BAC Biotablets are your secret weapon for achieving lush, vibrant growth without the daily hassle of mixing nutrients. These 100% organic tablets are a complete, slow-release fertilizer system designed to nourish your plants and supercharge your soil's microbial ecosystem from the very first day. Just set them and forget them—your plants will do the rest.

Ever feel overwhelmed by the sheer number of bottles, schedules, and measurements involved in feeding your plants? You're not alone. That constant juggling act leads to mistakes, wasted money on unused products, and the nagging worry that you're either underfeeding or, worse, burning your precious greens. It turns the joy of growing into a chore filled with anxiety. But what if you could eliminate that complexity entirely? What if you could provide everything your plants need with a single, simple step at the beginning of their life cycle?

Phase 1: Preparing Your Substrate

Before you even think about seeds or clones, get your foundation right. Whether you're using a high-quality soil mix or a coco coir substrate, ensure it's fresh and well-aerated. This initial preparation is crucial for the Biotablets to work their magic effectively.

  • Check Your Pot Size: Know your container volume. The golden rule is one BAC Biotablet per 5 liters of substrate.
  • Moisten the Medium: Lightly water your soil or coco before planting. It should be damp, not soggy.
  • Plan Your Placement: Have a small tool ready to make a hole about 5cm deep near the edge of the pot, not directly in the center where the main stem will go.

Phase 2: Setting Up the Biotablets

This is the only "feeding" step you'll need for the entire growth cycle. It's straightforward but important to get right.

  1. Calculate: For a standard 11L planter, you'll need 2 tablets. For a 20L pot, use 4 tablets.
  2. Place: Using your finger or a dibber, create holes 5cm deep around the perimeter of the pot, about halfway between the center and the edge.
  3. Insert: Drop one BAC Biotablet into each hole.
  4. Cover: Gently cover the tablets with substrate and pat down lightly.
  5. Plant: Now you can plant your seed or cutting in the center of the pot.
  6. Water In: Give the pot a thorough watering to activate the tablets and settle everything in.

Phase 3: The Grow Cycle – Just Add Water

This is where the simplicity shines. From this point forward, your only job is to water.

  1. Germination/Seedling Stage: Water lightly as needed. The tablets are already working below, stimulating microbial life.
  2. Vegetative Growth: As roots expand, they'll reach the nutrient-rich zone around the tablets. You'll see vigorous, healthy green growth. Simply maintain your regular watering schedule.
  3. Flowering Phase: The slow-release formula continues to provide balanced nutrition. Your plants will focus energy on developing dense, resinous flowers. No need to switch to a "bloom" formula.
  4. Signs It's Working: Consistent, deep green foliage, strong stem development, and robust root growth are your indicators.
  5. What to Avoid: Do not add additional base nutrients. You can safely use complementary products like organic bloom stimulators if desired, but the core nutrition is handled.

Phase 4: Post-Harvest and Learnings

After harvest, you'll appreciate the clean simplicity. There's no salt buildup to flush aggressively. The used substrate, now enriched with beneficial bacteria and humic acids, can even be recycled for another run or added to your compost. Note how many weeks your plants thrived on just the tablets and water—this knowledge helps you plan future cycles with even more confidence.

Advantages of Using BAC Biotablets Over Liquid Feeding

  • Set-and-Forget Simplicity: One application feeds for months. No daily mixing, no pH juggling after the initial setup.
  • Zero Root Burn Risk: The slow, organic release is gentle. You'll never shock your plants with a hot mix.
  • Supercharged Soil Life: The tablets don't just feed the plant; they feed the soil. Beneficial bacteria and fungi flourish, creating a living, breathing ecosystem.
  • No Waste: Use every gram you buy. No half-used bottles gathering dust.
  • Perfect for Beginners: Removes the biggest point of failure for new growers: over/under-feeding.
  • Ideal for Busy Schedules: If you travel or simply have a busy life, your plants won't miss a beat.
  • Clean and Odor-Free: No messy liquids, no strong smells from bottles, just tidy tablets.

Frequently Asked Questions

Can I use BAC Biotablets in coco coir?

Absolutely. They are perfectly suited for both soil and coco substrates. Just remember the 1 tablet per 5L rule.

How long do the tablets last?

One application typically provides complete nutrition for an entire autoflowering cycle or a standard photoperiod vegetative phase. For very long flowering strains, a second application mid-cycle might be beneficial.

Do I need to adjust my pH when watering?

Since you're only using water, you should still pH it to the optimal range for your medium (6.0-6.5 for soil, 5.5-6.0 for coco). The tablets themselves help buffer the substrate.

Can I use them with other BAC products?

Yes, they are designed to work seamlessly with the rest of the BAC organic line, like their PK booster or bloom stimulator, for an extra kick during flowering.

Are they safe for all plants?

Yes. While we focus on cannabis, these tablets are excellent for houseplants, vegetable gardens, and ornamental plants.

Personal Experience of Pevgrow’s CEO (Alan)

Let's be real, I love tinkering with advanced nutrient schedules, but sometimes you just want things to work. That's why I always keep a pack of BAC Biotablets in my stash. I use them primarily for my "low-maintenance" runs—autoflowers in the summer or when I know I'll be traveling. The results are consistently impressive. The plants never show deficiencies, and the growth is steady and strong. My pro-tip? Even if you're a control freak like me, try them in one pot as a side-by-side experiment. You'll be shocked at how well they perform with zero effort. The biggest lesson I learned was to trust the process and resist the urge to add more. They really do contain everything needed. For beginners asking me where to start, Biotablets are now my first recommendation—it removes the fear and lets them focus on light, climate, and just enjoying the grow.
