In summary, our cannabis care routine consists of:
- Starting with good, biologically active soil
- Mulch with biodynamic accumulators
- Top dress with malted barley every week or two
- Add silica & powdered aloe vera to regular waterings, as well as mixed into teas and foliar sprays
- Top dress with other meals (kelp, alfalfa or neem) every month – this can be replaced with botanical teas

How to help seedlings survive?
I have three more tricks to help your seedlings survive. First, place a small oscillating fan so it blows the seedlings gently, from side to side. This will help to strengthen their stalks, so the plants grow to be sturdier later on. Another tip is to use reverse osmosis water, rainwater, or tested and clean well water.
How to grow a plant in hydroponics?
There are several supplements and nutrients you can use to encourage root growth: 1 Vitamin B, such as that found in a hydroponics product called B-52. For plants less than three weeks old, I only use 1–2 ml of this product per gallon of water, and I don’t use it every watering cycle. It contains small amounts of nitrogen, phosphorus and potassium, which are added benefits for early growth. 2 House & Garden Roots Excelurator: A high-priced but highly effective root stimulant product. 3 Beneficial bacteria and fungi. In nature, plant roots evolved with microbes that protect, stimulate and enhance roots. You can add those microbes into your root zone using hydroponics products made especially for marijuana. Such products include Advanced Nutrients’ Voodoo Juice, Tarantula and Piranha. I recommend 1–2 ml per gallon of water for each of these products, starting two days after your seedlings produce their first set of true leaves. As your seedlings gain leaves and height, begin to follow the manufacturer’s dosing instructions.

Can you feed seedlings too early?
Many growers make the mistake of starting to feed their seedlings too early, too heavily, or both. When a seedling only has a few sets of true leaves (by “true leaves,” I mean leaves with serrated edges), it has minimal root development and can’t handle high nutrients doses.
Can overwatering kill seedlings?
Other than overwatering, which is a sure way to kill seedlings, over-fertilizing is also a leading cause of seedling failure. It makes a big difference if you’re growing in inert media such as rockwool, soilless mix or coco coir, in pure hydroponics such as deep water culture, or in soil.

How much water do seedlings need
One common problem that occurs when trying to care for a seedling is giving them too much water. It is actually less of an issue having to do with too much water, but actually has more to do with too little oxygen reaching your plant’s roots.
Overwatering your seeds
Since a young plant’s tiny roots absorb much less water than their more mature counterparts. If you water as much as the container can hold, these tender roots will not be capable of taking it all in. This situation occasionally referred to as “overpotting,” leads to overwatering. So how do you prevent this situation from happening?
Underwatering
If you’re sure you haven’t been watering your plants too often or too much and they are drooping or wilting, the culprit could actually be a lack of water. Sometimes people who know about the common occurrence of overwatering seedlings have overcompensated, therefore actually watering their plants less than is required.
What kind of nutrients
Giving your plants nutrients can come with its own issues. If you give your plants too high a dosage of nutrients, for example, it will turn into nutrient toxicity. Your plant’s leaves will have tip burn and turn darker in color.

Why do seedlings droop?
This essentially drowns a seedling’s tiny root system, starving the plant of oxygen and causing it to droop. Overwatering can also occur when a plant’s container is too big or too small. When growing a small seedling in a big pot, the excess soil can hold water for days in areas untouched by the plant’s roots.
How long does it take to take down a cannabis seedling?
Cannabis seedlings are extremely fragile; armed with nothing but frail roots and a small set of cotyledons (that first set of small rectangular leaves), minor stressors can take down your seedlings in just a couple of hours.

What is the function of a plant's substrate?
One of the functions of a plant's substrate is to serve as a site for air exchange between the roots and the environment.
