Beginner Autoflower Grow Tips for Bigger Yields

Frequently Ask Questions

Q. When to switch to bloom light autoflower?
It would depend on the strain, and how long it takes from seed to harvest, for auto-flowering strains. In my experience of 2 auto-flowering hydroelectric plants growing tall, I would start with a light bloom around 21 days

Q. When to put autoflower under lights?
Since auto-flowering plants have short vegetative phases and often grow shorter than photoperiod strains, you usually want to give at least 18 hours of light. This enables robust growth without excessive energy expenditure.

Q. How many watts does an autoflowering plant need?
Well it depends, some people say 150 watts for your first plant then add 50 watts for each additional plant. One successful plant will grow at 150 watts and 250 Grows 2 etc.

Q. How many plants can go under 600w led?
Two months plants can offer approximately 40 g per plant, so you can easily fill a square meter with about 9 and get up to 400 g per 600w. 3-month auto-flowering plants grow much bigger, however, so you should only plant 4 per 600w light.

Q. Can led grow lights burn plants?
Driven lights tend to emit less heat than older devices, and have relatively low light intensity. This has contributed to the fact that you will be able to bring plants as close to the lights as you like and not kill them. This depends heavily on the plant but an 800 PPFD is adequate to harm certain plants.

Q. Do Autoflowers need dark periods?
Technically speaking, auto-flowers require no darkness because, depending on the season, the Ruderalis are accustomed to 24 hours of daylight at times in the wild. They can be grown in any light cycle, provided the temperature conditions are favorable.

Q. What size light for 4×4 grow tent?
For a 4×4 grow tent light supply of 300w to 500w is sufficient for their growth.
