Treatment of drainage solution from hydroponic greenhouse production with microalgae. Hultberg M., Carlsson A.S., Gustafsson S. Microalgae for biodiesel production and other applications: A review. ANSWER: Lettuce should be watered not daily but instead about twice a week, or once every four or five days, for most of its growing period. Check back daily for moisture needs and to watch for germination. Scratch them in gently or sprinkle a light dusting of soil or vermiculite on top. Sprinkle seeds on the soil surface where you wish to grow them. GOGAT PAL chlorophylls citrate sintase glutamine synthetase malate dehydrogenase. Lettuce seeds are generally happiest when direct-sown. quadricauda extract positively affected the growth of lettuce seedlings, mainly acting at the shoot level, determining an increase in dry matter, chlorophylls, carotenoids, proteins, and influencing the activities of several enzymes involved in the primary metabolism.

Planting in full sun will generate faster leaf production, but can encourage bolting during hot weather. Give lettuce plenty of room to mature by spacing plants 8 to 12 inches (20 to 30 cm.) apart. Lettuce plants were sampled at 1, 4, and 7 days from the first treatment and 7 days from the second treatment. For optimal growth, lettuce requires 1 to 2 inches (2.5 to 5 cm.) of rain or supplemental water per week. The experiment was performed by growing plants on inert substrate (pumice) with a 16-h photoperiod, by carrying out two consecutive radical treatments, one week apart, using a concentration of the extract corresponding to 1 mg Corg L -1. This is especially helpful when growing vertically, because starter plants add up fast and theres a lot of pockets to plant.
quadricauda extract on lettuce seedlings was explored by evaluating the physiological parameters, chlorophyll, carotenoid, and total protein contents as well as several plant enzymatic activities involved in primary and secondary metabolisms. The aim of this work is to investigate the potential use of a Scenedesmus quadricauda extract as a biostimulant in order to obtain sustainable cultivation and a reduction in the cost of chemical fertilizers in lettuce cultivation. Among crops, lettuce often requires the use of biostimulants to improve both the quality and quantity of production.
In particular, algal extracts are suitable candidates as they positively affect plant physiology. The use of natural biostimulants is becoming an attractive option in order to reduce the use of fertilizer and increase the yield of crops. In a few words, we start sowing indoors and transplant in the field or greenhouse, in most regions after the first frost.
