

         At September 30, 1996, the Company had negative working capital of
approximately $(852,000).  This is directly attributable to the acquisition of
Pima Gro Systems, Inc.  The Company plans to restructure certain notes payable
and short term debt in the fourth quarter of 1996, which will significantly
reduce the current portion of notes payable and long term debt and thereby
increase working capital. Additionally, the Company plans to continue to meet
its current obligations with cash provided from operations.  Management
believes that the Company will be able to return to positive working capital in
the fourth quarter of 1996.
