Kelp naturally contains lots of trace elements and minerals that have protective properties for plants. Studies have shown that supplementing with kelp can increase plant yields, growth rates, and heat/drought resistance for many species of plants.

Put your main pot inside a bigger container to protect roots from baking in direct sunlight.

Many outdoor growers are dealing with unusually high temperatures during their summer grows, and many of you have written in with pictures of outdoor cannabis plants that are wilting and drooping, with leaves that are twisting, curling, flipping up at the edges, or otherwise getting majorly stressed by the heat.

6.) Breezy Spot If Possible

A “Plant Humidity Tray” is basically a tray full of gravel and then filled with water. Place the plant on top of the tray, and as the water evaporates it cools the air directly around the plant by a few degrees.

Besides protecting against heat, kelp supplements may also enhance seed germination, increase uptake of plant nutrients, and give more overall resistance to frost and fungal diseases.

4.) Keep Roots Cool

Heat Stressed Leaves Look Unhappy Around the Edges

When the plant is under direct sunlight and the heat gets out of control, try to move the plant indoors or offer shade if possible. Some growers will erect a mesh shade net over the top of their plants during the hottest days of summer if a shadier spot is unavailable.

From seed/clone to harvest takes about 3-4 months, so you could have 3-4 big harvests a year with this method, in which you cut down all of your crop and then replant a whole new crop once done harvesting.

I met many others in the farming community of St. Thomas. People grew bright and amazing fruits and vegetables foreign to the Northwest’s soil: mangoes, papayas, avocadoes, coconuts, pineapples, bananas, sugar cane, and coffee. A lot of farmers also grew cannabis. (To be clear, cannabis is illegal in the Virgin Islands, although they recently voted in medical cannabis.)

Cannabis is a photoperiod plant, its flowering cycle triggered by a reduction in light—outdoors, this is when the sun starts to go down in the sky as fall approaches.

Whether growing indoors or outdoors, your veg structure needs to be light-tight. If growing outdoors, you’d need to add additional lighting inside your greenhouse so that plants can get the full 18 hours of light they need while in the vegetative stage.


You don’t need much supplemental light on a daily basis—only an additional four or five hours and the sun will provide the remaining 12 hours. You’ll need to spend some money on electricity for additional lights, but not as much as you would in a strictly indoor operation.

Tropical climates can teach a lot about growing cannabis, both indoors and outdoors. Whether or not you like the heat and humidity of the region, your burgeoning cannabis plants love it.

According to farmers in St. Thomas, there are two ways to go about cultivating cannabis in the tropics:

Why Grow Cannabis in the Tropics?

A lot of cannabis farmers in the tropics generally grow “seasonally,” meaning that the entire crop is grown and then harvested. It’s not exactly “seasonal” though because the consistent sunlight throughout the year means you can grow multiple harvests a year.

Local growers tend to prefer the latter setup.
