Description

Potent, fast and fruity, indica-dominant auto strain.

Watermelon Auto is a cross of Tropicanna Cookies and Lemon OG with added ruderalis genetics providing the auto-flowering properties with selections taking place over several generations. Watermelon Auto is a fast-finishing strain, 75% indica, 20% sativa and 5% ruderalis, and has an intense terpene profile with the emphasis on limonene and myrcene. Good indoor production and high levels of THC await growers.

Grown indoors, Watermelon Auto plants grow to be 70 - 110 cm. tall producing as much as 500^gr/m2 just 8 - 9 weeks after germination. Left to their own devices plants grow with a strong central cola but low-stress training levels out the canopy resulting in the highest yields. Outdoors plants can be grown directly in the ground or in pots and raised beds. Plants will grow a bit taller at 90 - 120 cm. producing up to 100 gr/plant. Growers in regions with warmer climates will be able to produce more than one crop per year. Buds are dense and sticky with resin.

A rich terpene profile delivers watermelon and other tropical fruits scents and flavours with an earthy finish. THC levels reach 20% and the effect is that of a typical indica with medium levels of CBD to reduce any 'edginess'.

Very low germ rate plus small size. I ordered this strain a couple orders ago through a buy one get one offer and out of 10 seats I only had three germinate and all three plants ended up being less than a foot tall. I have ordered and successfully grown a wide variety of autoflowers and this particular strain from this particular Seed Company was literally the worst performing seed that I ever received from the multiple orders I have done at Seedsman. I should have contacted Seedsman about this strain and I should have written a review about this poor performer much sooner. I am surprised that seeds men is still charging $10 a seed almost for this product and even though I got to buy one get one.. three out of 10 seeds was not worth the BOGO offer. The potency was fair considering the plants were tiny.

After my last review I wanted to add this. Seedsman is a really good supplier (especially their own brand), it was just this strain that dudn't cut it
