E27 12w led light how many hours a day would leave the light on plants

Choosing the right LED to grow light can be tricky. There are many factors to consider, such as the size of your grow area, the type of plants you are growing, and your budget. This article will help you choose the right LED to grow light for your needs. The first question you should ask yourself is, "What type of plants do I want to grow?"

You will need a different light for growing herbs than you would need for growing cannabis or lettuce. A simple way to approach this is to think about what your needs are in terms of a grow light. If you're growing cannabis, you want a light that has high lumens and a good color spectrum for the plant. If you're growing vegetables, you want a light that has high lumens and a good color spectrum for the plant.

If you're growing cannabis, you want a light that has high lumens and a good color spectrum for the plant. If you're growing cannabis, you want a light that has high lumens and a good color spectrum for the plant.

Are you talking about a "regular" spider plant? The kind of houseplant that has extensions drooping down with "new" little plants on the ends? Generally speaking I'd say "normal" day length for lighting - just getting light from (best) a south facing window, or east or west if south isn't an option. (Not north). If you're using artifical light, then, again, matching the regular day length in your location.

Yellowing leaves and browned tips, although I am not an expert, seem often to indicate over watering but it is reckoned impossible to over water a spider plant due to the origins of the plant which is a sort of a tropical grass used to warm humid conditions of indirect light..
Perhaps it is being under-watered or positioned in direct light. Water it well each time but allow the soil to dry out between waterings and feed occasionally in the growing season. Misting the leaves might help...

Never pour water over plants when it is very hot it causes leaf problems as you mentioned , use it on the soil, have you fed the tomatoes because they need food as we do, the leaves showing wilt is responding to direct sun a bit of shade may help.

Growing Requirements for Rex Begonia Plants Rex Begonias grow best in bright, indirect sunlight coming from an east or west window.
Fluorescent grow lights are also an excellent alternative to natural light for these plants,
and in many cases will intensify the foliage colors.
When potting, set the plant with the crown slightly above the soil line.
They should be planted in a porous, slightly acidic planting mix that contains some peat moss
and leaf mold. African Violet potting mixes work well for Rex Begonias.

Allow the top 1inch of soil to dry before watering, then water thoroughly.
Over watering can lead to root or crown rot! Wet foliage can cause problems with mildew.
Always use room temperature water when watering house plants.
House plants should never be allowed to stand in water for more than a few hours.
Painted-Leaf Begonia plants thrive with daytime temperatures of 70-75
and 60-65 at night. NEVER lower than 60!
They require a humidity level of at least 50 percent and appreciate periodic, light misting.
Provide additional humidity by setting the plants on shallow trays filled with moistened pebbles,
or a humidifier, especially during the winter months.

Feed actively growing plants in early spring and again in early summer with a slow-release plant food,
or every 2 weeks using a quarter strength dilution of a soluble, complete fertilizer (23-19-14).
Decrease feeding in early fall and stop altogether in the winter. Do not over-fertilize!

Your Begonia Rex may go dormant in the winter and possibly drop its leaves.
If this happens, continue to water sparingly until spring when new leaves will re-appear.
If your Rex is growing where it only gets light from one side ( a window sill),
turn the pot a quarter turn each week to maintain even growth.
Foliage color may fade under low light conditions. Consider using a grow light.

Remove any dead leaves and other debris around plant regularly.
Rex Begonias enjoy spending the summer in a shaded part of the garden.
Always be sure to check for insects and pests before bringing your plants back indoors!
Rex Begonias are susceptible to attacks from mealy bugs.

If you won a plant aquarium you should keep the lights on for 9-10 hours a day, try avoiding a direct sunlight on the aquarium which leads to a rapid growth of algae. Don't ever leave the light on for 24 hours because just like you the fish their sleep and it is very necessary in order to keep them alive.

No. The lights on your aquarium should never be on for more than 10 hours a day. The fish and plants need to rest and by leaving the lights on all the time; they will get stressed out and may even die.

Theamount of time you should leave your aquarium light on depends on a number of factors. If you don't have plant life, I would saythat about ten hours a day is a safe average. However, not all fish take to light well so it depends on the type offish you have.
