WHEN IT COMES TO PLANT GROWING IN A GROW TENT THE SUPERIOR WHITE REFLECTIVE MATERIAL WILL OUTPERFORM THE SILVER MYLAR. 
Light measured in PAR (what plants need not humans) it is shown that the more even distribution of the PAR light will get better growing results than that of silver mylar of the highest standard.  White Wins in tests carried out using the best of the best silver mylar grow tent against white reflective material. 
White has always been considered too expensive. 
BUT NOW WE CAN BRING YOU WHITE GROW TENTS AT THE BEST PRICES. 
If you are a serious grower (especially if you use LED) White grow tents are the way to go. 
These grow tents also have strong material externally using the better 600d rather than 210d 
They also have 19mm poles as against the lighter weight 16mm poles. 
There are also numerous ports for ease of connection of your ducting. 
When you buy a silver mylar grow tent with 16mm poles the box weight is about 12KG for a 1.2 x 1.2 tent but for our white it is 18KG you should be asking yourselves what i am i not getting for the extra 6KG which is 50% more!!! 

If you are looking for a one season grow tent then this is perhaps not the grow tent for you but if you are looking for a quality product then consider this one carefully, i am sure you will agree the quality is very good value indeed.
