CEA ROI FAQs
What’s a good yield per ft²?
Flower canopy commonly ranges 30–50 g/ft² per cycle depending on genetics, environment, and experience. Set a realistic value based on your data.
Should I enter price per pound or per gram?
Either. Choose $/lb or $/g and the calculator converts automatically. Prices vary widely by market, grade, and contract.
How are maintenance and depreciation used?
Maintenance is a % of CapEx per year. Depreciation is straight‑line (CapEx ÷ years). Both are added to OpEx for break‑even, margin, and ROI.
How is financing handled?
If you add a financed percent, we compute a standard amortized monthly payment from APR and term, then include annual debt service in post‑debt payback.
Is this tax or accounting advice?
No. This is a planning tool to benchmark scenarios. Consult your financial professional for tax/accounting treatment.
The timing of the delivery is extremely expedient, and the beneficial nematodes are very effective. I will definitely purchase from this company again and I highly recommend their beneficial nematodes.
I've never had an issue with any order, ever. That's for myself, and when i've also sent things to other growers. I LOVE the BioNova line so much, thank you for keeping it here!!
I entered without knowing what I needed to complete my setup, and left with gear that suited my needs and confidence in using it. The team described everything simply, answered all my questions without making me feel rushed. Rarely does one find this service model today!
We ordered the triple threat for our raised bed garden of around 21 beds and our greenhouse. We have terrible problem with pests and hate using pesticides so we thought why not.
We applied them all through out and then decided to come in the house with the microscope and see what they looked like and they were Alive and moving well! I cant say that they work yet but we will be ordering again in the spring and reapplying! I believe they have plenty of time to do some damage this year still!
Kentucky zone 6-7 for reference on our growing season.
