Check out my thread on growing grass Indoors and the mixes I used
I agree though. Way easier to grow it outside and seed with winter grass and summer grasses. I'm not growing grass Indoors this year since I planted a bunch of grass outside.
Mine is about the same size this is what I did check out the thread. Used leftover roof pannels since they were free. When i expand I'll might use wood boards.
I grew about 10 medium pumpkins this year so im feeding hugo one a week or so once the grass slows down. I chop It in quarters and he eats it all along with everything else in his pen. Winter grass in coming in nicely!
I've done it with a regular home one for Hugo's winter box. Usually keeps humidity around 60 instead of the teens. But I have to fill it every day with distilled water. Might invest in a bigger tank this year though
I concur with Tom on that seed mix I grew trays last winter with great success, also the seed in my large enclosure. I have a small thread on here just look through my profile for a setup idea for growing grass in trays.
You could always do leafy greens there are so many that are cold hardy. Migardner.com have some good seeds and are a great price for the quantity. Also baker creek farms at rareseeds.com great germination from these people! Also turnip greens, collards, chard, dino kale is good too. gotta get to...
I order seed from multiple sites.
groworganic.com for their horse pasture mix which has multiple grasses and clover, even some alfalfa has sprouted up.
Desertseedstore for other mixes.
Also just search for flowers n food that he can eat and order those seeds n plant them.
My mom still makes them around christmas!
She always uses lard. They don't bake, taste or melt in your mouth if ya dont! No orange either don't know what that is doing in there..
I spy your four legged best friend
I have spread a bunch of mulch in my sulcata outdoor enclosure for ramps, trees and to grow grass (keeps the birds from eating the seed) No problems yet. Not purchased from the big box store. (Those can have herbicides, dyes and other stuff)
