Buying the right seeds is very important. For best results, purchase seeds from a reliable manufacturer and avoid purchasing seeds that are not suitable for hydroponic equipment. Make sure to use the correct ratio of nutrient solution and water. Use the lights properly and keep the light panels 1-2 inches from the top of the plants. Make sure to use the grow dome correctly as directed in the instructions. Keep them in an environment between 15 - 30° C (59° F - 86° F).
