Thanks, Bill, and good morning, everyone.
Net sales for the first quarter were $54.2 million, down 12.9% year-over-year, driven primarily by a 12.6% decrease in volume/mix. The decrease in volume/mix was mainly related to oversupply in the cannabis industry. Additionally, pricing was relatively flat in Q1 as we lapped price concessions made in the first quarter of 2023.
In the first quarter, consumable products represented approximately 76% of our sales compared to 72% in the first quarter of 2023. This higher mix of consumables was led by a year-over-year sales increase in Grow Media products including our own proprietary Roots Organics and Gaia Green brands. During the quarter, we maintained a strong mix of proprietary brands at approximately 57% of our total net sales, relatively consistent to the same period last year.
Gross profit in the first quarter was $10.9 million compared to $11.4 million in the year ago period. Adjusted gross profit was $12.7 million or 23.4% of net sales compared to $14.1 million or 22.6% of net sales. This 80-basis-point increase is primarily the result of improved productivity inside our manufacturing plants. This marked our fifth consecutive quarter of year-over-year adjusted gross margin expansion. And while we are pleased with our progress, we do feel there's some opportunity to further improve upon this metric as we track across the remainder of 2024.
Now a quick update on our restructuring plan. As we previously mentioned, our second phase of restructuring was largely focused on rightsizing our manufacturing footprint, particularly with respect to durable equipment products. We announced today the signing of an agreement in which we are selling the manufacturing equipment and on-site inventory related to our IGE-branded products for approximately $8.7 million in cash.
As part of the transaction, we will no longer be responsible for carrying the heavy manufacturing labor and overhead costs or the investment in costly steel aluminum necessary to build our high-quality IGE products. Instead, post transaction, our new exclusive co-manufacturer will produce our IGE products, helping us to variabilize our cost structure and ultimately improve our profit margin profile on this product set.
We are excited about the prospects for both Hydrofarm and our new exclusive co-manufacturer with whom we expect to enjoy a close relationship going forward. We expect the transaction to close in the second quarter.
Now let me move on to our selling, general and administrative expense, which we dramatically reduced from the prior year period. In the first quarter, our SG&A expense was $19.6 million compared to $24.4 million. Adjusted SG&A expenses were $12.3 million, nearly a 24% reduction when compared to $16.2 million in the first quarter of '23. This was primarily due to a reduction in facility expenses, professional fees, insurance costs and headcount. It is worth noting that much of this reduction is due to the costs we took out as part of our restructuring actions in the first half of 2023.
Adjusted EBITDA was $0.3 million in the first quarter compared to a loss of $2.1 million in the prior year period. The $2.4 million improvement and the 400-basis-point expansion in adjusted EBITDA margin was driven by our improved adjusted gross profit margins and our reduced adjusted SG&A expenses. We continue to demonstrate our ability to generate positive adjusted EBITDA, which is a testament to the effectiveness of our restructuring and cost-saving initiatives along with our focus on proprietary brand sales mix.
Moving on to our balance sheet and overall liquidity position. Our cash balance as of March 31, 2024, was $24.2 million. We ended the first quarter with $120.5 million of term debt and approximately $130 million of total debt, inclusive of finance lease liabilities. Our net debt at the end of the quarter was approximately $106 million.
As a reminder, our term loan facility has no financial maintenance covenant and does not mature until October 2028. We continue to maintain a zero balance on our revolving credit facility. And at this point, we have not borrowed against our revolver for 9 straight quarters.
In the first quarter, we reported cash used in operating activities of $2.3 million, with capital expenditures of $1.4 million, yielding negative free cash flow of $3.7 million. I will remind you that the first quarter is a seasonally low period for our free cash flow, and we achieved a significant nearly $7 million improvement from the prior year period, which we accomplished through positive adjusted EBITDA and disciplined reduction of inventories and working capital levels. We remain on track to deliver our positive free cash flow guidance for the full year.
With that, let me turn to our full year 2024 outlook. We are reaffirming our 2024 guidance, which includes net sales to decline low to high teens on a percentage basis, adjusted EBITDA that is positive for the full year 2024 and, lastly, positive free cash flow for the full year, which includes the continued expectation of $4 million to $5 million of capital expenditures.
To wrap up, we remain on the right path, and we'll continue to control what we can. We are operating profitably despite lower sales levels. Our restructuring plan and cost-saving initiatives have proven effective, and as Bill discussed before, there are reasons for optimism on the demand side of our industry as we look ahead. We are excited about the future of this business, and we look forward to continuing improvement throughout the year.
Thank you all for joining us. We're now happy to answer your questions. Operator, please open the lines.
