i couldn't tell ya, its a first for me, never bothered to build a structure to house them before, just moved them around outside. i got that 3 way meter that will reach all the way to the pot of the pots to check for moisture levels. seeing as how it rained yesterday, there all about 9-10, and as far as answering ur question, im not to sure, i haven't thought about switching building materials. nor a difference in Naming the structure. thats the first time i've ever been informed of two different styles of Greenhouse so to speak. i just went and checked them a second ago. on the light meter, it goes from 0-2000.
0 being dark, 2000 being direct light, the greenhouse doesn't get direct sunlight till 12 exactly, but as of 11 there getting inbetween 800 - 1000 on the meter, so i wouldn't worry bout materials passing light. but i am a lil concerned about temp, its easily a good 10 degrees warmer/+ more humid.
the one thats been in there is bushing out great, a good color, the bottoms leaves from being burned are the only ugly thing about it. im bout to have to start tying the top down and topping it again, im not to sure how many there are now, over a dozen fer sure. there was a spider on it also, i sprayed them down really good yesterday with that insecticde too, and still found a spider. as far as strain, it came out a bag of good popcorn nugs awhile back.
comments, advice, and feed back always appreciated
