Hey Guys, ive been using the PK 13/14 for a couple of grows now with combinations of the Terra and Bio ranges and both boosts (not together obviously) i started out using as canna suggested which i understood to be 2.5ml per litre for one week during week 6/7..the label isnt the most coherent set of instructions when stoned.. the guy at the store said the idea was to basically cram as much as you can into the 6th or 7th week,
anyway i saw good results using it as Canna recomend, the potency + overall yeild especially increased. This last grow though i decided to use it earlier on, @ 0.5ml per litre twice a week from 4.5 weeks and built up the dosage gradually until about week 6-7 when i was at full 2.5ml every other day. During the first two weeks i had to be careful not to overdo it but overall i think my results were better over using it the way the bottle tells me to.. i use soil btw.
just to add an fyi, from using the bio boost and boost accelerator which i thought were both great products i didnt really notice any difference between them and the non bio Boost (Boost Accelerator) is £5 more than the Bio verion..
and...sorry but some folk may find it useful... Terra Vega is £10something and you apply at 5ml per litre, whereas the Bio Vega is £12something and you apply at 2ml per litre. You dont have to be a day trader to see that the Bio is considerably cheaper.
