Biotabs?

Don't use them. Bio Bizz light mix is crap too, not enough nutrients, that is why they have to push the tabs to make their soil adequate. The tabs require your soil to be constantly moist to work properly and as we all know, cannabis does not like soggy feet. Plus they are really random in what they release and when, so not ideal for peak performance and are probably best used by people who can't or won't lift a watering can. Buy some proper nutrients for grow and bloom cycles and then you can tailor your plants nutrition to what stage it is at, rather than feeding something that is adequate all the time, but not really correct at any time. Far better to use a three way blend of Sunshine all purpose planting mix, Scotts potting soil and Supersoil potting soil or a half and half blend of Fox Farm Ocean Forest and Happy Frog. You get either a Happy Ocean or Forest Frog this way! For super simple feeding with one bottle for grow and one for bloom, B.A.C. make Organic Grow and Organic Bloom and they are both Vegan! Otherwise my favourite super simple mix is Bio Vega and Bio Flores made by Bio Canna, but half strength is plenty powerful enough. Another great product is made by GHE and is their pair of Flora Nova Grow one part and Flora Nova Bloom one part, also a complete fertilizer system for each stage of growth or flower. Add some seaweed tonic, an organic P/K booster (B.A.C.) and something with fulvic/humic/amino acids (or all 3 for best results), and you can't go wrong. Another thing I recently trialled and was super impressed with was "Mykos" made by Xtreme Gardening and is available most anywhere and on eBay too, this product is awesome for soil cultivation! It is basically a probiotic beneficial bacteria that increases nutrient uptake and I was surprised at how much less feeding was required for plants that were given these mycorrhizae. They live a symbiotic relationship with the plants roots and certainly are effective. All 3 nutrient ranges I recommended are all very concentrated, meaning very little of each is needed, therefore one bottle of whichever will last many, many plants, making them quite economical in the long run. I have found half strength Bio Vega for growth and full strength Flora Nova Bloom one part to be a winning combination, but the B.A.C. stuff works just as well. I have a bottle of each of these nutrients and feed them in rotation throughout the cycle, that is , once with Bio Vega, once with Flora Nova and once with Organic Grow, but I am a bit OCD and using just one product is more the enough if you don't want to buy 6 products. I also at times, will blend my nutrients, giving half this and half that or a third of each at one feeding, due to FOMO, combined with my OCD. Remember, you only get out what you put in. Grow economically and you get economical buds. Use premium ingredients and you get premium plants! Hope this helps,........... Organoman.
