About Imperial Seedlings Guide
What this site is, its connection to the domain's past, where its figures come from, and the rules every guide follows.
Imperial Seedlings Guide is an independent guide to growing plants from seed and from seedlings, written for home gardeners in the United States, with one section on the basics of industrial hemp farming. From about 2020 to 2024 the domain imperialseedlings.com belonged to a store called Imperial Seedlings that sold hemp seedlings and transplants to farms. That store is no longer at this address, and this site has no connection to it: it sells no seedlings, seeds or plants, takes no orders, and cannot answer questions about orders, strains or plants the former store sold.
What the guides are for
The guides explain how to raise vegetable and herb transplants at home and get them into the garden at the right time: timing from the last frost date, mix and containers, light, temperature and water, hardening off and planting out, crop-by-crop notes, diagnosing seedling problems, and planning with the USDA Plant Hardiness Zone Map and frost dates. The hemp section continues the subject of the old site in a different form: the agronomy of growing industrial hemp from transplants and the federal legal frame, in plain words, for farmers.
Where the figures come from
Every temperature, distance, number of weeks and legal figure on this site comes from a single fact sheet written from primary sources: the University of Maryland Extension and Clemson Cooperative Extension for seed starting, transplanting and crops, the USDA Agricultural Research Service for the 2023 Plant Hardiness Zone Map, NC State Extension and NOAA's National Centers for Environmental Information for frost dates, and for hemp the Congressional Research Service, the USDA hemp rule (7 CFR part 990), the USDA Agricultural Marketing Service and Oregon State University and University of Vermont Extension. Each guide is checked against that sheet before it is published, and a figure that is not on it does not appear. Where two sources give different figures, the guides say whose each is.
What the guides do not do
They name no seed companies, products or plant varieties, sell nothing and recommend no hemp strains. They make no health or medical claims about CBD, THC or any other compound. The hemp pages are general information, not legal advice: growing hemp requires a license under a state, tribal or USDA plan, the federal definition of hemp changed in November 2025 with parts taking effect later, and only your state department of agriculture or USDA can tell you the rules that apply to your farm.
