Note: If PPM levels are too low or too high, your autoflower will show symptoms of under or overfeeding.
Hydroponics is a well-known technique for cultivating soilless indoors, this technique consists of soaking the roots in a nutrient solution and lots of oxygen. Using this method means that there is no soil and plants grow in a sterile, inert growing medium.
3. Hydroponic Setups
Deep water culture is a style of hydroponic growing that may or may not use a medium like perlite, coco, or clay pebbles. In a DWC setup, you have a reservoir filled with a mix of water and nutrients, the lid holds special pots or nets with their roots stretching down having part of them submerged in the solution, this way they have nutrients available all day long and can absorb nutrients when they want to.
A simple way to understand it is we measure pH levels to be sure our plant’s nutrient intake is optimal. We measure PPM levels to make sure we are giving the right amount of nutrients to our plant and to ensure our plant is absorbing nutrients.
PPM levels go up for each stage so here’s a table to better visualize them:
The paper-towel method should deliver tap roots from split seeds in just two days. Many commentators will suggest you stick the germinated seeds directly into dirt or just whack them in straight out of the pack and into soil, but that’s not the best way to get your autos off to a strong start. Instead, carefully insert germinated seeds in some peat or root riot cubes for the duration of the seedling stage.
Autoflowering cannabis cultivation always starts from seed. Let’s be perfectly clear and get this straight from the outset: you can’t crop autos from clones. Sure, you can take a cutting from a mature autoflowering plant and probably get it to take root too. But that little shrub will never grow to a decent size because it will transition to bloom far too soon for you to bring more than a snack-sized bud to harvest a few weeks later. This can be a fun botanical experiment or a novelty ganja gift for a friend, but never a proper cannabis plant.
Container Size for Autoflowering Cannabis
The short answer is yes. Modern autoflowering cannabis has evolved so far beyond the disappointing Lowryders of the past, it’s like trying to compare Homo sapiens with a lemur. You absolutely can let your green fingers work their magic on most contemporary autoflowering cannabis strains. The one possible exception being intensive combinations of multiple pruning and training techniques like those involved in mainlining.
Timing is everything when you grow autoflowering cannabis. Just like photoperiod cannabis, you can expect the same four stages of growth as follows: germination, seedling, vegetative, and flowering. However, autos will race from seed to harvest and fly through each stage like a photoperiod plant in fast forward. On average, contemporary autoflowering strains have a 60- to 90-day lifecycle.
Time is always the key factor and there is not a day to waste. As soon as your autoflowering cannabis seeds germinate, the clock is counting down to harvest day. It’s so important to make sure you nurture your seedlings because there really is no time for them to recover from a botched transplant. Early delays will come back to haunt you when it’s time to harvest.
