When should I start adding nutrients when I’m growing with Batmix?

Batmix is ​​fertilized for about six weeks. When you need to start giving nutrients depends on conditions such as amount of light per m2, type of plant and other factors. You can start giving more nutrients once the leaves are more yello, thats after about six weeks.
Plagron has three organic soils which are pre-fertilized for 6 weeks.

How can I choose one of these three?

Due to its fertilization by Bat Guano, Bat Guano gives your plants a strong taste and smell. You should choose Batmix when quality is most important to you. Royalmix contains a selection of solid natural fertilizers that release nutrients when the plant needs them. Due to this you can expect a higher development and therefore a higher yield. Choose for Royalmix when you want to grow organically and when you want to go for the highest yield with a natural fruity taste. Plagron Allmix has a finer texture than Batmix and Royalmix. Due to this, it can hold more water better.This makes Plagron Allmix the right choice if you want organic growth, at high temperatures, in small pots or with high light intensity. Additionally Plagron Allmix is ​​ideal if you plan to reuse your soil and want to update it with Supermix.

Do I have to adjust the pH value, if I grow with Batmix?

No, combined with our 100% NATURAL Growing Style you do not have to adjust the pH value.
I read on the site that I have to rinse Batmix before using it. Why do I do this and how can I do this?
Our Batmix is ​​maximally fertilized. For young plants that are not yet accustomed to high EC-values, it can be difficult when they are suddenly planted in maximum fertilized soil. Therefore, we recommend rinsing the Batmix before putting the plant in the Batmix. This is done by filling the pot (eg 10 liters) with Batmix and rinsing with 5 to 10 liters of water. After that, the plant can be planted directly.Fertilizers that are directly absorbed will be flushed out with the water. In the following days, the EC Batmix value will rise again and gradually non-absorbable fertilizers will be released.

Can I mix Batmix with full soil when I’m growing ourdoors?

Yes, we advise you to mix Batmix in the ground when your soil is very clayey outside. If your soil is very aerated we recommend using Bat Guano.

I will be on Batmix. Can I start with plant nutrition like Alga Bloom after 4 weeks?

Batmix is ​​fertilized for 6 weeks. During a normal development of your installation, it is sufficient to start with the addition of plant nutrition such as Alga Bloom after 6 weeks. See appendix Grow 100% natural. If you choose to give extra nutrition (earlier than 6 weeks) we advise you to take a good look at the leaves of your plant. If the lower leaves (old leaves) of your plant change its color from light green to yellow, you can start with adding Alga Bloom.
