Sure thing! Start with a DIY grow rack—just stack some sturdy pallets and line them with old PVC or bamboo. It saves a ton on shelves. Use reclaimed or rain‑water for irrigation—just a simple filtration system. LED grow lights can be salvaged from old TVs or bought in bulk at a discount. And don’t forget to use a closed‑loop recirculation; it cuts water use by 70% and reduces maintenance. For nutrients, mix a basic compost tea with a little fish emulsion—cheap, organic, and it keeps the plants happy. Finally, schedule a maintenance rota with the neighborhood crew; sharing tools and labor keeps the budget low and the community tight. Happy planting!

That sounds like a smart plan! The rain‑water limits in most cities are usually around 10 gallons per square foot per year for rooftop systems, but check the local code—sometimes they allow a bit more if you have a catchment system that’s well‑filtered. I’ve found that a small rain barrel with a first‑flush diverter keeps the water quality top‑notch and stays within limits. Let me know if you need a quick rundown of the local regulations or help tweaking the draft. Good luck keeping the budget tight and the system green!
