GSC Autoflower in 5.5 weeks ... What should my light be set to?

GCandy · Nov 21, 2024

Hey all

Quick question as im not sure if I want my light on 100% or 75% atm? ... I own a 100w (from the wall) unbranded Qboard n unfortuanlty it came with no suggested lighting guide.

The plant is 5.5 weeks old and currently in the bloom/stretch phase (I think see pics). Ive always had my light 14-12 inches from the top of the plant & it gets between 49-52 DLI atm.

There is a lot of conflicting info online n Im not sure if I want to be leaving my light @ 75% until the stretch has finsihed or If I need to be giving it the most light it can get right now?

Advice would be helpful

Thx for reading

Watch your plant for signs of stress, and adjust from there. Plants will vary in their preferences and tolerances, so there is no perfect number to set as a guide.

Edit : also, take notes and write down anything you do, especially if there’s a change in routine. Take notes on what you observe too. You’ll be able to go back and often see where you may have gone wrong.

A light meter indicates how much light is falling on your plant. Your plant tells you how much light it can use.

At 100 watts, even growing in a 2' x 2', you're not going to get a large crop. The size of a cannabis crop can be estimated by the DLI that the plant receives over the course of the grow and a 100 watt light for a 4 square foot area is only 25 wats sq meter. The best thing you can do it turn it up to 100% and get the light as low as possible.

How big is your grow area?
