The buds will probably be potent, but the quantities will be even less than you imagine... keep one to the end for the learning experience but use the space better by starting again. Think of your electricity bill over the whole : will it be worth 6grams of weed or more? I'm the type of guy that rather pay more but get more, and if i was you i would start again using all you've learned - the sooner the start the sooner the harvest, that's why it's important to use your grow room space wisely. Hope this helps ! 🚀
