    Let's Settle This! 250w vs 400w: A common question with conflicting answers.

    Thats an interesting point. I didn't consider grow air being pulled into the light ventilation through leaks by sucking air through the system. Pushing the air through just doesn't seem like it would work though. This will require some research to see what others have done.:dunce:

It was always the plan to have the light air-cooled separately. (not through the filter) Does air-cooling a rectangle hood require...

    Let's Settle This! 250w vs 400w: A common question with conflicting answers.

    Thanks for the awesome reply. 2 things to point out that I didn't mention originally. This is a DIY bubbleponic (basically a DWC, with continuous pump feeding). Also, for my first indoor grow I didn't set this up to be a perpetual harvest. As this is only for personal use, and will only hold 2...

    Let's Settle This! 250w vs 400w: A common question with conflicting answers.

    Hey Everyone! First post on this forum and I'd like to thank everyone in advance for taking the time to help a grower new to indoor gardening. Hopefully this thread can also help many others with similar dilemmas. My growbox has been built with 2'D x 3'W x 4'H dimensions as this fit my space...
