How high should my LED light be above my plants?
24-36 inches
How does no light affect the plants?
How Light Affects the Growth of a Plant. Plants get energy from light through a process called photosynthesis. This is how light affects the growth of a plant. Without light, a plant would not be able to produce the energy it needs to grow.
Does Topping increase yield?
Does topping really increase yield. Some people claim topping does not actually increase yield, because the colas get smaller every time you top. But, it has been shown that the cumulative yield is much heavier when you top your plants. So yes, topping really increases yield.
How did the amount of light affect the growth of plants gizmo?
Look at the graphs for Plant heightand Plant mass. How did the amount of light affect the growth of plants? The more amount of sunlight the shorter the plant is. But the mass increases with more amount of sunlight.
What do you think plants need to grow and stay healthy gizmo?
1. What do you think plants need to grow and stay healthy? Plants in general need soil with a decent amount of nutrients and need to be watered regularly and need to have a decent amount of sunlight each day. This allows the plant to stay healthy and grow.
How many nodes should I have before flowering?
You start counting weeks when the plant has 4-5 alternating nodes. This is when you would feed them nutrients at about 400ppm. my plants are 4 weeks out from seed my Auto blue dreams are flowering already. they are only3-4 nodes high at 8″.
How long should I keep my plant in the dark before harvest?
24-72 hours
Where are Bud sites on a plant?
Instead, all bud sites are located on the plant canopy and receive equal amounts of light. This allows all buds to grow to a desirable size and density. The increase in size and quality of buds means that less plants are needed to create the same size crop.
How do I keep my internodes tight?
Keeping the blue spectrum during the time the plant stretches the most keeps the nodes closer n tighter, which equals more bud sites. It is also helpful to run mixed spectrum during the balance of flower to keep it tight. Use both MH and hps to bring the crop home.
When should I top plant the second time?
Go by your feelings, once the plants look strong enough you can start topping and training them. Look for secondary growth at the lower nodes, that usually means that it is safe to top the plant. When the plant has formed the fifth pair of leaves, it should be ok for you to remove the main shoot.
What are the 3 things that plants need to make food?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Are big fan leaves a good sign?
Giant fan leaves are a sign your girls are in an environment they like- possibly just a little to high on the rh, causing them to grow larger in order to transpire more efficiently.
What do you think plants need to grow and stay healthy?
Plants have specific needs – light, air, water, nutrients, and space – to survive and reproduce. Almost all plants need these five things to survive: Light.
Can you top a plant too late?
It is ok to top now. You might want to wait two weeks after topping to go 12/12.
Can I cut a bud off my plant?
The answer is quite simple. The buds at the top of the plant will be biggest and will be ready to cut first. Go ahead and cut them. Let the lower branches finish flowering for another 2–3 weeks and they will grow to full potential.
What do plants need to survive?
Plants, like all living organisms, have basic needs: a source of nutrition (food), water, space in which to live, air, and optimal temperatures in order to grow and reproduce. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN).
How do you know what plants need?
For most plants, the golden rule is to see if the first inch or so of soil is dry. If dry, this is an indication that the plant needs water. If there are leaves that have shriveled or are dry/discolored, the plant might need a little extra water than a regular routine.
How do you fix stunted plant growth?
Stunted Growth – Vegetable Seedlings and Transplants
- Plant in well-drained soil high in organic matter.
- Use high-quality seed and transplants.
- Keep soil evenly moist and fertilize with a balanced soluble fertilizer after seedlings emerge or after transplanting.
How long do plants take to recover from topping?
Yes, you pretty much just traumatized your plant, they need time to recover before you force flowering on them. You should have topped at maybe 4 weeks or so, so they’d be healed again and ready for flowering. Give it a good 10-14 days maybe before flowering.
Can I harvest the top half of my plant?
You might want to get an answer to this question, “Can I harvest the top half of my plant?” Yes, you can harvest the mature buds on the top section and liberate the leaves and branches to permit the better infiltration of light to the lower part of the plant.
What is my plant trying to tell me?
A common sign your plant is stressed is if it’s dropping leaves and flowers. Stressors can include lack of water, over watering, temperature change, less light – you name it. If the problem isn’t too little or too much water, or something else easy to identify, have patience.
Why does my plant only have 3 leaves?
Like I mentioned above, single blade leaves or a three leaf weed plant is primarily caused by a fluctuation with photoperiod lighting. While rare and unlikely, other factors such as heat stress and bugs can also lead to this phenomenon. However, most cases occur because of plants with photoperiod stress.
How late can I top my plants?
You don’t want to top a cannabis plant too soon. The plant must be able to handle the pruning process. A cannabis seedling can range from 1-2 weeks old, and you would not want to top the plant at week three. It would likely not survive, even though at week three, it should be in the vegetative stage of its development.
How does the amount of light affect the growth of a plant?
Light is the driving force for photosynthesis, a plant process that changes sunlight into chemical energy. A general rule of thumb is that 1% more light will give you a similar percentage increase in plant growth, resulting in a 1% higher yield. All plants require light and CO2 for photosynthesis.
At what node should I top?
We recommend topping to the 4th, 5th, or 6th, node. When you top the plants, you are completely removing the upper growth. No new growth will develop from the growth tip that has been cut. This allows the lower lateral growth to assume the dominance.
