New offer will be open on my home page 22nd of December - just before Christmas, and it is my Christmas present to all bulb and especially Crocus lovers.But before New Year, most likely at Christmas, new Crocus species from me will be published in International Rock Gardener.
With this textile called Agryl P17 how many degrees ared gained(2-3??). I'm also thinking of buying a roll.
Janis,Is Agryl P17 different from horticultural fleece which we buy in the UK?
I don't know. I only just bought it for the first time and now I'm everyday checking temperatures in greenhouse and below cover. As I already wrote - it is used by very famous Estonian bulb grower and author of many books about gardening, paeonias and bulbs - Sulev Savisaar. He use it to protect crocuses grown in outside garden and making leaves already in autumn. With me those species always died in open garden, but next year I will try to plant some of them in open ground and to cover with this "textile". There are several types of it - in the first half of greenhouse where crocuses are placed I used type 50g/sq.m., in another half is two layers of 17 g/sq.m. In shop they recommended 50 g production as better to protect against frost, but they hadn't more of it, so I bought half of 50 g and for another half double amount of 17 g. Will see the difference. Price was the same for both halfs. All covering cost for me 69,- Euro (80 m of 50 g/sq.m and 160 m of 17g/sq.m) together. I think that up to minus 10 C it must work, but when temperature will drop below for longer time, I will return glass-wool sheets.Just returned from greenhouse. Outside temperature at this moment is minus 5 C (-4,8), inside greenhouse - minus 2 C, but below cover, between pots +2 C.
I suspect it is much the same - there are differing "weights" of fleece available here too- but nothing I've seen shows a direct comparison between the types we usually see here in the UK. Heavier weight fleece is more durable, of course and in the UK the types are usually seen as 17gm and 35 gsm types. It appears that the Agryl textile comes in 17, 19, 22, 30 and +50 gsm ( gms per square metre) weights
