GROWBOT LIGHT DEPRIVATION FULL
The GrowBot includes sensors for humidity, CO2, temperature, water level, RGB camera images, and actuators to control the grow conditions, including full spectrum lights, IR lights, and UV lights, nutrients pump, water pump, air pump, air change pump, and fan. The GrowBot is a tabletop-sized greenhouse automated with sensors and actuators to become a robotic system for the control of plant’s growth.
We present the GrowBot as an educational robotic system to facilitate hands-on experimentation with the control of environmental conditions for food plant growth. Based on these promising results, hydroponics, therefore, can be recommended as an alternative to soil based cultivation techniques and may be explored further for sustainable crop production and global food safety. Hydroponically grown plants showed a more luxuriant and faster growth rate, earlier initiation of flowering and fruiting and three to four times higher yield than the soil grown plants. The soil grown and hydroponically grown plants showed distinct differences in their germination rates, plant vigour, root morpho-anatomy, pigment contents etc. and Capsicum annuum L.The success of hydroponics in the present study was found to be greatly dependent on the nutrient uptake which was found to be largely controlled by the pH of the medium and best growth was observed with a half-strength Hoagland solution having a pH of 5.8-6.0. The present study was carried out with the objectives of analyzing different hydroponic cultivation techniques and testing their potentialities to be used as a supplement to conventional farming for the cultivation of some vegetable crops like Lycopersicon esculentum Mill., Solanum melongena L. The hydroponic gardening concepts have been used since ancient times but the concept is gaining popularity only in the recent past especially in the context of acute land crisis and global food security.
Hydroponics is a science of growing plants in nutrient solutions with or without the use of an artificial medium for providing mechanical support to the roots. Evaluation of hydroponic cultivation techniques as a supplement to conventional methods of farming. Citation: Gurung CT, Bhandari JB, Gurung A.
