Finally got them set up and compared to the "shoebox" method, I'd go with the Mark 1 all day errday. So much so I ordered to more. Get the humidity meters also......A1 product.
Love these tubs! I was doing DIY tubs and after experiencing both…these pre made tubs are well worth their price and actually a cheaper option in the long game. They look great and I can grow up to 15 on most shelving units. 2 thumbs up
I ordered several small monotub packages. When they arrived a few of the lids were damaged from shipping. I sent an email and was immediately told they would send replacement lids. They sent them in a timely manner, excellent customer service!. I highly recommend doing business with MICROPPOSE, they deliver and stand behind their products. I must add, the package was packed properly with plenty of cushion. The box was clearly damaged in shipping. Great products, great customer service.
These tubs are very high quality. I have tubs from 3 different vendors and these are by far the best. So much that after getting my first two, I order three more. These are very sturdy and it’s nice that you can buy them with the liner and filters.
Great for beginners or experienced. Makes it easy. If you measure correctly, two can fit on an inexpensive plastic shelving. Has everything you need for every stage of growing except maybe something to keep it dark in the beginning. I used a garbage bag and worked great.
Little disappointed when the clips are applied to the side of the mono tube they don’t securely stay clipped on and easily fall off, maybe a manufacturing's error with the ub mold or clips cause my first tube was not like this, little bummed but will make it work
Great design. Great quality. Great functionality. Could not have wanted anything more.
Glad I didn’t waste time and end up with questionable results by building my own.
Can’t wait till my mycelium matures and I can start using it.
