Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the requirements of the SEC for interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted. These condensed consolidated financial statements have been prepared on the same basis as the Company's annual consolidated financial statements and, in the opinion of management, reflect all normal and recurring adjustments which are necessary for the fair statement of the Company’s financial information. These interim results are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2025, or for any other interim period or for any other future year. All intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of December 31, 2024, has been derived from the audited consolidated financial statements of the Company, which is included in the 2024 Annual Report. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in the 2024 Annual Report. On February 12, 2025, the Company filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware to effect a 1-for-10 reverse stock split of the Company's common stock, effective February 12, 2025 at 5:00 p.m., Eastern Time and the Company's shares of common stock began trading on a split-adjusted basis on The Nasdaq Capital Market at the commencement of trading on February 13, 2025, under the Company's existing trading symbol “HYFM”. There was no adjustment to the number of authorized shares or the par value. The Company has adjusted the presentation of all periods covered by the condensed consolidated financial statements contained herein to give retroactive effect to the Reverse Stock Split, including adjustments to net loss per share and other per share of Common Stock amounts.
Use of estimates	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Significant estimates include provisions for sales returns, rebates and claims from customers, realization of accounts receivable and inventories, fair value of assets acquired and liabilities assumed for business combinations, valuation of intangible assets, estimated useful lives of long-lived assets, incremental borrowing rate applied in lease accounting, valuation of stock-based compensation, recognition of deferred income taxes, classification of debt pursuant to certain terms in the Company's credit agreements, recognition of liabilities related to commitments and contingencies, asset retirement obligations ("AROs"), and valuation allowances. Actual results may differ from these estimates. On an ongoing basis, the Company reviews its estimates to ensure that these estimates appropriately reflect changes in its business or new information available.
Fair value measurements	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company has applied the framework for measuring fair value which requires a fair value hierarchy to be applied to all fair value measurements. All financial instruments recognized at fair value are classified into one of three levels in the fair value hierarchy as follows: Level 1 — Valuation based on quoted prices (unadjusted) observed in active markets for identical assets or liabilities. Level 2 — Valuation techniques based on inputs that are quoted prices of similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not in active markets; inputs other than quoted prices used in a valuation model that are observable for that instrument; and inputs that are derived from or, corroborated by, observable market data by correlation or other means. Level 3 — Valuation techniques with significant unobservable market inputs. The Company measures certain non-financial assets and liabilities, including long-lived assets and intangible assets at fair value on a nonrecurring basis.
Inventories	Inventories consist of finished goods, work-in-process, and raw materials used in manufacturing products. Inventories are stated at the lower of cost or net realizable value, principally determined by the first in, first out method of accounting. The Company maintains an allowance for excess and obsolete inventory. The estimate for excess and obsolete inventory is based upon assumptions about current and anticipated demand, customer preferences, business strategies, and market conditions. Management reviews these assumptions periodically to determine if any adjustments are needed to the allowance for excess and obsolete inventory. The establishment of an allowance for excess and obsolete inventory establishes a new cost basis in the inventory. Such allowance is not reduced until the product is sold or otherwise disposed. If inventory is sold, any related reserves would be reversed in the period of sale. During the year ended December 31, 2024, the Company estimated inventory markdowns relating to restructuring charges based upon current and anticipated demand, customer preferences, business strategies, and market conditions including management's actions with respect to inventory raw materials and products and brands being removed from the Company's portfolio.
Revenue recognition	The Company follows ASC 606 - Revenue from Contracts with Customers which requires that revenue recognized from contracts with customers be disaggregated into categories that depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. The Company has determined that revenue is generated from one category, which is the distribution and manufacture of CEA equipment and supplies. Revenue is recognized as control of promised goods is transferred to customers, which generally occurs upon receipt at customers’ locations determined by the specific terms of the contract. Arrangements generally have a single performance obligation and revenue is reported net of variable consideration which includes applicable volume rebates, cash discounts and sales returns and allowances. Variable consideration is estimated and recorded at the time of sale. The amount billed to customers for shipping and handling costs included in net sales was $1,403 and $2,939 during the three months ended March 31, 2025 and 2024, respectively. Shipping and handling costs that occur before the customer obtains control of the goods are deemed to be fulfillment activities and are accounted for as fulfillment costs included in cost of goods sold. The Company does not receive noncash consideration for the sale of goods. Contract consideration received from a customer prior to revenue recognition is recorded as a contract liability and is recognized as revenue when the Company satisfies the related performance obligation under the terms of the contract. The Company's contract liabilities, which consist primarily of customer deposits reported within deferred revenue in the condensed consolidated balance sheets, totaled $2,307 and $2,611 as of March 31, 2025, and December 31, 2024, respectively. During the three months ended March 31, 2025, the Company recognized $657 of previously deferred revenue, recorded customer deposits of $589 and noted $236 of additional decreases primarily due to customer refunds. There are no significant financing components and the majority of revenue is recognized within one year. Excluded from revenue are any taxes assessed by governmental authorities, including value-added and other sales-related taxes that are imposed on and concurrent with revenue-generating activities.
Income taxes	The income tax provision is calculated for an interim period by distinguishing between elements recognized in the income tax provision through applying an estimated annual effective tax rate to a measure of year-to-date operating results referred to as “ordinary income (or loss),” and discretely recognizing specific events referred to as “discrete items” as they occur. The income tax provision or benefit for each interim period is the difference between the year-to-date amount for the current period and the year-to-date amount for the prior period.
Recent accounting pronouncements	In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which requires greater disaggregation of information in the effective tax rate reconciliation, income taxes paid disaggregated by jurisdiction, and certain other amendments related to income tax disclosures. This guidance will be effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires a public entity to disclose additional information about specific expense categories in the notes to financial statements on an annual and interim basis. The amendments are effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. A public entity should apply the amendments either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact that adoption of this accounting standard will have on its financial disclosures.
Restructuring	The Company began a restructuring plan (the "Restructuring Plan") in 2022, and undertook significant actions to streamline operations, reduce costs and improve efficiencies. The major initiatives of the first phase of the Restructuring Plan included (i) narrowing the Company's product and brand portfolio and (ii) the relocation and consolidation of certain manufacturing and distribution centers, including headcount reductions and reorganization to drive a solution based approach. The Company completed the first phase of the Restructuring Plan during the year ended December 31, 2023. As a result of the continued adverse market conditions, the Company implemented a second phase of the Restructuring Plan beginning in the third quarter of 2023, including U.S. manufacturing facility consolidations, in particular with respect to production of certain durable equipment products. Restructuring activities included termination and disposal costs associated with inventory, facilities, and headcount reductions, and non-cash charges consisting of fixed asset and inventory write-downs.
Purchase commitments	From time to time in the normal course of business, the Company will enter into agreements with suppliers which provide favorable pricing in return for a commitment to purchase minimum amounts of inventory over a defined time period.
Contingencies	In the normal course of business, certain claims have been brought against the Company and, where applicable, its suppliers. While there is inherent difficulty in predicting the outcome of such matters, management has vigorously contested the validity of these claims. Based on available information, management does not expect that the outcome of any matters, individually or in the aggregate, would have a material adverse effect on the condensed consolidated financial position, results of operations, cash flows or future earnings of the Company.
