CRIS: Cannabis Grow Journal

CRIS is more than a grow journal. It combines strain planning, clone management and
real data analysis into one tool that follows your grow from seed to harvest — stored
locally on your device, with no account and no server. Built for adult home growers who
want to understand their grow, not just log it.

🧬 STRAIN LIBRARY & MATCHING
• Keep every strain with breeder, type, indica/sativa, flowering time and height
• Track your seed stock and average cost per seed, purchases recorded as lots
• Matching tool: set your limits (flowering time, height) and CRIS rates every strain
with a traffic light — the best fit for your tent rises to the top

✂️ CLONES & MOTHER PLANTS
• Bought clones tracked as lots, with stock and cost per cutting
• Take your own cuttings straight from a mother plant — with counts for cut and rooted,
and the cost carried over from the mother automatically
• Rooting rate and cost per clone at a glance

📊 GROW WITH REAL DATA
• pH and EC trends for both feed water and runoff, week by week
• Climate values: temperature, humidity, PPFD, VPD and CO₂
• Strain history: yield, efficiency and issues per strain, evaluated across all your grows

💶 KNOW WHAT A GRAM COSTS
• Electricity (kWh × price), nutrients (ml × cost/L), substrate, seeds and clones,
hardware depreciation — added up automatically into total cost and cost per gram
• See exactly where your money goes and what home growing really costs you

🌱 DAILY GROW DIARY
• Watering, feeding, climate, training, photos and notes — all in one place
• Feeding schedules by week (ml/L or absolute doses); adjust a single week at any time
without changing the template
• Phases from germination to harvest, cover photo and weekly history per grow
