Indica And Sativa.
Before you can begin to grow, you’ll need marijuana seeds or clones. There are 2 species of cannabis that are grown to supply marijuana, they’re Cannabis indica and Cannabis sativa. Although there are dozens, if not masses of marijuana strains, most strains used to grow marijuana are generally indica, principally sativa, or an indica / sativa mix. Everything considered, generally indica plants are easily the best plant for hydroponic noobs growing inside. They’re simpler to grow, do not get as tall, and produce a bigger crop than sativa plants. The sole disadvantage is indica plants have lower THC levels than sativa plants, this makes them less powerful.
As a grower gains experience they may try growing an indica / sativa mix. When extremely experienced, an indoor hydroponic grower may try a principally sativa strain. But for the first few crops, stick with indica or indica / sativa plants.
