Schedule I Weed Guide: The Strains With the Best Profit-Per-Day, Ranked

Most Schedule I weed guides rank strains by sell price and stop there. That misses the number that actually matters once you’re running more than one pot: profit per in-game day. Grow time is identical across all four strains, which means the strain with the highest batch profit also wins on a daily basis — but Speed Grow, PGR, and Fertilizer change that math the moment you start stacking them, and getting the stack wrong can lock you out of your best customers without you noticing. This guide ranks all four strains by profit-per-day, then breaks down exactly what each growing additive costs you in quality versus what it buys you in speed or yield.

Everything below covers raw, unmixed weed straight off the plant — the numbers you’re working with before you ever touch a Mixing Station. Once you start adding ingredients, sell prices climb well past these base figures, and which strain you started with stops mattering as much as which effects you stacked on top of it. That’s a separate optimisation problem covered in our ingredients guide, linked below. This guide answers the question that comes first: which strain and which grow setup should you be running before you ever reach the mixing table.

Quick Start: Get Your Weed Operation Profitable in 5 Steps

Skip the trial and error. This is the order that gets a new grow operation profitable fastest:

1. Buy OG Kush seeds from Albert Hoover. It’s the only strain available at Street Rat I and the cheapest seed in the game at $30 [1].
2. Start in a Grow Tent ($100, Dan’s Hardware) instead of buying a separate pot, rack, and light. It’s the cheapest way in and only around 5% slower than a basic pot setup [5].
3. Skip additives on your first few harvests. Default Standard quality already clears the bar for Northtown and Downtown buyers — you don’t need Speed Grow or PGR yet [1].
4. Sell at roughly 1.6× the suggested price in the Products app; that’s the community-tested ceiling before customers start declining [1].
5. Rank toward Hoodlum II, then Hoodlum IV. That unlocks Green Crack and Granddaddy Purple — the two highest profit-per-day strains in this guide.

The Four Weed Strains, Ranked by Profit-Per-Day

Granddaddy Purple wins on raw numbers, but it’s not the right call for every stage of the game. Here’s the full breakdown, using a 12-unit pot harvest at Standard quality with no additives, and the base grow time of 5–7.5 in-game hours (average 6h15m) that the wiki’s own profit testing uses [1]:

*Profit-per-day = batch profit ÷ grow time expressed as a fraction of a 24-hour in-game day (6h15m ≈ 0.26 days). Figures rounded to the nearest $10.

One honest caveat: the wiki doesn’t document any per-strain difference in grow speed [1], so converting to a daily rate doesn’t reorder the list — it just rescales it. What it does buy you is a number you can compare directly against meth and cocaine once you unlock them, since profit-per-day is the same unit regardless of product. That’s the actual point of thinking in daily terms instead of per-unit price: it’s the metric that survives the transition when you outgrow weed (see our Schedule I mixing recipes ranked by profit for what the same math looks like on meth and cocaine).

Two numbers are worth a second look before you default to Granddaddy Purple. First, return on seed cost: OG Kush turns its $30 seed into 13.9× profit, versus Granddaddy Purple’s 10.5× — if you’re cash-constrained early, OG Kush is still the better dollar-for-dollar bet, not just the beginner-only option most guides frame it as. Second, addictiveness: Green Crack’s 34% addiction rate is by far the highest of the four strains, and the wiki’s own price testing shows fully addicted customers pay roughly 15% more and accept slightly larger orders than non-addicted ones [1]. Green Crack sits second on raw profit-per-day, but the strain builds a base of high-value repeat customers faster than either of the two strains that beat it — a factor a one-time batch-profit number can’t capture.

Growing Time vs. Quality: What Speed Grow and PGR Actually Cost You

Speed Grow and PGR both promise a better harvest, and both quietly cost you a full quality tier if you use them alone. Neither the pop-up description nor most community guides spell out how badly that stacks — and it matters because quality doesn’t raise your sell price directly. What the wiki’s own testing shows is that quality mostly controls which neighborhoods will buy from you at all: Northtown accepts almost anything, Downtown wants Standard minimum, and Suburbia and Uptown — your highest-value customers — expect Premium or better [1]. Grow the wrong quality and you’re not losing a few dollars per unit, you’re losing entire customer segments.

Here’s exactly what each additive combination does to a base 12-unit pot harvest:

The trap is in that fifth row. Stacking Speed Grow and PGR together drops you two full tiers to Trash, and Fertilizer only recovers you back to Standard — not Premium, not Heavenly [2][3]. If you’re chasing Suburbia or Uptown buyers, the full speed-and-yield stack is actively working against you: you’ll harvest more, faster, of a product those customers won’t touch. Fertilizer used alone, with no speed or yield boost, is what gets you into Premium territory. As a general guideline, run the full additive stack for Northtown-and-Downtown-tier volume selling, and drop to Fertilizer-only the moment you want access to the top two neighborhoods.

