Free AutoCAD greenhouse and hydroponics blocks (DWG): greenhouses, benches, NFT, vertical farms, irrigation, climate control

About sizes and clearances

There is no standard for greenhouse plan symbols. The sizes are typical trade sizes: a hoop house of 6000 x 9600, a Venlo span of 3200, benches 1200 to 1500 wide, an aisle of 900 for people and 1800 for carts. They are common practice, not a rule, so check the structure, snow and wind loads, ventilation area, energy, water and food safety rules and the manufacturer's data against your local rules.

These symbols are our own drawings after common planning practice, and the library is not certified against any standard. Check the sizes, clearances and connections against your project and change the blocks if yours differ.

Frequently asked questions

Are these symbols to a standard?

No. Plan symbols for greenhouses and indoor farms have no binding standard. The blocks follow typical trade sizes and planning practice, and the zone markers show typical values, not code requirements. Check local rules, the structural data and the manual of every product you specify.

What are the growing layouts?

Ready-made houses and rooms as one block each, with walls, doors and the equipment in place: a hobby greenhouse, a nursery house with rolling benches, a hoop house with vegetable beds, a Dutch bucket tomato house, lettuce houses with NFT and with raft ponds, a strawberry tunnel with growing gutters, an aquaponics house, a propagation house, a microgreens room, a vertical farm room and a packing shed. Insert one for a quick layout, or explode it to move single pieces; the same pieces are in the library on their own.

Can I use the symbols in commercial projects?

Yes. They are free to use and modify in your own projects, including commercial ones. They are provided as is, without warranty. Please do not redistribute or resell the library; see the library terms.

Can I use these together with the planting, farm and landscape libraries?

Yes. They use the same units, attributes and insertion rule, so the libraries can be used in one plan. This one adds greenhouses, growing systems and equipment; the planting library has plants and trees, the farm library has barns and livestock layouts, and the landscape library has garden and site pieces.

Can I change a symbol or add attributes?

Yes. Open the DWG, edit a block with BEDIT to change it or add attributes, and save. To update drawings that already contain the block, run ATTSYNC or replace the block. Make a backup first: attribute values can be lost if ATTSYNC is used carelessly.

Are the floor, wallpaper and material patterns hatches?

No, they are blocks made of thin lines. Insert one, scale it to the area you want to show and copy it to cover more (ARRAY), or use it as a legend sample next to your finish schedule. For large areas the hatch patterns of your CAD program are the better choice.

Should I download this library or one of the smaller topic libraries (furniture, doors and windows, bathroom and kitchen, stairs, walls and roofs)?

This one has everything in a single file. If you need only one topic, the topic library holds the same blocks in a smaller file, and the furniture library adds front elevations of the furniture.

Where do I find a ready-made set of these symbols for AutoCAD?

AutoCAD itself ships only a small set of sample blocks, so a full symbol set has to come from a library. Download the ZIP on this page and open the DWG: every symbol is a block. Insert one with INSERT (Blocks palette, Libraries tab, then pick the DWG) or drag it from DesignCenter (ADCENTER). You can also download a single symbol on its own.
