FACILITY & REQUIREMENT CALCULATOR
Calculate what your facility needs.
Use your facility data together with the CANNA grow-schedule reference to estimate product use per crop cycle, build a practical 20 L + 5 L pack plan, and review the calculation before sending your facility requirement to CANNA Thailand for quotation coordination.
Your facility
Shared multiplier for all enabled sections. Fractional cycles are supported.
Turn off for Start, Calmag or Control only. Each complete section calculates automatically.
Finishing / flush
These days are already included in Total flower days. Example: 63 total = 56 feeding + 7 finishing. This field records your program; it does not recommend flushing.
Extended flowering plan: Extra flower-feeding days repeat W3–W5 rates after W5, then continue W6–W8. This is a planning assumption to review for your crop, not a crop-specific recommendation.
| Stage | Days | Schedule phase | Solution input |

Base Nutrient & Additives
Your main Coco or Substra program. Select the products you want included in the facility requirement.
CANNAZYM is optional: standard 25 ml/10 L (2.5 ml/L), from D6 in this reference program. Increased rates for reused medium need a separate review. Product guide
Complete one-part nutrient for seedlings and rooted cuttings before the main grow guide. It is calculated as a separate early-stage period, not added on top of the base nutrient period.
Reference rate: 40 ml/10 L (4.0 ml/L). In Plants mode, leave Start plant count blank to use the main facility plant count.
Optional water-conditioning calculation. Calmag is not added automatically from EC alone; use a rate that matches the applicable label and your source-water plan.
Count only the water you actually plan to treat. This subtotal is not added again to irrigation-water totals.
Uses Veg + flower-feeding water only. Start water is separate. Water-only finishing is always excluded.
Enter the rate you have verified for your water and applicable label. Official regional guidance differs, so this calculator does not choose a universal Calmag dose for you.
Separate foliar planning. Never calculated from irrigation volume, and no application frequency is assumed.
Reference estimate only. Check the applicable local label and crop suitability before use. These US reference rates do not establish permission for use in Thailand.
Use protective gloves/clothing and eye protection. Test a few leaves/plants first; stop if damage appears. Higher concentration increases burn risk. Avoid unaffected flowers. Mix/agitate and use promptly.
US unit conversion uses 128 US fl oz per US gallon. The denominator is water before adding concentrate. Pack format is left unallocated until confirmed.

RECOMMENDED REQUIREMENT
Calculated requirements
Each completed section is shown separately. Base A+B products include a matched pack plan; Start, Calmag and Control show concentrate litres with pack availability to confirm.
Calculation logic & assumptions
READY FOR A QUOTATION
Send your facility requirement for review.
The calculator recommends a low-overage mix of 20 L and 5 L packs. Copy the summary or send it to CANNA Thailand. We can review the technical and product requirement, then coordinate quotation and order arrangements with your assigned CANNA partner.
20 L + 5 L pack logic
Required volume is rounded up to the next 5 L. The calculator then uses as many 20 L packs as possible while keeping excess volume to a minimum.
FACILITY REQUIREMENT
Send the calculated requirement to CANNA Thailand.
Add your contact details and send the requirement generated above. CANNA Thailand will review the technical and pack requirement, then coordinate with your assigned CANNA partner for quotation and order arrangements.
