Ideal Temperature For Marijuana Plants Too low. Marijuana grown indoors functions best at moderate temperatures between 68 and 77°F (20-25°C) during the light period and a drop of no more than 18°F (10°C) to 60°F (15°C) during the dark period. CO2-enriched plants will produce more at a marginally higher temperature of just under 82°F (28°C).

- For instance, the optimum soil temperature for seed germination of carrots is 80°F, for parsley and lettuce 75°F, and for spinach 70°F. The minimum temperature required for these crops is 35°F.he realistic soil temperature is somewhere between optimum and minimum; it is the temperature at which you should plant to insure maximum success. For instance, the optimum soil temperature for seed germination of vegetable crops, such as cucumber, cantaloupe, okra, pumpkin, squash and watermelon, is 95°F.

The plant shows their fondness for a decreased in TDS/EC when applying a lower pH by really satisfying increase in growth speeds. The most favourable temperature for hydroponic mixture would be in 75°F or 23.8°C. During this particular temperature, a lot of elements are absorbed the highest and also the oxygen is largely available and ready to be dissolved. The increase in temperature can speed up the photosynthesis though prevent too much increase of temperature greater than 78°F to 25.5°C.

How to Grow Tomatoes Tomatoes are a warm-season annual that grow best when the soil temperature is at least 55°F and the air temperature ranges between 65° and 90°F. Tomatoes require from 50 to more than 90 warm, frost-free days to reach harvest. Tomatoes are commonly grown from seedlings started indoors and transplanted into the garden.

The Effect of Soil Temperature of Tomato Growth Cool soil temperatures affect the tomato plant negatively, especially if they persist for more than a week. Temperatures dipping below 55 degrees Fahrenheit stops both pollen production and overall plant growth. As a result, you see visible stunting to both foliage and fruits, if the plant produces fruits at all.

Bulletin #4135, Storage Conditions: Fruits & Vegetables A general rule for vegetables is that cool-season crops should be stored at cooler temperatures (32 to 35°F), and warm-season crops should be stored at warmer temperatures (45 to 55°F). There are exceptions to this rule, though. Table 1 lists optimum storage temperatures for commonly grown Kansas fruits and vegetables.

Bulletin #4135, Storage Conditions: Fruits & Vegetables Fresh fruits and vegetables need low temperatures (32 to 55°F) and high relative humidities (80 to 95 percent) to lower respiration and to slow metabolic and transpiration rates. By slowing these processes, water loss is reduced and food value, quality and energy reserves are maintained.

What Temperature Will Damage Tomato Plants? Extreme temperatures cause tomato plants and fruit to suffer damage. Tomatoes (Lycopersicon esculentum) grow well in U.S. Department of Agriculture plant hardiness zones 2 through 10 when planted in the full sun.This fruit is commonly categorized as a vegetable.The sizes of the tomatoes vary from tiny, grape-sized fruit to large beefsteak tomatoes. The plant itself is a bushy vine that needs support in order to grow upright. When temperatures fall too low or soar too high, the tomato plants and fruits suffer.emperatures below 55 degrees Fahrenheit are too low to grow a healthy tomato plant. The low temperatures interfere with normal pollination of the blossoms, which drop off the plants. Fruit fails to set, so no tomatoes are produced.

What Conditions Do Tomatoes Need to Grow? Starting seeds indoors six to eight weeks before the average last spring frost date, or directly sowing them in the garden after the last frost date once soil temperatures reach 60 F or warmer will produce seedlings. A temperature range of 65 to 75 F is best for tomato plant growth. When temperatures drop below this range, growth slows. Tomatoes will grow in temperatures warmer than 75 F, but you'll need to water more often to prevent wilting.

Greenhouse temps for tomato and pepper seedlings I start tomato and pepper seedlings in an unheated greenhouse with heat mats. I'm not sure exactly what temperature it is right around the plants, but with the warm soil and a plastic dome cover over them, they do very well. The ambient air in the greenhouse gets into the 40s at night, but never below freezing.

- Zone 10, for example, has minimum low temperatures from 40 to 30 degree. These areas are found in southern Florida, California and Texas. Most of Northern Utah is in Zone 5, which has a minimum low temperature of -5 to -10 degrees. Plants are given a hardiness rating based on these zones, Goodspeed says. This helps when selecting unfamiliar plants for the landscape.

Will Frost Hurt a Tomato Plant's Fruit? For plants and fruit to develop properly, nighttime temperature should be greater than 32 degrees Fahrenheit with daytime temperatures of at least 60 F. Otherwise, plant growth with be stunted and fewer fruits produced. Even a light frost can kill tomato plants and damage their fruit.rost Protection. Tomato plants may survive a brief frost, but a hard frost, when temperatures plunge below 25 F for more than four hours, will almost certainly kill tomato plants and harm fruit.

Tomatoes require from 50 to more than 90 warm, frost-free days to reach harvest.Tomatoes are commonly grown from seedlings started indoors and transplanted into the garden.row young seedlings on at 60° to 70°F; allow a gentle breeze to rustle over young seedlings each day so that they grow strong stems. About four weeks after germination, about two weeks after potting up seedlings the first time, pot them up again to 4-inch pots.
