30c and 44%? It'll dry fast. 4-5 days? When it first feels dry/cripsy on outside, it probably has 1/2 day longer to dry. If you seal it up and the outside gets soft/moist again, remove from sealed container and let it dry longer. Get some boveda 2-way humidity packs . They give room for error. they can absorb a few grams of moisture or provide some, if needed.
so many variables impact drying time so it's hard to give a good estimate. bud size, bud density, temp, rh, circulation (hopefully not direct wind) etc...
you are doing what you can. You hung an entire plant which slows down drying. If it's 30c / 44% in future, i'd also wait to trim it... pruning off leaves speeds up drying process. Dry trim might help, but it wouldn't have made a huge difference here. handful of hours longer?
A better environment willbe mid 60F and 60% rh. Light is your worst enemy, followed closely by heat.
A small closed area during initial drying is not ideal. People use tents, but i don't know why. in a tent a ciculration fan or dehumidifier to cntrol the intial moisture gassed off would likely blast buds with lots of wind (increased evaporation rate) and heat. It can be done, but no reason to make it more difficult to do.
A small room with a circulation fan (not directly pointed at drying buds) is all you need. Keep it dark and as close to the temp/rh stated above and you'll have 9-14 day drying times... depending on wet/dry trim or hanging plants vs buds on a mesh rack etc etc...
i'd say as long as it takes ~5 days, it'll turn out 'okay but not great'. If it dries within 2-3 days it gets a noticeably worse smoking pleasure. Has that weird "green" taste. Sttrive to get it stretched out to 9-10 days as best you can. Too long and you risk microbial growth.
