For one, the genetics of a particular strain will have a huge effect on its color and whether or not you can get flower buds that look as purple as gummy candies.
I’ll never forget my first pathetic attempt at growing marijuana in my house years ago. I bought an AeroGarden which is a small hydroponic growing setup marketed for tomatoes, other vegetables, and herbs. It came with strong lights and a water tank in the bottom with an aeration pump like a fish tank. They were on sale at Target at the end of the summer, so I got mine for 50% off. I never had any intention to grow vegetables with the machine, but instead wanted to try growing cannabis. In theory this would have been a great idea, but the lights couldn’t be raised high enough. Cannabis plants can grow as high as eight feet if they aren’t trimmed to be stout and fat, but the AeroGarden could only raise the lighting attachment up to fifteen inches from the base. The second my plant started to grow to maturity, it was growing into the lights and out the side. Eventually I had to give up the process when the plants failed to flower. I had wanted to grow purple cannabis, but I later learned that those batches result from a combination of different factors. For one, the genetics of a particular strain will have a huge effect on its color and whether or not you can get flower buds that look as purple as gummy candies. The temperature around the plant during its flowering stage affects the end color, as well as the nutrients. This is why it’s hard for a novice grower to expect that their initial crops will have these beautiful colors in them. It’s gorgeous and some of the prettiest marijuana I have ever seen.
