Gelato yield by the numbers

Gelato is a cross of Sunset Sherbet and Thin Mint Girl Scout Cookies. Sherbinski and the Cookie Fam released the numbered cuts in the mid 2010s. THC tests at 20 to 26 percent. Yield is the weak point of the strain.

Breeder listings put indoor production at 350 to 450 grams per square meter, which is about 12 to 16 ounces on a 3x3 ft tray. Outdoor plants in full sun finish at 400 to 600 grams each. A high output commercial cut hits 600 to 700 grams per square meter. Gelato sits below that line. The gap closes with canopy management and light intensity, not with more nutrients.

Start with the right cut

Gelato 33, Gelato 41, and Gelato 45 are the cuts buyers ask for by number. Seeds throw several phenotypes. Some lean short and dense, some stretch and yield less. A clone from a known mother keeps yield and terpene profile stable across a room. If you run seeds, veg them out and take clones from the two heaviest plants before flip.

Room settings

Indoors, hold air at 68 to 79 F (20 to 26 C). Keep relative humidity at 60 to 70 percent in veg and 40 to 50 percent in flower. Veg for 24 to 30 days from a rooted clone. Flower runs 8 to 10 weeks. Most cuts need the full 10. Outdoor harvest lands in late September to mid October in the Northern Hemisphere.

Gelato Strain: Medical Uses and Effects Guide

Flower stage light: 600 to 900 µmol/m²/s PPFD, or a daily light integral of 35 to 45 mol/m²/day. In a sealed room, 800 to 1200 ppm CO2 supports those numbers and adds weight. Gelato plants stay at 35 to 47 inches (90 to 120 cm) indoors after topping.

Training for weight

  1. Top above node 4 or 5 at day 18 to 21 of veg. This makes two main tops.
  2. Bend branches outward with low stress training every 2 to 3 days. Keep the canopy flat.
  3. Install a SCROG net at 8 to 12 inches above the pot. Weave tops through the squares until 70 percent of the net is full, then flip to 12/12.
  4. Defoliate at day 21 and day 42 of flower. Remove fan leaves that shade bud sites.
  5. Strip the bottom third of each plant at day 14 of flower. Lower buds get no usable light.

A flat, even canopy is the single largest yield factor for this strain. Gelato grows bushy with short internodes, so light penetration drops fast without training.

Feeding schedule

Run EC at 1.2 to 1.6 in veg and 1.6 to 2.2 in flower. pH 5.8 to 6.2 in coco, 6.0 to 6.5 in soil. Gelato takes heavy calcium and magnesium. Add cal-mag at 1 to 2 ml per liter from week 2 of veg. Cut nitrogen at week 5 of flower and raise phosphorus and potassium. Flush with plain water for 7 to 10 days before harvest.

Late flower and harvest

Night temps of 59 to 64 F (15 to 18 C) in the last two weeks bring out purple in the leaves and bracts. Check trichomes on the calyx, not the sugar leaves. Cut when 70 to 80 percent are cloudy and 10 to 20 percent are amber. Dry at 60 F and 60 percent humidity for 10 to 14 days. Cure in jars for 2 to 4 weeks. Bud density rises in the cure, so wet weight tells you little.
