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.
$38 for ice and a small little sachet. For the same price I could get 30 sachets directly from the source don't trust these guys! Go to TipTopbio.com the website listed on the sachet!
First time last time customer. These guys are definitely cut off!
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!
