1) Light feeding:
When it comes to overall grow times, sativas take longer than indicas and need less food per watering. Err on the side of caution and use less than the recommended amounts of nutrients unless you see a deficiency arising.
2) Selective pruning early:
Whether you prune, pinch or incorporate LST (low-stress training), it’s important to keep sativas short and stocky. Employ these techniques during the vegetative stage.
3) Lower your lights:
In terms of growth, sativas stretch long and lanky, and one way to reduce this is by keeping your lights (preferably metal halides) closer to the canopy. Raise them as your plants reach upward.
4) Training tops:
Use a ScrOG (Screen of Green) system to guide growing branches through a horizontal chicken-wire screen at canopy level. This spreads future colas around and maximizes space.
5) Give roots room:
Larger containers for your medium will result in bigger plants with higher yields. Plan on needing at least 1 gallon of container space per week of vegetating time and you’ll harvest more abundantly.
6) Longer flowering times:
Some Hazes can flower for up to 20 weeks! This means elongating your budding schedule to accommodate many more days of watering and flowering.
7) Flower early:
Because Haze plants will stretch for weeks after the flowering cycle is induced, start the budding period earlier to wind up with a manageably sized plant. Between 1 and 2 feet is an ideal time to begin flowering.
8) Support growing branches:
Even well-grown sativa tops will sometimes overwhelm the plant’s own ability to hold them up. Use a trellising system or attach branches to plant stakes.
9) Flush well:
During a lengthy period of growth, many salts and minerals will build up in the medium as well as in plant cells. Leach out excess nutrients with plain water for at least two weeks before harvesting.
10) Harvest when ready:
Even though they take more time, Hazes are definitely worth the wait. Allow the trichomes to mature and start to go cloudy (with some amber) before cutting the buds down for drying.