Grow Tent vs. Pot vs. Air Pot: Which Setup Actually Pays Off

Your grow setup matters almost as much as your additive choices, and the decision changes depending on how far into the game you are:

• If you’re at Street Rat I with under $500 saved: use a Grow Tent. At $100 it bundles the pot, light, and rack into one purchase, grows weed in about 6h50m, and only needs watering once per cycle [5].
• If you’ve got Hoodlum-rank cash and want higher yield per cycle: switch to a basic pot setup (suspension rack + plastic pot + halogen light). It yields 12 buds against the tent’s 8, and despite the higher output it’s only around 5% slower than the tent — a smaller penalty than most players assume [5].
• If you’re running multiple pots and optimising for cycle time: upgrade to an air pot with a full-spectrum growing light. It grows roughly 33% faster than a basic pot setup, which compounds fast once you’re not limited to one grow at a time [5].

The Drying Rack Math: When Heavenly Is Worth the Wait

A Drying Rack ($250, unlocked at Hustler III from Oscar’s Store) is the only way to reach Heavenly quality [4]. It’s also slow: each drying cycle raises quality by exactly one tier and takes 12 in-game hours at base temperature, dropping to a minimum of 8 hours per cycle if you keep it near an AC Unit running at 40°C/104°F [4]. Taking a Trash harvest all the way to Heavenly costs three full cycles — 36 in-game hours base, or 24 hours fully AC-optimised. That’s roughly six times longer than growing the plant that produced it in the first place. Worked example: a Poor-quality OG Kush harvest reaches Standard after one 12-hour cycle, Premium after a second (24 hours total), and Heavenly after a third (36 hours total) — or 24 hours total if the rack sits at a constant 40°C/104°F the whole time [4].

One detail that catches players off guard: using PGR for the yield bonus means you’re starting every harvest one quality tier lower, which increases both the number of racks you need and the number of drying cycles required to hit your target tier [4]. If you’re running a high-PGR, high-volume operation, budget more drying capacity than the raw unit count suggests. Verdict: skip the rack entirely while you’re still selling into Northtown and Downtown — Standard quality already clears their bar. Once you want Suburbia or Uptown routes, or you’re running Granddaddy Purple at scale, the rack earns back its $250 in a day or two of Premium-tier sales.

Which Setup Fits Your Playstyle

The “best” strain and setup depends on where you are in the game and how much you’re optimising:

FAQ

Is Granddaddy Purple really the best weed strain?

By raw profit-per-day, yes — but it’s gated behind Hoodlum IV, which takes real playtime to reach. Green Crack unlocks two tiers earlier at Hoodlum II and its 34% addictiveness builds a repeat-customer base faster, which matters more than the roughly $30/day profit gap if you’re still expanding your customer list rather than maximising an established one.

Should I use Speed Grow or PGR first?

PGR, generally. Its yield bonus (+33% in a pot) compounds every time you replant, while Speed Grow’s time savings only matter once you’re bottlenecked on grow slots rather than on cash or ingredients. A new player with one pot gets more value from a bigger single harvest than from finishing that harvest sooner and then standing around waiting to replant.

Is the Drying Rack worth it just for weed?

Not until you’re trying to sell to Suburbia or Uptown. Quality gates which customers will buy from you rather than how much they pay per unit [1], so if you’re still working Northtown and Downtown, Standard-quality weed already clears their bar and the rack’s 12-hour-per-tier cost isn’t buying you anything yet.

Does strain choice affect anything besides sell price?

Yes — addictiveness. OG Kush and Granddaddy Purple carry 0% addictiveness, Sour Diesel 10%, and Green Crack 34% [1]. Higher addictiveness means customers pay a premium (roughly 15% per the wiki’s price testing) and buy in slightly larger quantities once hooked, so two strains with a near-identical base price can produce noticeably different income once your customer base matures.

Should I bother growing all four strains, or just specialise?

Specialise unless you’re a completionist. Running one strain at a time means every rank-up, every Fertilizer purchase, and every Drying Rack cycle you learn applies immediately to your main income line. Splitting output across four strains spreads your ingredient and drying-rack capacity thin for the sake of variety you mostly need for mixing experiments, not raw profit — and mixing is a downstream problem the mixing recipes guide handles separately.

Key Takeaway

Start with OG Kush in a Grow Tent because it’s the cheapest way into the economy, not because it’s the best long-term strain. The moment you can afford Fertilizer, use it alone rather than stacking Speed Grow and PGR on top — that single change is what keeps your Premium-tier customers in reach while you grind toward Hoodlum IV and Granddaddy Purple’s ~$1,820/day ceiling. And once meth and cocaine come online, the same profit-per-day math applies at a much higher multiplier — see our Schedule I production guide for the full quality-and-mixing system across every product, or our ingredients guide for which mixing additives return the most per dollar spent.
