Tuna Kush is a tough strain to grow. On top of that, even if grown correctly, it will produce an extremely small yield of only about one ounce per meter square. This is an appalling rate of return on your time, space and money investment, so it’s not usually advised to grow it yourself unless you’re very keen to try this mysterious weed and can’t find a source for already-grown Tuna Kush.
Furthermore, you will need a carbon filter, which is not something every grower has. The “tuna” part of this weed’s name is included for good reason, and that is because it stinks like rotten fish at its worst. Even at its best, the strain has a powerful fishy scent that you’ll not be able to disguise effectively unless you have a system in place for tackling it. On top of these obstacles, you’ll need to chop the top of the plant down periodically as the leaves will shade the rest of it and cause it not to grow effectively, resulting in an even smaller yield than you would already get. Finally, it needs to be kept in a dry environment. Like its supposed parent, Tuna Kush doesn’t like humid atmospheres.
Apart from that, the usual standards apply when growing this cannabis plant that apply to most effective growing. Make sure the soil is healthy and that the plant gets plenty of light. For feeding, we recommend during the 4-week grow cycle to keep it in 18 hours of light followed by 6 hours of dark. Use 4ml of pH perfect Sensi Grow A & B (or something equivalent) for the first week, 8ml for the second week and 16ml for weeks 3 and 4. For supplements, use 8ml of B-52 and Voodoo Juice for the first two weeks, and 8ml of B-52 only for weeks 3 and 4.
Once bloomed, 16ml of pH Perfect Sensi Bloom A & B should be added in each of the first 8 weeks. To get the most out of your seeds, add 8ml of Voodoo Juice in weeks 1 and 2. In weeks 2 through 5, add 8mls of Big Bud a week. Use 8mlsB-52 in weeks 3 through 7, and top it off with 8ml of Overdrive in weeks 6 and 7. Remember in week 8 to use no nutrients so that the plant has a chance to flush them all out.
Even if you use this complicated nutrient cycle (which isn’t a necessity to grow the weed), you still won’t push the yield up beyond 1 ounce per square meter. Nevertheless, if you’re someone who thrives on adversity and likes their victories only when they’re hard-won, this bud is the challenge you’ve been looking for.
