Collection 1

Medical Seeds Collection 1 Feminised Cannabis Seeds

Medical Seeds Collection 1 is a feminised mix pack containing six cannabis seeds — two each of Prozack, Channel+, and Sour Diesel — from one of Spain's most respected medical seed banks. Instead of committing to a full pack of one strain, you get a sampler that lets you grow three genetically distinct plants side by side and figure out which one suits your garden (and your preferences) best. We've carried Medical Seeds for years, and this collection is one of the smartest ways to test their lineup without buying three separate packs.

What's Inside This Cannabis Seed Collection

You get six feminised seeds total, split evenly across three Medical Seeds strains. Each strain brings something different to the table, so your garden won't be a monoculture — it'll be a proper test run.

The standout here for a lot of growers is Channel+. Finding a strain that produces meaningful levels of both THC and CBD in the same plant isn't as common as seed bank marketing would have you believe. Channel+ genuinely delivers on that front. Prozack, meanwhile, is the one you want if you're into making hash — the genetic diversity in that line produces resinous flowers that process well. And Sour Diesel is Sour Diesel: that unmistakable fuel-and-citrus nose that fills a room the moment you crack a jar open.

Why a Cannabis Seed Mix Pack Makes Sense

Buying individual packs of three strains means committing to 9–15 seeds and spending significantly more. This collection gives you 2 seeds per strain — enough to grow one of each with a backup in case of a dud germination. We see a lot of growers come back after running a mix pack and order a full pack of whichever strain they liked best. It's a try-before-you-commit approach, and it works.

The honest limitation: two seeds per strain doesn't give you much room for pheno-hunting. If you're after the absolute best expression of Sour Diesel, you'd want a full pack to select from. But if you're growing for personal use and just want variety in your tent, two seeds is plenty. One plant of each strain in an 80x80 tent fills the space nicely.

All six seeds are feminised, so you won't be pulling males. That matters when you've only got two seeds of each — losing one to a male plant would cut your sample in half. Medical Seeds' feminisation process is reliable; in the years we've stocked their gear, complaints about hermaphrodites have been rare.

How to Grow These Feminised Cannabis Seeds

These are photoperiod feminised seeds, not autoflowers, so you control the vegetative and flowering phases with your light schedule. Here's the straightforward approach:

1. Germinate seeds using the paper towel method: place seeds between two damp (not soaking) paper towels on a plate, cover with a second plate, and keep at 22–26°C. Taproots typically appear within 24–72 hours.
2. Transfer sprouted seeds taproot-down into small pots (0.5L) filled with light, airy seedling soil. Plant about 1cm deep. Keep the soil moist but not waterlogged.
3. Provide 18 hours of light and 6 hours of darkness during the vegetative stage. These three strains respond well to 3–5 weeks of veg in an indoor setup.
4. Switch to a 12/12 light cycle to trigger flowering. Expect 8–10 weeks of flowering depending on the strain — Sour Diesel tends to run a bit longer than Prozack or Channel+.
5. Monitor trichome development with a jeweller's loupe. Harvest when trichomes shift from clear to milky-white with roughly 10–20% amber, depending on your preference.
6. Dry in a dark, ventilated space at 18–22°C and 55–65% humidity for 7–14 days, then cure in glass jars for at least 2 weeks. Patience here makes a real difference in the final flavour.

One thing to watch: because you're growing three different strains, they'll stretch and flower at different rates. Sour Diesel, with its Sativa influence, will likely grow taller than Channel+ or Prozack. Train or top the Sour Diesel early if you need to keep an even canopy under your light. Low-stress training works well here — just bend and tie the main stem during veg.

Cannabis Seeds and Terpene Profiles Worth Knowing

The three strains in this collection cover a decent spread of terpene profiles, which is part of what makes it interesting to grow them side by side. Sour Diesel is famous for its pungent fuel-forward aroma cut with sharp citrus — you'll smell it before you see it. According to research published in PMC, among the terpenes found in cannabis seed oil, beta-myrcene stands out for its significant anti-inflammatory and anticatabolic effects observed in human chondrocytes (PMC, 2024). That same terpene is present in many Diesel-family strains.

Channel+ brings a more balanced cannabinoid profile to the table. Having both THC and CBD in meaningful quantities is what originally put Medical Seeds on the map in Spain's medical growing community. According to a complete review on cannabis seed phenolic compounds, several studies have tested cannabis seeds for their anticancer potential, revealing effects that are often cell-type dependent and extract-specific (PMC, 2025). Research in this area is still developing, but it shows why growers interested in the full cannabinoid spectrum keep coming back to strains like Channel+.

Prozack rounds things out as the hash-maker's choice. The genetic diversity in this strain means resin production is generous, and the flowers process well whether you're doing dry sift or bubble hash. If you've never made hash from your own plants, Prozack is a solid strain to start with — the trichome heads separate cleanly.
