BioTabs Fertilizers: The Revolution in Organic Indoor Cultivation
BioTabs fertilizers represent a revolutionary approach to plant nutrition in indoor cultivation. This Dutch brand has developed a 100% organic fertilizer system in the form of tablets that slowly dissolve in the substrate, gradually releasing all the necessary nutrients. No more complicated mixtures and haphazard dosages: with BioTabs, you nourish your plants naturally throughout their life cycle.
Why choose BioTabs fertilizers for your cultivation
The main advantage of BioTabs is its ease of use. The tablets are placed directly into the substrate and dissolve over 8 to 10 weeks, covering the entire cultivation cycle. No need to calculate EC or constantly monitor pH – the buffered system naturally maintains balance. The StarterKit - BioTabs - Complete pack for organic cultivation contains everything you need to get started: tablets, Startrex, Mycotrex, and Bactrex for complete nutrition.
Another strong point is the exceptional taste quality of the harvests. BioTabs organic fertilizers naturally develop terpenes, resulting in more pronounced and authentic flavors. The system also encourages the development of a healthy microbiome in the substrate thanks to the beneficial bacteria and fungi included. To boost flowering, the OrgaTrex - 1L - BioTabs - Growth and flowering booster provides a liquid supplement rich in amino acids and algae extracts.
How to choose your BioTabs products
To get started with BioTabs, the StarterKit remains the most logical choice. It contains 10 tablets (enough for 5 x 20L pots), 250ml of Startrex to mix with the substrate, plus Mycotrex and Bactrex inoculants. If you are already cultivating organically and just want to try the tablets, you can get a pack of 100 tablets, which covers about twenty pots.
For substrates, BioTabs works perfectly in pre-fertilized potting soil, but also in coco with the addition of Startrex. Just avoid overly draining substrates like pure perlite. As for liquid boosters, OrgaTrex is used once a week during flowering at 5ml/L, while Boom Boom Spray is sprayed directly onto the leaves to stimulate resin production.
Frequently asked questions about BioTabs fertilizers
How many BioTabs tablets should I put per 20-liter pot?
For a 20-liter pot, you should use 2 BioTabs tablets placed halfway up the pot during repotting. The tablets should be pushed about 5-7cm deep so that the roots can easily find them. This dose covers the entire cultivation cycle, from growth to the end of flowering. If you are growing in smaller pots, adjust proportionally: 1 tablet for 10L, 3 tablets for 30L.
Do I need to measure pH or EC with BioTabs fertilizers?
No, that's precisely the advantage of the BioTabs system! Organic fertilizers create a natural buffering effect that automatically maintains the pH between 6.0 and 7.0. EC is also irrelevant since organic nutrients are not detected by conventional testers. You simply water with tap water (if it's not too hard) or with slightly acidic water at pH 6.5. This simplicity is what makes BioTabs so popular with beginners.
Does BioTabs work well in coco fiber or only in potting soil?
BioTabs works very well in coco, but you absolutely must add Startrex to the substrate. Pure coco has no microbial life, whereas BioTabs tablets need bacteria to decompose properly. Mix 50g of Startrex per 10L of coco, plus a pinch of Mycotrex and Bactrex. In pre-fertilized potting soil, 25g of Startrex is sufficient because microbial life is already present. Coco gives excellent results once properly prepared.
How to mix Startrex with the substrate for BioTabs?
Startrex is mixed dry with the substrate before watering. Use 25g for 10L of potting soil or 50g for 10L of coco. Mix thoroughly by hand or with a trowel to evenly distribute the granules. Then add Mycotrex (1g per 10L) and Bactrex (1g per 10L) by sprinkling them over the mixture. Lightly moisten and let it rest for 24 hours before repotting. This preparation activates the microbial life that will decompose the tablets.
Can the soil with BioTabs be reused for a new crop without changing everything?
Yes, it's even recommended! The substrate enriched with BioTabs develops a very rich microbiome that would be a shame to discard. After harvesting, remove large roots and add 20% new substrate plus 25g of Startrex per 10L of mixture. Let it rest for 2-3 weeks for the microbial life to regenerate. You can easily reuse the same substrate 3-4 times. Some growers keep their "super soil" for years by enriching it with each cycle.
