Space Fuel Feminized Autoflowering Seeds

Q: When should I switch to bloom nutrients?

Switch at first signs of preflower or when you move to a 12-hour light cycle. Raise phosphorus and potassium while trimming nitrogen slightly.

Q: What training methods suit Space Fuel?

Use LST and topping during early veg. Keep canopy even with ties and remove shaded lower growth after the third node.

Q: How do I avoid nutrient burn?

Start 20 to 30 percent below manufacturer feed. Raise EC gradually and flush if leaf tips brown.

Q: How much light does Space Fuel need?

Veg at 18 hours. Flower at 12 hours. Aim for 600 to 1000 µmol/m2/s at the canopy in flower for best resin production.

Q: How do I prevent mold outdoors?

Space plants 1.2 to 1.5 meters apart. Prune lower foliage and harvest before rainy periods. Keep airflow strong.

Q: When is optimal harvest time?

Harvest when most trichomes are cloudy with 10 to 20 percent amber for a clear-head finish and sustained energy.

Q: How does the autoflower version differ?

Autoflower finishes faster and limits heavy topping. Favor LST and light feeding to protect cycle timing.

Q: How do I increase resin and terpene output?

Use PK supplements in weeks two and three of flower. Drop humidity to 40 to 45 percent in late flower and maintain steady CO2 and light.

Q: How much stretch should I expect?

Plan for a medium to large stretch during the first three weeks of flower. Train early to manage final height.
