poz svima.
ode ja malo citat guide-eve na mandala stranicama i bome sam neugodno iznenaden sa nekim stvarima
.
npr.
"Is it necessary to add anything for drainage such as perlite, vermiculite, sand, expanded clay pebbles?
It is best not to add any additional materials to your potting soil. Horticultural grade potting soil is perfectly mixed for the best air-water ratio. Adding more non-nutritive substances depletes the water retention capacity of the soil, it unnecessarily "stretches" the soil and reduces the total amount of nutrients available to the plant, and it creates dry pockets in the container.
Adding a large amount of perlite/vermiculite (some growers add as much as 25%!) is a completely outdated practice from 30-40 years ago when there was only a very small selection of horticultural potting soil available for non-commercial gardeners. It is one of the unfortunate harmful practices in cannabis cultivation that many still cling to although they do not understand the reason or consequences.
Especially harmful is to fill the bottom of the container with coarse materials such as expanded clay pebbles. This is where most roots grow down looking for water and nutrients! If they reach a dry and sterile layer of substrate the delicate root hairs shrivel, valuable space is lost where the plant requires rich soil that stores moisture and minerals."
i ono sto me posebno pogodilo i sto mi je nevjerovatno jer koliko sam vidio do sad svi hvale biobizz:
"What about Dutch soil mixes sold in the grow shops?
Up till now we have not received any satisfying feedback on Dutch soil products except for CANNA Professional. We do not recommend soil products from Bio Bizz or Plagron
. Most of them are too strongly fertilized for indoor cultivation and others are too light and require a complicated supplementary feeding schedule with liquid fertilizers. For example, All Mix has an EC of 2,4! That will easily burn your plants and create many complications. Plagron Royalty Mix and Plagron Bat Mix are also "hot" and contain guano. Bio Bizz Light Mix requires a feeding program and is not sufficiently pre-fertilized for natural growth. The point of growing in soil is to have an easy and uncomplicated cultivation and that is not guaranteed with these products."
ja sam uzeo atami light mix (uvalili mi umjesto biobizz light mix) za germinaciju i ranu vege (10-16cm vaze) i allmix za kasniji grow (25l vaze)
moze malo komentara na ovo od iskusnijih ?
