In a reasonably sized pot the initial soaking of the soil means they are unlikely to need water for at least a week. Right now all they need is light. I use a 600W dual spectrum lamp that I turn down to 250W at this stage. The light needs to be close enough to the plants to prevent them from stretching, but far enough away not to burn them. Generally, an autoflower produces 20 to 60 grams per plant. This is derived from the content of the final dried bud. This number however is not absolute, the most difference being if the plant grows outdoors and is healthy. In such scenarios, an autoflower yield can be as high as 160 from a plant. Step 3: The screening process. With the screen in place, it’s time to start low-stress training your autoflowers in earnest. The aim is to expose each branch to the maximum amount of light for productive yields of dense, resinous buds. Start LST your autoflowers into the screen with the outer branches first. To begin with, you need to choose the right time of the season to start growing your autoflowering cannabis. Generally, they grow from seed to harvest within 8 to 12 weeks, depending on genetics. The best time to grow autoflowering cannabis relies on various factors like climate, genetics, and environment. Mid to late flower your plant doesn’t need nitro, and Micro is 5-0-1. Very late flower, I cut off Micro entirely and just stick with the Grow and Bloom. I average like 3-6 ounces per plant using GH trio. Autoflowers typically flower for 5-8 weeks, although some strains may take up to 10 weeks. Unlike photoperiod plants, autoflowers start flowering based on their age, not light exposure, leading to a quicker 8-10 week seed-to-harvest cycle. This allows for multiple yearly harvests. Yes, autoflowers prefer direct sunlight. They don’t require the strict 12 hours on 12 hours off schedule that feminized seeds do, but autoflowers will grow better in direct light. Try placing your container in an area that gets at least 8 hours of sunlight per day. PAR is an electromagnetic light of wavelengths ranging from 400–700 nanometers. The PAR for cannabis wavelength is known as infrared when above the 700 nm range and usually has a deep red color. At 400 nm, the light turns blue, but when below that range, it becomes ultraviolet. Are you still wondering how much PAR for autoflowers is best? If it is above 7, that means the soil is alkaline. Autoflowering cannabis plants thrive in a little acidic soil, so keep your soil pH ranges between 6.2 and 6.5. You could, of course, experiment with making your own soil. If so, you’d only need peat moss, some compost, perlite, and vermiculite mixed in a 3:3:2:1 ratio. How much PAR for flowering. To activate the flowering stage, weed plants need to receive 12 hours of light and 12 hours of darkness. During these 12 hours of light, the flowering plants will need light with a minimum of 460 PPFD . The PAR values can be increased to between 620 and 1000 nm for better yields. 3gEWBAL.
