If plants are crowded too closely together, in the daytime when they consume much more carbon dioxide than they release, then the carbon dioxide level drops rapidly, gentle air movement then is essential. AU79-37

Carbon Dioxide Comments
CARBON DIOXIDE: Addition to Greenhouse Atmosphere The natural slow growth of orchids equates with adequate consumption without the necessity of adding it to the atmosphere, but opinions differ. A65-388+; A65-899+ (in favor of adding it); A67-811; A79-798 (also in favor).Thin-leaved orchids and ferns supply additional C02 to thick-leaved orchids. OD71-21+ 0
CARBON DIOXIDE: Air Fertilization Data Experiments on non-orchid plants in Vermont; also on cattleyas in Tokyo; both with beneficial results; most effectively applied in the afternoon; use dry ice in coffee cans wrapped well in newspapers with cans punched with several holes in the lids; six cans to a small greenhouse. OD66-75 0
CARBON DIOXIDE: Enriched Atmosphere for Cymbidiums Braemar Nursery, Santa Barbara, Cal. use two Tectol gas-fired generators and report satisfactory growth improvements; plants flower in three instead of five years; 1,200 parts to one million of air; refer to OD67-4 0
CARBON DIOXIDE: Enrichment Effects On cymbidium and cattleya seedlings and mericlones it definitely stimulates growth; normal outside concentration is about 300 ppm.; 1,000 ppm. was found best experimentally; being heavier than air it lies in a blanket five feet from the ground; top ventilation is possible in warm weather. OD67-84+ 0
CARBON DIOXIDE: Ethanol and Methanol Alcohol Burning to Heighten Carbon Dioxide Content of Air Satisfactory if burned in greenhouse in small amounts; alcohol flame is invisible by day and dangerous. A69-242 0
CARBON DIOXIDE: Ethyl Alcohol Burning Side-effect of ethylene production seems small; such burning is harmless. A66-55 0
CARBON DIOXIDE: Fact or Fiction Answers to questions: what is it?; is it important?; why use it?; is it safe?; does it fertilize plants?; soil fertility levels?; greenhouse temperatures?; ventilation?; checking C02 levels; crop response?; sources; purity; summary of approval; refer to OD76-107+ 0
CARBON DIOXIDE: How to Create it in a Greenhouse Burn candles or an alcohol lamp. A70-725 0
CARBON DIOXIDE: Percentages of Composition In air it is about three hundredths of one percent; plants can use greater amounts to approximately 0.5 to 1%; data not related to orchids. OR72-34 0
CARBON DIOXIDE: To Accelerate Plant Growth Orchid tests carried out in Victoria, Australia with generator resulted in 25% additional growth, with spiking six weeks earlier. OD70-214 0
