The presence of white buds is a relatively new issue in cannabis cultivation, however there are various publications on the subject, such as that of Royal Queen.
First of all, you should not confuse white buds with albino flowers, which are of exclusively genetic origin, nor should you confuse them with flower discoloration problems caused by thermal stress which normally also causes the leaves to turn yellow.
The white buds we are talking about only affect the apex of the flower and are caused by a high quantity of trichomes, present throughout the plant, but, above all, in the flower and in particular on the top of this.
It has long been known that the amount of trichomes determines the quality and also the quantity of the harvest and it has now been proven that to achieve maximum quality and quantity 20-30% of the flowers must have white buds at the 7th-8th week.
In these conditions, it is not difficult, indoors, to achieve productions of 800 gr/m2 and yields of 3 gr/W, however, to achieve these values you need to have a very high knowledge of cultivation and obviously of lamps.
So these 8 particular elements are needed:
2) Particular spectrums
3) Special optics
4) Particular positions of the lamps
5) Variable power cycle of lamps
6) Suitable fertilizers
7) Tables of suitable shape and size
8) Density, pruning and shape of plants
